E-flite takes electric ducted fan performance and engineering to new heights with the Plati-num Series Habu 32 DF. Designed around the E-flite Delta-V 32 80mm fan unit and 2150Kv DF32 brushless motor, it uses hyper-efficient ducting that allows this power system to pro-duce large amounts of thrust without resorting to drag-inducing cheater holes. Match this power system with an E-flite 6S 5000mAh 30C Li-Po pack and an 80A Pro brushless ESC and youve got a sport EDF with exhilarating speed that will give even experienced jet jockeys goose bumps.

As the first Platinum Series E-flite ducted fan, the Habu 32 DF also boasts a level of fit and finish that is every bit as impressive as its performance. Its sleek fiberglass fuselage comes pre-painted and integrates the vertical stabilizer. The fully-sheeted wings and horizontal sta-bilizers are mounted with carbon blade spars and covered with genuine UltraCote covering. Add the optional E-flite 15-25 Size Electric Retracts, and the Habu 32 DF really stands out from the crowd.

Carbon-Z is a revolutionary composite construction technique developed by world aerobatic champion Quique Somenzini. It uses a patent-pending technique to fuse the lightweight durability of Z-Foam with the strength and rigidity of carbon fiber.

The result? Airframe structures that are unbelievably strong Light weight for low wing loading and better thrust-to-weight ratios Excellent rigidity for more precise response Can be repaired at the field so you can keep flying Durable exterior that looks good in all temperatures and weather

The Workshop SeasonFor those of us in the northern hemisphere, its the time of year to hibernate, or at least to hunker down indoors and stay warm. For modelers, that means having time to clear off the workbench so theres room to build (and repair!) aircraft so theyre ready for the upcoming fl ying season. Although I doubt many folks would say winter is their favorite time of year, I think of what a reader in sunny, temperate California once told me: I sure do love fl ying every day, but I never have any time to build airplanes, and thats a problem! His comment is a reminder that there is something to appreciate about the cold, snowy weather outside. And when you need a building break and are itching for some stick time, todays fl ight simulators are truly the next best thing to really fl ying. Ikaruss latest, Aerofl y 5, is a super-realistic program we review this month. In addition to the usual sport, scale and aerobatic planes and helicopters, Aerofl y 5 has great glider fl ying in different environments and even offers dynamic soaring with real speed recordings! Who knew winter could be so much fun?


Get in the Zone!With such a multitude of beginner-friendly planes, helicopters and trucks available, it has never been easier to get your kids or grandkids into RC. If youve been looking for a way to get the younger generation involved in a hands-on, active hobby, our latest special issue is just what you need. RC Zone is jam-packed with games, articles, tips and gear that will inspire and excite young readers, from indoor combat helicopters to electric jets to boats and even monster trucks. Pick up a copy today and get someone started in the hobby of a lifetime. This special issue is on sale now at newsstands, hobby shops, and AirAgeStore.com

Warriors of the LuftwaffeFlight Journals latest special issue, German Fighters, will satisfy the voracious appetite of aviation enthusiasts worldwide. If you are driven to learn all you can about Luftwaffe aircraft, then you dont want to miss out on this truly exceptional special issue. Not only do in-cockpit evaluations tell how the legendary Fw 190 and Bf 109 actually fl ew, but German Fighters also showcases the words of pilots who fl ew those aircraft into combat against Allied forces. Youll ride along as German pilots dive into battle in Stukas and skate around treetops to avoid marauding Allied fi ghters while fl ying the Storch. All of this

is supported by some of the best vintage German color photos ever presented, as well as the spectacular modern color photography for which Flight Journal has become renowned.This special issue is on sale now at newsstands, hobby shops, and the AirAgeStore.com

and Delta-wing designs. If you know the Diamond Dust, then you know I like to fl y then fast! At a recent club meeting (in my basement) the local experts told me that in fact there were no true full-size, man-carrying delta-wing designs out there. I disagreed, and so went the evening! After searching my collection of aircraft maga-zines, I came up empty. Please do you know of any real Deltas?

