a, ok.
Here the promised logs. Baby tri with triflight 7b1 on a betaflightf3 board, no tailtune or connected servofeedbackwire. I did set servo min middle and max.
Just LOS flying with a few rolls and punch out, no forward flights. Sync video with log with +28.6 seconds.
I find that the tail servo twitches much more in triflight 0.7 beta, in with BF 3.7.1. I might try the servo lowpass.
The rolls stop beautifully, long live d term. Also the yaw authority without throttle is better than with BF.

If there is anything else I can do testing triflight on betaflightf3 board let me know.
