Hi guys

Not had my 250 out much lately but have a issue. Was running version before latest two updates 15. Or something. Everything is good. Good low down stick response even with slight expo added. Since the update to black rhino I don't get very good control. There is expo added but no more than before.

Is there something I've missed? Another new setting

When I updated I did a screen shot of rates etc. Then did a clean install. So config should be good. I haven't tried to remove complete expo. But I can't see that being a problem. Or is it

Cheers
Paul

Are you saying that control at low throttle is not as good?  Maybe needs PID tuning or TPA?

[paul0]

Nope throttle is all good. Good power just roll. Pitch and jaw no real input until 40 percent throw. Like expo but tbh it's very flat so worse

It may be that you have a deadband set too high or maybe extreme expo in the transmitter settings?

[paul0]

I'm sure deadband is 0 and expo on control isn't set. There is expo on the settings on quad. But it's just what I had set on older firmware.

If I flashed older firmware and used identical settings it would lean and yaw a little with slight stick movement but won't on latest firmware. It's strange.

I did try version before black rhino but had issues like this and just rolled back without issues but I can't use always stabilised as option isn't possible.

Forgot to say I'm using cc3d flight board without baro just gyros

Using 16.09 you should set half value from 15.09 for similar expo behavior, as mentioned in Notes here :

Aha that's what you get when you don't read release notes very well.

I will try with no expo.

Thank you for clearing that up
