I'm not talking about slight shifting as the voltage drops. Rather it seems like the trim will radically shift from one flight to the next. Sometimes full left trim, sometimes neutral. I'll stop and fiddle w/ the propo and gain, it will work for a bit, then change again.

Weird thing is sometimes gyro gain seems locked in, then the tail will develop that bizzare twiching thing.

This is starting to get me PO'd.

running dual tail motors, plasticblades, and 1300mA Lipo.

anyone else notice this trimming issue?
