Default Sudden Drift in Stability Mode

So in 3D and Intermediate mode this heli flies great and is trimmed very well. I can do hands off for about 10 seconds in calm wind. But as soon as I switch it to Stability mode it shifts rearward. It is almost to the point that I can not stop it, mostly being the controls are so weak in that mode. I'm really not sure what to do, the setup is great. Its the auto leveling that is off. Any ideas?

Default In my experience......

your new 250 needs a trim flight.This procedure will resolve the drifting.

If you don't have a drift issue in non stability modes, the servos should already be at 0 pitch so that shouldn't be an issue. Do a trim and report back.

Could also be due to Heli not been level when you connect the battery.
Always have it level when you first connect up.

It's fixed! I ended up doing a trim flight, then a calibration, and then another trim flight as the manual suggested. I didn't fly in stability mode until after the second trim flight, so im not sure if it was really needed. But it perfectly self levels now. Thanks guys!

Done properly, the trim flight does solve many issue relatively easily.

If you find that the drift has returned on your next outing, a little quirk that is not mentioned in the manual is that it will not save the data if you complete the trim flight and turn on THROTTLE HOLD. Once complete, throttle down in stability mode and safely disconnect the battery to save the data. Once saved, you can use throttle hold normally during/after your flights.

Hmm maybe I did that on the first one. But on the second trim flight right after the calibration I saw the swash plate twitch, indicating it saved the settings.

Thanks for the tips.
