Try lowering your yaw P and I gains.

+1 If you change props, you have to review your gains.

ok thanks, will do. my yaw gains are quiet high if i remember correctly. cant test it now as the kids are in bed, but will try it in the morning and report back.

if you don't mind me asking, how would the yaw gains, high or otherwise, affect the throttle? not disputing your advice, i genuinely don't know how high yaw gain's would produce the symptoms evident on my throttle control.

if your doing the KK patch on your 1.4 Acro firmware I'll install it and try but were in for 4 day's of rain so it might take some time.

This is from the PI tuning guide:

Yaw P-tuning

Increase Yaw P-gain by 10 (5 or less for a small aircraft) at a time, and test your aircraft response by hovering and move the Yaw control stick until it have yawed about a quarter of a circle, and then center it.

As you increase the gain you will notice:
1: The aircraft start and stops faster.
2: The aircraft overshoots less.
3: The aircraft may start to climb or descend.

I might try it myself this weekend. If I notice a big improvement I will certainly let you know ASAP, but otherwise I think we should wait a few days and see what Rolf comes up with.

ah yeah,i remember reading that now, thanks. think i might go back to factory and start over. having those crappy red brick esc's on there meant i had to keep my gains really really low,and it still didn't stop the shakes. now i have better esc's i think i may of got a bit carried away with my gains i will have another crack at it in the morning with fresh eyes.

I will record my 10" settings and try adjusting for 8" tomorrow. I may just factory reset and retune all together for 8". I will report back sometime this weekend.

the more I think about it I'm sure he's correcting the error as we think about it. But if nothing shows on LazyZero's update list I'd for sure try your updated firmware.

Very nice video Trinco. What camera are you using for AP?

I've never had any luck with height damping. Mine is alway at 0. Anything else the quad would do random things.

thanks, nothing fancy just gopro

I think what happens is that the overshoot on correction causes the craft to use too much total thrust per unit time and the excess becomes general lift. At least thats how I envision it in my head.

I have seen your laps in the park. You sir are one hell of a pilot.

To me high P and I gains won't affect altitude. If you PI is too high it will oscillate, but not gain altitude. Height dampening is the only thing I have ever seen raise my quads altitude, it acts possessed at anything more than zero.

Surprised. That does not look like GoPro video - no spherical distortion.