Max Watkins, email

Hey, Max, thanks for sticking up for Delta wings! Tell your buddies there are several Delta-wing aircraft, but most are experi-mental aircraft built by homebuilders in the Experimental Aircraft Association. A trip to Oshkosh during the annual Air Ventures fl y-in will usually fi nd one or two on the fl ightline or tooling around the pattern. Surely the highlight of any full-size fl y-in would have to be the amazing

TROJAN PROJECTU I just had to laugh when I received my January issue of Model Airplane News. Ive been looking at my almost fi nished T-28 project for at least three years now and just bit the bullet to purchase the power system. I built mine with no landing gear, I bungee-launch everything, and it came out very light indeed. The canopy/cock-pit fl oor is still an issue I need to solve, but overall it was a very good build. I bet it will fl y like a dream. Thanks for the prod in the butt to get this bird done.

Jay Beery, email

Jay, glad to oblige. We know there are many stalled projects in the RC workshops across the country. In this case, holding off a little benefi tted from advances in LiPo battery technology and less expensive brushless motor systems! Rich Uravitchs airplane designs are timeless and always a good place to start if you want to scratch-build from plans. You are all but guaran-teed success with any of Richs plans Good luck, and please send us some photos of your fi nished Trojan!

Beaver (plan no. 10891,) and I cannot find the CG location on the plans. I know with a constant chord wing usually 13 back from leading edge will be OK, but I dont want to risk it, as the model has taken a while to build. Thanks for your time and assistance.

Peter Hepworth, Liverpool, UK

Hello, Peter! The Beaver is a great-flying plane! We actually have a few here in Con-necticut, as we have plenty of lakes in the local area. It is a really tall machine sitting on the shore atop of some EDO floats!

We no longer have contact information

for the author/designer Ed Westwood, so for a first-time test flight, I would mark off the 25% and the 30% MAC positions of your constant chord wing, and balance within this range. Then, if you feel it nec-essary, move the balance back until you get the response and performance you are comfortable with. One third or 33% back is a bit aft for the scale non-aerobatic design, so start around 28% and test-fly it.

Good luck, and send us a photo of your DHC-2 Beaver! Wed be happy to feature it in our Pilot Projects section!

all-sheet-metal homebuilt called the Ver-hees Delta designed and flown by Bart Verhees. It has a wingspan of 14.76 feet, length is 10.82 feet (including prop/spin-ner), wing area is 107.63 square feet, empty weight is 463 pounds and maximum take-off weight is 750 pounds. Its cruise speed is 136.7mph with a Vne (never exceed speed) of 168mph. Its stall speed is about 53mph. The engine on prototype was a 50hp, 1600cc liquid-cooled Subaru EA 71. So what are you waiting for? Get to that work-bench and start building a scale model of it, and show those experts that they do exist!

Better late than neverU Just to let you know that I bought my first RC plane on October 28, 2010, from Extreme RC Hobbies in Quarryville, PA. I thought Id learn with a slow glider such as the Radian RTF. Just to make sure every-thing goes right the first time I fly, I pur-chased the Phoenix RC Simulator from HobbyTown USA. This was an excellent choice since it has the Radian as a model to fly. Being 67 years old and retired, I am getting a late start. I got the bug to do this from attending many RC shows at the Far View Fliers airfield near Hamburg, PA. Another item of importance I purchased was your Electric Flight magazine; it has made me more eager than ever to get out and fly as soon as we have some nice calm weather here.

Tom Falk, Reading, PA Tom, it sounds like youre off to a great start. Our sister publication Electric Flight (previously Backyard Flyer) is another great source of information especially for the electric fans out there. The Radian and the Phoenix RC Sim also are both great products, and you should progress quickly with these choices. A word of advice while flying: try to remember that when the plane is flying back toward you, that its left and right turns will feel backwards. When you move the stick left, the plane will turn to your right. A simple way to keep the wings level with the planes nose facing you is to move the stick to the lower wing-tip. Think of it as propping up the lower wing with your control stick! Works every time. Good luck, and have fun!

