    INTRODUCTION.

    Thank you for choosing the SEAGULL FUNFLY 3D ARTF by SEAGULL MODELS COMPANY LTD.The SEAGULL FUNFLY 3D was designed with the intermediate/advanced sport flyer in mind. Itis a semi scale airplane which is easy to fly and quick to assemble. The airframe is conventionallybuilt using balsa, plywood to make it stronger than the average ARTF, yet the design allows theaeroplane to be kept light. You will find that most of the work has been done for you already. The motormount has been fitted and the hinges are pre-installed. Flying the SEAGULL FUNFLY 3D is simplya joy.

    This instruction manual is designed to help you build a great flying aeroplane. Please read thismanual thoroughly before starting assembly of your SEAGULL FUNFLY 3D . Use the parts listingbelow to identify all parts.

    WARNING.

    Please be aware that this aeroplane is not a toy and if it is assembled or used incorrectly itwill cause injury to people or property. WHEN YOU FLY THIS AEROPLANE YOU ASSUMEALL RISK & RESPONSIBILITY.If you are inexperienced with basic R/C flight we strongly recommend you contact your R/C supplierand join your local R/C Model Flying Club. R/C Model Flying Clubs offer a variety of trainingprocedures designed to help the new pilot on his way to successful R/C flight. They will also be ableto advise on any insurance and safety regulations that may apply.

    INSTALL THE AILERONS CONTROLHORN.

    1) Locate the hardware necessary to installthe control horns for the ailerons.

    8) After both ailerons are securely hinged,firmly grasp the wing panel and aileron tomake sure the hinges are securely glued andcannot be pulled out. Do this by carefullyapplying medium pressure, trying to separatethe aileron from the wing panel. Use cautionnot to crush the wing structure.

    7) Repeat this process with the other wingpanel, securely hinging the aileron in place.

    6) Using C/A remover/debonder and apaper towel, remove any excess C/A glue thatmay have accumulated on the wing or in theaileron hinge area.

    5) Turn the wing panel over and deflect theaileron in the opposite direction from theopposite side. Apply thin C/A glue to eachhinge, making sure that the C/A penetrates intoboth the aileron and wing panel.

    Work the aileron up and down severaltimes to “work in” the hinges and

    Note:

    4) Deflect the aileron and completelysaturate each hinge with thin C/A glue. Theailerons front surface should lightly contact thewing during this procedure. Ideally, when thehinges are glued in place, a 1/64” gap or lesswill be maintained throughout the lengh of theaileron to the wing panel hinge line.

    The hinge is constructed of a specialmaterial that allows the C/A to wickor penetrate and distributethroughout the hinge, securelybonding it to the wood structure ofthe wing panel and aileron.

    6) With the stabilizer held firmly in place,use a pen and draw lines onto the stabilizerwhere it and the fuselage sides meet. Do thison both the right and left sides and top andbottom of the stabilizer.

    5) When you are satisfied with the align-ment, hold the stabilizer in place with T- pinsor masking tape, but do not glue at this time.

    Pen.

    7) Remove the stabilizer. Using the linesyou just drew as a guide, carefully remove thecovering from between them using a model-ing knife.

    Remove the covering.

    8) Using a modeling knife, carefully re-move the covering that overlaps the stabilizermounting platform sides in the fuselage. Re-move the covering from both the top and thebottom of the platform sides.

    When cutting through the covering toremove it, cut with only enough pressureto only cut through the covering itself. Cut-ting into the balsa structure may weakenit.

    4) Install the stabilizer onto the fuselage.Align the centerline drawn on the top and therear of the stabilizer with the centre of the fu-selage. When that is aligned, hold the stabi-lizer in that position using T-pins or maskingtape. Align the horizontal stabilizer with thewing. When viewed from the rear, the hori-zontal stabilizer should be level with the wing.If it is not level, use sandpaper and sand downthe high side of the stabilizer mounting plat-form until the proper alignment is achieved.The tips of the stabilizer should also be equaldistance from the tips of the wing.

    10) After the epoxy has fully cured, re-move the masking tape or T-pins used to holdthe stabilizer in place. Carefully inspect theglue joints. Use more epoxy to fill in any gapsthat may exist that were not filled previouslyand clean up the excess using a paper toweland rubbing alcohol.

    HINGING THE ELEVATOR.

    Epoxy.

    1) Carefully remove the elevator from oneof the fuselage panel. Note the position of thehinges.

    2) Remove each hinge from the fuselagepanel and elevator and place a T-pin in thecenter of each hinge. Slide each hinge into theelevator until the T-pin is snug against theelevator. This will help ensure an equal amountof hinge is on either side of the hinge line whenthe elevator is mounted to the fuselage .

    3) Slide the elevator on the fuselage paneluntil there is only a slight gap. The hinge isnow centered on the fuselage panel andelevator. Remove the T-pins and snug theelevator against the fuselage panel. A gap of1/64” or less should be maintained betweenthe fuselage panel and elevator.

    4)Deflect the elevator and completelysaturate each hinge with thin C/A glue. Theelevator front surface should lightly contactthe fuselage during this procedure. Ideally,when the hinges are glued in place, a 1/64”gap or less will be maintained throughout thelengh of the elevator to the fuselage panel hingeline.

