Taking off and landing
After model powered up and self-checking is finished, gently push
throttle to start motors, wait a moment for the motor to spool up the
speed. Push throttle till the propellers increase rotating speed but not
leave the ground, check whether model is drifting, correct it by
rudder fine adjustment. Push the throttle now till the model hover
and you can start the flight.
Keep hovering condition while landing, and pull down throttle slowly
till the model landed successfully. Taking off and landing features of

with helicopter model, T80 will be a simple to operate model.
Attention:
as affected by ground effect, airframe tilt phenomenon
may take place while taking off; use your rudder control to correct it.

Signal and forced landing
1)No signal protection:
no RC signal while starting up, model will enter
standby mode, red LED is blinking, and beeper with intermittent long
beep at the same time. Model will be out of standby protection status
when receiving reliable RC signal.
2) High throttle protection
: while powering up model, Radio throttle
stick is not in low level, model will enter throttle protection mode,
red, green LED will be blinking at the same time, beeper will have
“b-e-e-e-e-p” too, till throttle return to a low position, model will be
out of safety protection mode.
3)
Signal interrupt protection
: when model in operation, once RC signal
interrupt is detected, FC red LED will blink, beeper will beep a
moment at the same time, to warn user the RC signal is lost, if it is in
flying status, FC protection model will trigger force landing function
to land model automatically, during the force landing, beeper will
keep beeping. If signal recovered during landing, it will exit landing
process, continue normal flying.
Landing automatically can’t be less than 5sec, model will have