Useful hints from modelers

GO WITH THE FLOWAre you tired of getting that drop of CA that leaks out of the hinge line because the glue does not soak in all the way? This is a method I use to avoid this. Drill a 18-inch hole down in the center of the hinge slot. This is larger than most people do (116 inch) but it will allow the CA to fl ow all the way down into the hinge. You can even add the CA to the hinge in one of the surfaces fi rst, then join the surfaces so that the dry hinge half can point down in the slot and let gravity help with the fl ow. Arthur Deane, Northville, MI

USE YOUR BRAKESHeres a simple way to use an old clothespin to keep that park fl yer on the bench during a slightly windy day. Just use the clothespin as a chock block to keep the wheel steady and the plane from rolling away. Its very easy to carve away what you need to make for a custom fi t using a Dremel Moto-Tool. Robby Yearwood, Dallas, GA

GET A GRIPHere is an old trick that we use with screwdrivers, but it also applies to the world of the hex bolts. Take a little fuel line to retain the bolt onto the Allen wrench. This works great when trying to get that bolt in awkward or hard-to-reach locations. If the fuel tubing wants to stay on the bolt, just use a cable tie to anchor it to the Allen wrench.Mark Phillips, Apple Valley, CA

GIVE IT A RESTI fi nd that I am always using my soldering iron and have to leave it on for long periods of time. The tiny soldering iron rest that came with the iron is always falling over and then I have a hot iron rolling around on my bench. I discovered that by bending a coat hanger as shown in the image, I can keep my hot iron in one place, all day long. Michael York, Big Bear City, CA

The Hangar 9 product line distributed by Horizon Hobby should be dubbed the Fantasy Island of flying. These talented folks always seem to come up with some way to fill every possible RC flying interest or niche. Want to fly a jet, but cant afford a true ducted fan or turbine jet? Try the Jackal 50. If youre in the same boat as me, there are two issues with flying jets: find-ing a flying site that allows turbines, and the cost to play. The new Jackal 50 ARF has the performance to satisfy this particular fantasy!

Its a jet in every sense of the word, except there is a propeller on its nose. If it wasnt for the sound of the 2-stroke engine, with the Jackal 50 in the air, youd

be hard-pressed to tell whether it was a true jet model or not. Although a begin-ner would have no problem at all assem-bling this plane, it is definitely intended for at least an intermediate pilot with high- performance airplane experience. As with all Hangar 9 ARFs, as soon as you open the box you know its a top-shelf product. My first thought was, If Hangar 9 took as much care in building the airframe as they did in packing it, this is going to be an Alex Rodriguez grand slam! I was not disappointed.

UniqUe FeatUresThe Jackal 50 has a balsa/ply built-up air-frame sporting a three-color scheme cov-ered with UltraCote. The ailerons and flaps are factory installed, including the control horns. You have a choice of operational or

FLIGHTTEST HANGAR 9 JACKAL 50 ARF

At the fl ying fi eld, the Jackal 50 is very easy to set up for fl ight. As I mentioned earlier, I hard wired the retractable landing gear air plumbing as I transported the model in one piece with the wing attached to the fuselage. The main fuselage hatch provides plenty of access to service the radio and fuel system. I ran several tanks through the Evolution .60NX and adjusted the needle valve for max rpm then backed it off about 200 revs before the initial fl ight. The engine purrs like a kitten at idle and has a smooth transition to takeoff speed. With an 11x6 prop and the smallish tires necessary to fi t within the wheel wells, I found my runway a bit too rough for a smooth takeoff. The prop would snub the grass after going over a bump. I changed to a 10x7 prop, which also added to the top-end rpm, and I was able to take off nicely into the wind. This would not be a problem with a paved runway of a very short groomed turf strip.

