Step 1: Assemble wing and arm
①As the picture show, you can see the leading edge of the wing is bending, the rearing edge is more flat. Wing
root
side is wider than wing tip side. In this way, you can find the right direction to assemble.
②Connect VTOL motors
Caution: Wrong connect of the motors could cause crash when takeoff!
Please double check carefully after connected.

V. Flight Control Tuning
Flight control tuning is very important for a good flight, because tuning involves a lot of flight control parameters, such as TECS, PID,
inner loop control, outer loop control, Angle, speed, etc. Each aircraft has different adaptive parameters.
VI. Pre-flight Inspection
The aircraft is well configured and debugged, can be used directly for flight missions. Due to the difference in the earth's magnetic
field environment, you may need to re-calibrate the magnetic compass.
Note: Under no circumstances should the electronic compass be near magnets or areas with strong magnetic fields. Otherwise,
the electronic compass will be damaged and the aircraft will be abnormal or even out of control.
When is calibration required?
After updating the firmware, before the first flight.
When arriving at a new site far away from the original flight site (such as across states and cities).
The aircraft drifts or the hovering not stable.
Note:
Do not carry magnetic devices (such as mobile phones, keys, etc) during calibration.
Do not perform calibration in places with strong magnet, such as parking lots, building areas with steel bars, etc.
During the calibration process, please make sure the aircraft rotates horizontally or vertically.
Keep away from magnetic materials and other electronic equipment during the calibration process. Choose an open area without
high-rise buildings and strong magnetic fields. Before calibration, reconfirm the aircraft is placed on a flat surface and take away the
electronic devices.
1. Calibrate compass
Calibrate the compass every time to a new place.
Setup→Mandatory hardware→compass→start
Usually we only open external compass, if you use two compass you should set external compass with the most prior.
Click start then hold the aircraft and rotate it in six directions: horizontal, left, right, up, down and back until the ground station
shows that the calibration is successful.

11 of 18
Please correspond to the positions of the plane above, and then turn the plane. Each axis requires one circle of the airplane. When
the ground station progress bar reaches 100%. The calibration is completed.
After the compass calibration is completed, place the aircraft horizontally and wait for the flight control system to restart
automatically.
Note:
If the ground station prompts that the calibration has not passed, you need to re-calibrate. If the calibration fails several
times, it is recommended to change the location and re-calibrate.
This aircraft uses Mission planner for configuration. It is recommended to use Mission Planner software for sensor
calibration and configuration changes.
2. In FBWA mode, the aircraft should look up and down, and observe the feedback of the tail rudder surface of the aircraft. The tail
rudder should swing down when looking up, and the tail rudder should turn up when looking down
3. In FBWA mode, the remote control controls the rudder to observe the change of the plane's rudder surface.Left stroke, aileron
left high and right low; Right stroke, aileron left low and right high; Push rod tail rudder downward; Pull rod rudder up.

6. In the quick interface, check whether the battery voltage, airspeed, altitude and flight mode are normal
7. Ensure that no error is reported on HUD interface
8. Balance Center Gravity: Lift these two points to ensure that the aircraft is balanced (there is a slight forward inclination within
5 °). If it is unbalanced, the center of gravity needs to be adjusted
VII. Flight route planning

13 of 18
1. In PLAN interface ,create your flight plan,Choose relative height.
2. The first point must be set VTOL_TAKEOFF. The altitude should be set according to the surrounding environment
3. The distance from the first point to the second point should be between 150 and 200 meter
4. The last point we usually set return_to_launch,Because we set q_rtl_mode=1 in flight control parameter
5. When the route is drawn,Click Write
6. Right mouse click,click clear mission
7. Then click Read
