Tail slip?

[Reaper2674]

This is with an older 3g flybarless system,Every time I push hard positive pitch on my 600n in idle up to go into a flip or roll the tail drifts on me??? Like it's not staying locked in.. It flew fine last year and all of a sudden its acting up! At first all the cyclic controls were extra sensitive in idle up only and I fixed that by putting more cushion under the gyro sensor but now I've got the tail issue and there is nothing for Q&A in the manual about the tail wandering with quick cyclic inputs.. Its stays locked in if I scale fly the thing but that's not how I fly!!!!

I working on similar problem on 450l 3gx. I think my esc internal bec (with one damage condensor) cannot supply voltage during hard maneuver. I currently rebuilt it and try to install a glitch buster(external condensor). if your not running servo between 5.5- 6.0 volt try to raise it