GENERAL FLIGHT PERFORMANCEStability: Though the Jackal looks like a red-hot skyrocket on the ground, in the air, it is extremely stable. Much like a pattern ship, the model is not at all twitchy with the recommended control throw settings.

Tracking: Rock solid is all I can say. The Jackal feels very groovy in that in the turns, it locks in and comes around without any issues at all. On the ground, the nosewheel steering is responsive, which makes it easy to

keep the takeoff roll or landing rollout arrow straight.

Aerobatics: Again, the Jackal feels like a pattern ship on the wing, and it does all maneuvers very precisely. Loops are big and graceful, rolls are crisp, and 4-point rolls are easy with almost no pitch or yaw coupling. Inverted fl ight is also a piece of cake. But really, this beast is smooth and made for speed! Open up the throttle and blast it into the stratosphere! It has a climb rate you wont believe!

Glide and stall performance: Being very slippery and smooth aerodynamically, the Jackal has a very good glide performance. Should you have a fl ameout, just keep the nose down and you should be able to glide it in without much effort. Stalls are mild and well mannered.

PILOT DEBRIEFING The best bit of advice is you should always fl y the Jackal as it is intended, and by that I mean, keep an eye on your airspeed. The only place I got a little worried was in a slow, low fl yby for the camera. If you let the airspeed drop too much and then crank in a lot of aileron, you can cause a wingtip to stall. Always keep your low-speed passes one and a half mistakes high. Flown within its speed envelope, the Jackal is a solid, smooth and predictable airplane that can really move out! Open the throttle, and youll see that the Jackal doesnt just look like a jet, it fl ies like one too!

fi xed fl aps; I chose operational, of course. As for the landing gear, fi xed gear are supplied while mechanical or pneumatic retracts are options. I went the pneumatic route to tuck up the gear for even less drag and more airspeed. As a side note, install-ing the Robart retract system in this aircraft was the fastest, easiest I have ever done. I found that I can transport this aircraft fully assembled (wings on), so I did a more direct hard install with all air lines, eliminating the quick disconnects between the fuse-lage and wing. The real work is installing the fl ap and aileron servos. I followed the instructions and everything went together without a hitch.

When assembling the empennage, I made the ultimate mistake: I looked at the pictures and jumped into the build before reading. I found out the hard way that you have to attach the elevator to only one of the horizontal stabilizer before sliding it into place! The other elevator half goes on after the stabilizer has been glued in place. It pays to read the instructions! The only tight spot in the entire construction pro-cess is screwing the torque rod horn into


Robart Retractable Landing Gear InstallationWith a plane like the Jackal 50, retracts are absolutely required. You wont get top speed with the fi xed gear layout. The Jackal 50s instructions make dropping the gear in place a piece of cake. As mentioned earlier, I did not use the quick disconnects between the fuselage and wing to eliminate possible air leaks. Another area that needs special attention is installing the steering cables properly to the nose gear. Heres how I did it.

1Since the nose gear take a lot of abuse, place a few drops of thin CA in each screw hole to harden the surrounding wood. This helps prevent the screws from stripping out on a hard landings.

2 Pass the pull-pull steering cable through a copper crimp. Slip the wire through the hole in the steering arm then back through the crimp. For best results, use a crimping tool from the hardware store to secure the crimp in place. Secure each end of the cable to both sides of the steering arm at this time. Hint: If it is diffi cult to fi t the wire through the crimp, slightly fl atten the crimp to make it an oval shape so theres room for both lengths of cable.

3Use side cutters and cut the cable into two equal lengths.

4 Now install the nose gear assembly in the fuselage. Tighten the screws, but dont overtighten them or you may strip out the holes. Now insert the steering cables into their respective tubes in the fuselage.

5Make sure the nose gear is in the down and locked position before you attach the steering cables to the rudder servo.

