Been having an issue when bursting with right yaw, some of my esc's would flash yellow (see video). I played with my gains and they have seemed to disappear. But when doing a simple pan back maneuver (quarter stick backwards) 2 or 3 of my esc's turn yellow for a good second or two and my craft J turned backwards/ yawed to the left, see attached clipped. Second clip in attached video.



I don't see how doing simple maneuvers will cause the motors to spin at full speed?

jbjoshb, also what controller are you using?  What are your gains on that controller?  I have not seen that behavior on my S900 with A2/Lightbridge/iOSD MK II/ Zen with BMPCC.

Hi, jbjoshb, I suggest calibrate the remote controller again to see whether the issue persists.

According to the manual, yellow is an indication that the ESC has reached the maximum power output. Your aircraft is on the edge of being too heavy. Your gains seem to be a bit high too.

Correct as CG stated.. my question is why are you hitting full throttle? What altitude are you flying at? I fly the identical setup and have tons of power left at 7000'.

There's no problem if it flash yellow. just for let you know that the ESC is outputting a full power. this always happen if you want to make a big move, like yaw, roll, pitch, the bigger your gain is, the frequently it happen. when you turn yaw, half of the motors accelerate, half slow down.
