Heavily oscillating RCOut for motor 5 and 6 on large Hexa

I have some strange behavior with my new build T960 on 3.3 RC4: Large oscillations on RCout but only on RCO5 and a bit less on RCO6 which suddenly stopped in this log. I am using Arris 5010 12 pole and BLHeli 13.2 with nearly stock settings (PWM high, Timing medium). I think its a timing issue of the esc to the motor, but why are only two motors affected? Maybe someone can give a tip?CheersGregorSee More
