5. Observe whether all propellers spin freely to the right direction.
a) If not in the right direction, lower the throttle to minimum and power off copter. Reinstall propellers to
test again until it works in the right way.
b) If not in a smooth way, throttle down to lowest and power off copter. Check electronic circuit and motors
to retest until it goes well.
6. If every part works fine, and keeps the throttle at 20% and try to push stick slightly in Pitch, Roll and Yaw (stick
value 30%).Feel whether aircraft attempts to move to the corresponding direction.
7. If showing wrong direction to any of Pitch, Roll and Yaw, adjust signal cable connection order of receiver to
test again until it becomes normal.
8. Throttle back to lowest and power off copter.
3. Auto-leveling Test
After X650 Value stick function test on ground now it goes sensor test.
1. Unplug Flight Mode channel signal cable (default Input 5).
2. Throttle down to lowest then turn on the transmitter.
3. Power on copter.
4. Squat and grasp the bottom side of copter to lift it higher than your head.
5. Apply throttle slowly to 20%.
6. Try to use the aircraft forwards, backwards, left side and right side and feel it whether aircraft has stopped
your moving.
7. If no resistance, throttle down to lowest and power off copter. Check if electronic parts installs properly. (Like
AHRS installation orientation or good connection).Then test again.
8. If aircraft reacts perfect, throttle down to lowest and power off copter. Now you can start your first fly and
enjoy it.
FAQ of Flight
No reaction to the throttle control, motors do not start.
Check the problems as below.
1. Motor warning that not received any valid signal: Normal ESC is used but configured as UltraPWM ESC.
2. System light of FC1212-P is flashing faster: throttle protection, use throttle subtrim to adjust the minimum
throttle down a bit then try again. If problem is still not solved, connect to XAircraft Center to do the Rev Test
and calibration.
Flap over when taking off
1. Check if the propellers installation error or not.
2. Check if the direction of AHRS or Compass is correct.