6Prepare the cables by sliding a copper crimp on the wire, then a pull-pull fi tting. The cable then goes back through the copper crimp. Do not crimp the cable, as it must be adjusted before securing the crimps.

7 Install the brass pushrod connectors in the rudder servo output arms, then insert the wire pull-pull fi ttings. With the end of the pull-pull fi tting extending inch through the connector, lightly tighten the connectors lock screw to hold the fi tting in place. Do this on both sides.

8 Adjust the cables so there is light and equal tension on both cables. Turn on your radio, and check to make sure that the rudder servo is centered. The nosewheel should also be parallel to the fuselage centerline. If you need to adjust the cables, use needle-nose pliers or hemostats to apply tension to the cables, and then tighten the connector setscrews.

Plenty of room for radio and air system for the retracts; the Robart air valve is shown here.

the rudder torque rod (thin fi ngers come in handy). As for installing the radio and retractable landing gear, half of the upper fuselage is removed with the fl ip of a latch, so work room is a nonissue. The fuel tank comes factory assembled; just slide it in place and secure. With an open engine

compartment, installing the powerplant is a piece of cake. Something Hangar 9 did that I wish everyone would do is ship the fi berglass cowl in a thick, clear plastic cover. The clear cover is used as a template. You make all your marks and cuts on it to get a good fi t, then slip it over your cowl

to transfer the cowls cut lines. You end up with a nice, clean, professional-looking fi t the fi rst time. The fi nishing touch is a beautiful, white powder-coated aluminum spinner supplied in the kit.

BOTTOM LINEThis was one of the easiest ARFs Ive ever built. It assembled in almost no time, and the parts count is very low. Everything fi t as it was supposed to, and the large fuse-lage hatch opens up the top making for very easy access. Right down to the pneu-matic retracts, installation and assembly was trouble free. If I had to guess, Id say you can get this jet-like fl yer from the box into the air in about seven hours. When you feel the need for speed, the Jackal will answer the call. The Evolution .60NX with a high-performance muffl er and a 10x7 prop give the Jackal plenty of get-up-and-go!

A neat feature is that both the fl ap and aileron servos are under one wing hatch.

Fuel Systems Made EasyThe first step in keeping your engine running

MARCH 2011 45

Radio control model airplanes rely on two basic systems to fly, the radio system and the power system (excluding gliders). Whether you have a nitro-burning glow engine or a high-octane, gasoline-sipping powerplant, if your engine loses its fuel supply, youll find yourself in a dead-stick situation with a plane that wasnt designed to be a glider. To prevent dead-stick landings, the first steps are taken at the workbench while you install the fuel tank and other necessary fuel-system com-ponents. Though this is an easy task for experienced builders, newcom-ers may find it a bit of a challenge. This article will highlight some of the basics of the fuel components that feed your models engine and will make all that plumbing more understandable.

THE BASICS Just like the family car, the fuel tank con-tains the engines fuel supply. The tank is connected to the engines carburetor with flexible fuel line (plastic tubing), and a rubber stopper seals it. For a tank to oper-ate properly, it must have a vent line that allows air to enter the tank as fuel is drawn out. It relieves the vacuum left in the tank. Model airplanes dont always fly straight and level. To allow the fuel to flow at differ-ent attitudes, the tank has a flexible inter-nal pick-up tube. A heavy clunk fitting is attached to the end of the pick-up tube to always keep the end of the tube at the lowest part of the tank. If the pick-up tube wasnt flexible, once the fuel level dropped below the pick-up tube, the supply of fuel would stop and the engine would die.

Lengths of brass tube pass through the tanks rubber stopper, and the fuel lines that carry the fuel to the engine slip over the ends brass tubes. The rest of the fittings and acces-sories help the fuel system work properly and make it easier to maintain and operate.

