My Align 450 Pro FBL is powered by APM2.6 using Arducopter V3.2.1.
Do I do auto tune according to the procedure set out in Wiki, same as that for multicopter ?
For mid throttle setting, since the throttle is now controlled by a knob and the throttle stick controls the collective, how do I set the mid throttle for hovering ?
Appreciate any help.
Assuming you could get autotune to engage with a helicopter, I would not recommend it. I’m pretty sure the result would be an instant and quite impressive crash.
The collective curve for a helicopter is set with the params
IM_STAB_COL_1
IM_STAB_COL_2
IM_STAB_COL_3
IM_STAB_COL_4
The range for those params is 0 (max negative collective pitch) to 1000 (max positive collective pitch) in 3.3 and on. I do not know if the scaling was the same in 3.2. The 2 and 3 numbered params correspond to the lower and upper “deadzone” of the collective in Alt Hold or Loiter.