    Note: The hinge is constructed of a specialmaterial that allows the C/A to wick or penetrateand distribute throughout the hinge, securelybonding it to the wood structure of the fuselagepanel and rudder.

    5) Slide the vertical stabilizer back inplace. Using a triangle, check to ensure thatthe vertical stabilizer is aligned 90º to the hori-zontal stabilizer.

    When cutting through the covering to re-move it, cut with only enough pressure to

    only cut through the covering itself. Cuttinginto the balsa structure may weaken it.

    2) Slide the vertical stabilizer into the slotin the top of the fuselage. The rear edge ofthe stabilizer should be flush with the rear edgeof the fuselage and the lower rudder hingeshould engage the precut hinge slot in thelower fuselage. The bottom edge of the stabi-lizer should also be firmly pushed against thetop of the horizontal stabilizer.

    3) While holding the vertical stabilizerfirmly in place, use a pen and draw a line oneach side of the vertical stabilizer where itmeets the top of the fuselage.

    BALANCING. 1) It is critical that your airplane bebalanced correctly. Improper balance willcause your plane to lose control and crash.THE CENTER OF GRAVITY IS LOCATED110 MM BACK FROM THE LEADING EDGEOF THE WING AT THE WING ROOT.

    3) Turn the airplane upside down. Placeyour fingers on the masking tape and carefullylift the plane .

    2) Mount the wing to the fuselage. Using acouple of pieces of masking tape, place themon the top side of the wing 110 mm back fromthe leading edge of the wing at the wing root.

    Accurately mark the balance point on the topof the wing on both sides of the fuselage. Thebalance point is located 110 mm back fromthe leading edge of the wing at the wing root.This is the balance point at which your modelshould balance for your first flights. Later, youmay wish to experiment by shifting the balanceup to 10mm forward or back to change theflying characteristics. Moving the balanceforward may improve the smoothness andarrow- like tracking, but it may then requiremore speed for take off and make it moredifficult to slow down for landing. Moving thebalance aft makes the model more agile witha lighter and snappier ”feel”. In any case,pleasestart at the location we recommend .

    *If possible, first attempt to balance the modelby changing the position of the receiver batteryand receiver. If you are unable to obtain goodbalance by doing so, then it will be necessaryto add weight to the nose or tail to achieve theproper balance point.

    With the wing attached to the fuselage, allparts of the model installed ( ready to fly), andempty fuel tanks, hold the model at the markedbalance point with the stabilizer level.Lift the model. If the tail drops when you lift,the model is “tail heavy” and you must addweight* to the nose. If the nose drops, it is“nose heavy” and you must add weight* to thetail to balance.

    CONTROL THROWS.

    Aileron: 1-inch(15 )up. 1 5/8-inch(23 )up. 1-inch(15 )down. 1 5/8-inch(23 )down.Elevator: 1-inch(14 )up. 2-inch(25 )up. 1-inch(14 )down. 2-inch(25 )down.Rudder: 1 3/4-inch(18 )left. 2-inch(22 )left. 1 3/4-inch(18 )right. 2-inch(22 )right.

    Low rate High rate

    Note: Control throws are measured at the widestpast of the elevator,rudder,and aileron unless notedotherwise.

    Use the following throws for 3D aerobatics:Aileron: 2 1/2-inch(35 )up 2 1/2-inch(35 )down.Elevator: 2 3/4-inch(35 )up 2 3/4-inch(35 )down.Rudder: 2 1/2-inch(28 )right 2 1/2-inch(28 )left.

    D) Check the throttle. Moving thethrottle stick forward should open the carbu-retor barrel. If it does not, flip the servo re-versing switch on your transmitter to changethe direction. E) From behind the airplane, look atthe aileron on the right wing half. Move theaileron stick to the right. The right aileronshould move up and the other aileron shouldmove down. If it does not, flip the servo re-versing switch on your transmitter to changethe direction.

    C) Check the rudder. Looking frombehind the airplane, move the rudder stick tothe right. The rudder should move to the right.If it does not, flip the servo reversing switch onyour transmitter to change the direction.

    A) Plug in your radio system per themanufacturer's instructions and turn every-thing on.

    Check the operation and direction of theelevator, rudder, ailerons and throttle.

    FLIGHT PREPARATION.

    7) Check the receiver antenna. It shouldbe fully extended and not coiled up inside thefuselage.

    3) Double check the balance of the air-plane. Do this with the fuel tank empty.

    5) If your radio transmitter is equippedwith dual rate switches double check that theyare on the low rate setting for your first fewflights.

    2) Check every bolt and every glue jointin the SEAGULL FUNFLY 3D to ensure that everything is tight and well bonded.

    6) Check to ensure the control surfacesare moving the proper amount for both lowand high rate settings.

    1) Completely charge your transmitterand receiver batteries before your first day offlying.

    8) Properly balance the propeller. An outof balance propeller will cause excessive vi-bration which could lead to engine and/or air-frame failure.

    PREFLIGHT CHECK.

    B) Check the elevator first. Pull backon the elevator stick. The elevator halvesshould move up. If it they do not, flip the servoreversing switch on your transmitter to changethe direction.

    4) Check the control surfaces. All shouldmove in the correct direction and not bind inany way.

    We wish you many safe and enjoyableflights with your SEAGULL FUNFLY 3D.