BAd VIBESOne common problem that can lead to your engine running lean is fuel foaming in the tank. Vibration causes this and it forms tiny bubbles in the fuel. The bubbles cause erratic fuel flow and the air in the bubbles causes the fuel mixture to lean out. The simple solution to this is to make sure to properly pad your fuel tank with

Fuel filters are worth their weight in gold! Clean fuel means no trash in the tanks.

Whenever possible, pad your fuel tank with foam rubber

Fuel Systems Made Easy

soft foam rubber. Also, make sure that after time, you check the padding to see if any part of the unprotected tank is coming in contact with the models inner structure like a former or engine mount bolt or nut. I prefer to use rubber bands to hold the foam padding in place but you can also use tape. Make sure you dont compress the foam too much as this will lessen its ability to isolate the tank from the vibration.

Regular maintenance is key to keep-ing your entire model in top condition. One way to keep a better eye on your fuel system is to make the tank removable. When there is no fuel tank compartment hatch, I make a slide-in tank tray from lite-ply and a matching set of rails inside the fuselage. This way, I can slide the tank into place and secure it with a couple of small screws. You can save more space by attach-ing your battery pack to the tray as well.

two-LINE SEtUP A two-line fuel system is the simplest and almost foolproof way to go. The setup requires only two pieces of brass tube, a clunk, a rubber stopper and a short length of silicone tubing. Bend one tube 90 degrees to form the vent and insert it through the stopper. The vent lets outside air in as the

Making your fuel tank easy to get to makes maintenance of your fuel system easier to do.

The removable fuel tank tray can also secure your battery packs.

This system works extremely well, espe-cially with larger, gasoline-powered planes.

To choose the correct size fuel tank for your airplane, check your kits directions or check the engine manufacturers recom-mendations. Youll want a tank that can hold enough fuel for a 15 to 20 minute flight.

Adding a fuel filter to your fuel supply line gives you double protection.

The simplest and most trouble-free setup is a two-line tank.

Three-line tank setups allow convenient tank filling without removing the fuel line from the engine.

2-line setup

3-line setup

fuel is drained out, and it acts as an overflow indicator when you fill the tank. The second tube is the fuel-supply for the engine and the interior pick-up tube and clunk are attached to it. To fill the tank, the fuel supply tubing is removed from the carburetor and attached to your filler pump line. When the tank is full, you simply reattach the line to your car-buretor. The vent line is often attached to a pressure fitting on the engines muffler. This arrangement helps pressurize the tank to enhance fuel flow to the engine.

three-line setup In a three-line tank, the setup is just like for a two-line arrangement, but a third

line is added and used to fill the tank. The third line doesnt need an interior pick-up line and clunk, but many do add them to allow the removal of fuel at the end of the day. Before running your engine, you must seal off or cap the third line to prevent fuel from leaking out. Fuel line plugs called Fuel Dots are available commercially to do this, but you can also use a tight-fitting machine screw or a short piece of 18-inch-diameter brass rod material as well. In a pinch, you can use a one-inch length of 18-inch dowel.

This is a typical trouble spot. Vibration can cause the fuel line to fray and cause a leak.

gasoline-powered engines. Unlike glow engines, which use a venturi vacuum to draw the fuel into the carburetor, most gas engines use pumper carburetor to draw fuel from the tank. The placement of the tank is not nearly as critical as for glow engines. Also, the gasoline carburetor has a dia-phragm pump, which prevents fuel flow-ing into the engine unless it is running.

To fill a gasoline tank, you can add a T-fitting to the engines fuel supply line with an added length of tubing. When you pump fuel into this line, it only flows into the tank and wont flood the engine. When the tank is full, plug the fill line and the engine draws fuel from the tank. By adding a long fill line and using a Fuel Dot, you can place your filler cap anywhere you like, this is great for scale models with large fiberglass cowls that hinder easy access to the fuel lines.

46140.indd 1 12/6/10 11:05 AM

TroubleShooTingProperly installed, your fuel system will last a very long time and may never need to be changed. In a hard landing, however, some of its parts may be dislodged or a line can become kinked or pinched. Here are some common fuel-flow problems and fixes.

