➢ Assisted Takeoff
ALTHOLD/FENCE/ALTCTL: Push the throttle to enough power, after takeoff(throw it away), the
aircraft will climb to 20m automatically.
RTH Mode: Push the throttle to enough power, shake the aircraft or run, then the motor starts
slowly, and then take off after the power is enough(throw it away), the aircraft automatically
climbs and circles over HOME.
➢ Throttle control
MAN/STAB/ ALTHOLD: Throttle is direct controlled by RC.
FENCE: Before triggering RTH, the throttle is controlled by RC, after triggering, it is determined
by RTH.
RTH: Throttle is controlled by RC during assisted takeoff, after entering the circling state, the
throttle is controlled by the FC, it automatically adjusts the throttle according to the cruise
speed you set, you can manually push the throttle up (beyond the throttle calculated by the
FC) to increase cruise speed, but you can't pull it down.
ALTCTL: Throttle is controlled by RC during assisted takeoff.After the automatic climb to 20m,
the throttle is automatically controlled according to the cruise speed. When the throttle stick
is at the neutral postion, the flight is maintained at the cruise speed. Push the throttle up to
increase the cruise speed, and pull down the throttle to decrease the cruise speed; When the
roll or pitch stick is in motion, the throttle is manually controlled.
➢ Throttle output
Before executing
<Unlock the FC>
, there is no throttle output! After unlocking, throttle
output is determined by GPS status and flightmode.
NO GPS：After the FC is initialized and unlocked, the motor can be started in all
flightmodes!
With GPS：After the FC is initialized and unlocked, if the GPS is not fixed, only MANUAL
can start the motor. After fixed, the motor can be started manually except in RTH!
