FAQs
Q:
Why is the flight control red light flashing and the software prompt compass abnormal after connecting
the line and inserting the computer for adjusting?
A：
Because the compass is not calibrated or the calibration is unsuccessful, the flight control red light flashes
slowly. Please move the speaker and other magnetic objects out of the room, and re-calibrate the compass.
After the calibration, disconnect the battery and USB cable, and dial to 3D to display blue.
Q：
Software prompt 3 channel throttle value is too low, how to do?
A：
This is caused by the large range of 3 channels of the transmitter. You can enter the transmitter settings page
to reduce the maximum and minimum value of 1-4 channels and reduce the range. After adjusting the
range of the transmitter, the rocker needs to be re-calibrated.
Q：
Software prompt GPS connection abnormal, how to do?
A ： Check whether the GPS plug is loose, and whether the wire comes off or damaged from the buckle. If it is
damaged, replace the wire.
Q：When adjusting, what to do without negative pitch?
A：Please set the mode switch of the transmitter to the 3D and re adjust the positive and negative screw pitch. If
necessary, remove the servo arm, click zero pitch, re-install the servo arm, adjust the pitch lever to make the
aircraft pitch zero, and then adjust the positive and negative pitch.
Q：Why doesn't the swash plate servo move? Only the tail servo moves?
A ： This kind of flight control is in GPS mode or automatic flight mode (controlled by 5-channel and 8-channel
switch), and the swash plate servo does not move. Only when the 5-channel mode switch is switched to 3D
mode, the swash plate steering gear will move.
Q：Why is the flight control not corrected after the correct adjusting?
A：The swash plate is completely locked before unlocking take-off. As long as the correct adjustment is carried
out according to the specified steps, the flight control will be automatically correct.
Q：I removed the blades and run the helicopter to test , why can’t do that？
A：The flight control has take-off detection (with propeller detection). It is invalid to run it on the table without the
blade. Either the servo does not move or it moves randomly.
Q： Should I set the stop switch on my transmitter？
A：No need, the flight controller thinks that your 3 channels are pitch control and 7 channels are motor control. If
you cut down the 3 channels, the collective pitch becomes -12 degrees and the lock is completely locked.
Unable to fly, or directly hit the ground (the flight controller does not read the 6 channel value, this is invalid).
Q：Why can’t I run the helicopter? Turn the stop switch, the motor does not turn？
A：Because this is a flight controller, you need to unlock the outer eight before you can dial the motor start switch
(before unlocking, you must ensure that the motor switch is in the stop position to unlock. After the unlock
flashes, dial the run switch and the motor will turn) .