After a hard landing, the flexible pick-up tube and clunk inside the fuel tank can be forced all the way forward. This can go unnoticed until the next flight when the tank stops delivering fuel to the engine in a nose-high attitude. To prevent this, solder a short piece of brass tube to your clunk. This decreases the pick-up tubes flexibil-ity a bit but still allows it to draw fuel in normal flying attitudes.

If your engine starts to run lean for no apparent reason, check for small pinholes in the fuel-supply lines. Check closely where ever there is a tight bend or where the fuel or line comes into contact with the firewall. To help prevent chafing at the fire-wall pass-through, drill a small hole in the firewall and use a length of brass tube in the holes. Slip the fuel lines over the brass tubes to complete the system.

If your engine begins to run erratically, debris may have gotten into your fuel system. It usually finds its way into the models fuel tank from your fuel storage jug, and if it blocks fuel flow, your engine will die. To prevent this, use an in-line fuel filter in the fuel supply line just before the carburetor. Install another filter in your fuel-pump line so you fill your tank with filtered fuel. Add a combination fuel clunk/filter, and you have a triple defense against dead-sticks.

All sorts of fuel filler fittings are available. T-fittings and fuel dots can be used for gas engine setups.

The T-30 Katana is one sharp airplane. Purposely designed and built for aero-batic competition by Pietro Terzi, it exudes incredible performance. Able to withstand +10/-10G loads, it will roll at a rate of 400 degrees per second, and I read that the large wing fairings provide an aerodynamic continuum and are why the plane excels at flying at high angles of attack. Having flown plenty of Katanas from stick-built to ARF, 40-inch to 40%, I can say this is a true statement, as they harrier extremely well. Phoenix Models offers a pair of Katanas, and I reviewed the EP (electric-powered) model. At about 50 inches, it is a good size and should fly great. Its built out of ply and balsa with plenty of structural integ-rity. Covered in Oracover, the scheme is bright and very easy to distinguish. Along with the built-up and covered fuselage and empennage parts, the model includes plug-in wings that are easily removed if you have limited space or a smaller vehicle. Aluminum landing gear, tailwheel, alu-minum wing-joiner tube, foam wheels,

fiberglass cowl and wheel pants, a plastic spinner, canopy and all necessary hard-ware needed to build the plane are in the box. The instructions are in the form of a nine-page booklet and fall a little short; I recommend you get help from an experi-enced builder/pilot if you havent built a few ARFs before.

UniqUe featUresCA-type hinges connect all control surfaces to their counterparts. It is recommended that you first drill a small hole in the center of each hinge slot; this allows the glue to better find its way into the wood for a stronger bond. I used BSI InstaFlex (bsi-inc.com), which is specifically made for hinging in this manner. Good-quality linkages are used in the form of adjust-able metal rods and clevises. The instruc-tions show the use of two elevator servos, which is fine, but I decided to eliminate the extra weight in the tail and use only one. I did this by adding an elevator joiner, and there are two easy ways to do this (see side-bar). The fiberglass cowl is one of the more heavy-duty ones Ive come across, and its paint colors match the covering well.

As the fl ight battery is located under the motor box, you will have to cut an open-ing large enough for your battery pack in the cowls bottom; I did this quickly with my Dremel Moto-Tool and cutoff wheel. Once complete, you will be able to access the preinstalled hook-and-loop straps and battery tray.

Small plastic thumbscrews hold the large canopy and both wings onto the fuselage, while metric socket-head fasten-ers and washers anchor the landing gear.

