Assembly of the booms

In the kit, booms with 2 different lengths are included. The shorter booms have to be mounted to the front end of the aircraft. Before mounting the motors, please make sure that the threads for the motor wires point to the center frame. When you finally tighten all screws, you will have to fine-adjust the rotation of the boom.

The mounting holes for the landing skids have to face down.

Nicht im Lieferumfang M3x15mm Distanzbolzen

am besten aus Metall. Werden bei H3-3D Gimbal bentigt!

Make sure that the asymmetrical holes in the motor plate match the threads in the motor

before you insert the cables.

Do not tighten the screws firmly already. You will have to loosen them again when you adjust the vertical alignment of the motor axis.

First, you have to thread the motor cables through the whole length of the boom. Then you have to bend the cables

back and thread them through the holes on the side using a pair of angled tweezers.

Please use heat shrink tube to protect the motor cables from the sharp edges. Avoid heating up the boom material!

Push the end cap into the tube before you attach the motor.

Installation of the ESCs, Naza V2 PMU and Zenmuse GCU in the frame and soldering of the y-leads

Please mount the ESCs and the ESC wires like shown in the picture. The cable tie holds both ESC and the wires on the

mounting plate.

In this position, the folding mechanism can work unobstructedly and wont damage the wires. The wires are almost

at the turning point of the boom, so they are protected from getting weaker or worn. If you mount the ESCs in a

different way, you risk damaging the wires!

Before you solder the cable harness, you should test fit the components into the frame. Doing so, you can measure

the approximately required cable length und cut them.

Installation of the NAZA V2 MC and of the RC receiver in the frame

- Before you install the receiver and the NAZA V2, you can connect them with the cable/s to get an

impression of the possible distance and where the receiver could be mounted.

At this point, you have to decide whether you would like to use a traditional receiver and connect each

channel directly, or whether you want to use a PPM receiver using only one cable with sum signal.

See the NAZA V2 wiring overview on page 6 of the English manual:

http://www.dji.com/product/naza-m-v2/download

- When mounting the NAZA V2, please make sure it is placed exactly in the middle of the frame and in the

CoG of the aircraft. The small arrow on the MC must point to the nose of the aircraft (to the gimbal) and

the line must be parallel to the middle axis of the main frame.

Checking the direction of the motor rotation Attach the booms including motors but without propellers to the frame and connect the three motor cables and the ESC signal cable.

The motors have to be fixed in upright position and there shouldnt be any loose objects around them.

Now it is time to adjust the first settings in the Assistant Software. The ideal power source is a regulated power supply unit with a current limit set to 3 amps.

Choose Basic Aircraft and then select QuadRotorX. In the following, please click the Motor Test button.

Confirm the warning message with agree.

Installation of the booms and closing the frame

The boom pipe should end exactly at the edge of the inner snapping part. When you adjust the vertical alignment of the motor axis, please turn the boom first until the cable holes are facing the ESCs. Make sure that the hole doesnt point upwards or downwards and that the cables cant get squeezed. After this, mount the landing gear and adjust the motor alignment using a 90 angled tool.

Before you fit the top frame plate on the side walls, make sure that the side walls fit snugly into the bottom plate and that no wires are squeezed. This process requires a bit patience.

Battery plate with H3-3D gimbal, GPS holder and battery plate extension for lightweight batteries (optional)

Please mount the snapping

parts and joints using the

following parts: 1 screw, 1

nut and 2 washers. The

washers have to be placed

on the outside of the

frame.

It is recommended to protect the GPS cable part which is threaded through the plate from damage with a piece of heat shrink tube.

The final position of the gimbal mount and of the battery plate extension can only be adjusted when the aircraft is fully assembled, so you only need to tighten the screws slightly at this point.

The arrow of the GPS antenna must point exactly to the front of the aircraft. Arrow and notch on the antenna have to be exactly parallel to the middle axis of the center frame.

Mount the battery plate to the frame using the rubber dampers, attach the gimbal and plug the cable in. You can also use the Anti Drop or cable ties to prevent the gimbal dampers from slipping out.

When the frame is closed, the CoG of the copter needs to be adjusted by moving the battery, battery extension plate

and the gimbal mount. Tighten all screws when you are finished.

From the mechanical point of view, the aircraft is now ready for the maiden flight.

The final step is to adjust the final settings in the Naza V2 Assistant software. You can find a screenshot of gain

values for reference at the end of this manual. Furthermore you have to enter the position of the GPS antenna, set

the low voltage values and RC transmitter switches. Please see the Naza V2 manual for further information.
