not, there is no minimum throttle in AUTO2. You can hack main_ap.c (line 589), replacing

    ap_state->commands[COMMAND_THROTTLE] = v_ctl_throttle_slewed;


ap_state->commands[COMMAND_THROTTLE] = Min(MAX_PPRZ * MY_MIN_AUTO2_THROTTLE, v_ctl_throttle_slewed)

I have a hard time keeping the plane flying in a very difficult place due to strong and very very

Thermals are so strong that can crash the plane easily.
Yesterday i fell in to a microburst that was there for 2 or 3 minutes and then vanished. I almost lost the plane as it was sucked down at full throttle in MANUAL mode. Imagine seeing a plane flying straight at 60 -70 meters and suddenly losing 50 meters without changing attitude, it just sunk and everybody there said that they have never experienced something like that again.
Is there any way to increase the minimum throttle in auto2?
I just don't want the plane to fly with anything lower than 60% throttle except
when descending.
