Tricopter pre-arm tilt motor angle

[urlu75 (lulu)]

Had a similar issue with my tricoper. The workaround I found is to set SERVO_BLH_AUTO=0 but it seems it’s already the case for you.

TriCopter tail servo servo_trim always reset

I changed the motor output to respect the group order. 1,2 & 6 are now motor and 3 is servo tail. When SERVO_BLH_AUTO=1, whatever is the motor output, SERVO_TRIM is reset to SERVO_MIN at boot time. My esc are blheli but not blheli_32 and are not dshot compliant, don’t if it could be the reason why. MOT_PWM_TYPE=0 and I tried with SERVO_BLH_OTYPE=0 and 2. So unless I misunderstood something, tricopter is not flyable when SERVO_BLH_AUTO=1 with my setup/gear.
