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 benötigt!
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 won’t 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 shouldn’t 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“.

Checking the rotation direction
Now you can activate the fixed motors with a click on each button from “M1” to “M4“.
In case the rotation direction is different from the displayed image in the Assistant, simply swap 2 of the 3 motor
cables.

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 doesn’t point upwards or downwards and that
the cables can’t 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.
