When you turn off the transmitter, use the following method to regain control: (1) Switch the transmitter FMD
switch to GPS Atti. position. (2) and then put the throttle stick to lowest position, you can now turn the transmitter
back on (greater than 5secs after switching off, important), then put throttle stick to the center position
immediately. If you hear the transmitter alarm, make sure the throttle stick is at the bottom position before moving
to the center position. (3) then you can switch the transmitter FMD switch to the middle position (ATTI. Mode) to
regain control.
Note: if you start the motors, but do not push the throttle to take-off the aircraft, in this case it is very dangerous to
turn off the transmitter, because the aircraft will take off automatically, so do not try this.
* If signal lost for more than 3 seconds failsafe will be triggered, if signal regained within 3 seconds it will exit failsafe
immediately.