I have taxied the plane around in my local park (it has medium grass) without issue. Just watch those elevator counterbalances, and dont dig in too deep. The 12-inch prop cleared easily, and it seemed like the wheel pants acted like skis, keeping the wheels light. Using a 3-cell LiPo, I estimated my power system input at 130 watts per pound, which gets the plane in the air quickly and allows it to climb up to your desired aerobatic altitude with ease. Im sure you could go up a size with the power system or any part of it for more ballistic performance. Set up as tested, the plane is perfectly capable of delivering a wide speed envelope and delivers plenty of mild 3D maneuvers. The wing is thick, the fairings add to the wing area, reduce drag and produce lift on the full-scale aircraft, and it doesnt seem to hurt this one! Harrier landings are possible and are easiest when you practice a bit and consistently dial in the correct elevator and throttle inputs; the slight wing rock is easily manageable. When approaching the runway from normal fl ight, it felt best to let the plane fi nd its own sink rate and be ready on the sticks with slight inputs to keep the Katana level and straight until touchdown.

GENERAL FLIGHT PERFORMANCEStability: High-alpha fl ight is quite stable for this class of airplane. Designers/engineers are constantly tweaking airfoils, add-on gadgetry, chord, thickness, and plenty of parameters to make these planes fl y well. At speed, the plane is stable in all axes and exhibits no bad characteristics.

Tracking: My CG was a little aft of the recommended specifi cation, so I did need a few clicks of trim to have the plane fl ying how I wanted. Even in the slight breeze, it stayed on course just fi ne.

Aerobatics: Upright or inverted high-alpha fl ight is easy to manage, rolls are fast on high rates, loops can be done in all sizes, and snaps and fl at spins are very dramatic. Knife-edge fl ight is doable, and I was able to hang it on the prop at the upper end of the throttle.

Glide & stall performance: I was quite surprised by how well the Katana glides and fl oats at lower power settings. Stalls are what youd expect from a 4-pound built-up model; the nose will drop followed by a wingtip.

PILOT DEBRIEFINGThe Phoenix Katana is a great plane for the intermediate pilot looking to practice sport aerobatics and get the feel for some 3D maneuvers.

I added some BSI thread-lock to the main gear screws and to all metal-to-metal con-nections. The tailwheel is small and light and fully capable of steering the Katana with ease. A couple of screws into the fuse-lage keep it in place, and the connection to the rudder uses two more screws that pass through two plastic brackets. When I added those unmistakable wing fairings, I removed the covering from the fairings and peeled back the covering on the wing. After I had used thick CA to join them, I was able to iron down the wing covering on top of the fairings to eliminate air gaps and create a cleaner look. I used Blenderm tape on the fairing bottoms and on all hinge lines to conceal their seams. Your motor of choice is secured with blind nuts, and once installed, I marked the cowl loca-tion using some blue painters tape and a

pencil. When I drilled into the wood for the cowl screws, I added a drop or two of thin CA to the holes to harden the areas and allow for better screw-holding ability.

CONCLUSIONThe level of completion is not as high as on some models, and after some slight modi-fi cations, I logged in about 12 hours con-structing the Katana. The build is not diffi -cult, and you could always contact the air support online should you come across any issues. Be sure you check the models center of gravity, and use your lighter-weight electrical components to help keep your fl ying weight to a minimum.

FLIGHTTEST PHOENIX MODELS KATANA

Can one be better than two?One thing I noticed about the Katana is that it called for two elevator servos, which can easily be confi gured through your transmitter or with wires and reversing devices, etc. I also considered the weight of the servo and the fact that it was to be installed into the aft end of the aircraft. By joining the elevator halves before installing them, you can save a servo, linkage and servo extension. Heres what I did:

It is imperative that you work on a fl at surface. Ive been known to work on the granite kitchen counters when no one is looking. Making sure the elevator halves are joined level to each other is as important as the units structural integrity.

With a sharp razor blade, remove the covering where you will add either a metal or a hardwood joiner, and relieve the wood where the chosen joiner will be attached. I used the razor and my Dremel Moto-Tool to cut away the wood areas.

Once cleaned up, I drilled some holes into the mating parts to spike the adhesive and add a little more surface area. I used 15-minute epoxy, and once cured, beveled the hinge-line surface
