Running the new beta today with a fresh install reset all and started from vanilla. Stock gains seem high and got some twitch not sure if that was changed if so bad idea in my camp. However a quick slider to less twitchy had it stable in 3 mins. GPS hold is nice and we have perfect flying today.

Thanks to the Devs!

2 Likes Hi Randy I been doing some testing in Realflight and I am noticing that the Yaw authority seem to be sloppy now and can’t be tuned our with VTOL-Quicktune.

Has there been any changes to the stock PID’s over the last month or two? if so please let me know how to bypass this change. Basically I see a lot of overshoot to a relay nice old model performance in Yaw.

I get the same Yaw overshoot in Plane and copter now.

Looks like dropbox in now longer working.

Hi @Quadzilla,

Thanks very much for testing!

I don’t think there have been any changes in the yaw control in 4.4 vs 4.3. Even 4.5’s yaw control hasn’t changed I think.

Thanks odd. I did notice some yaw rotation in the realworld test yesterday. but it smoothed
out right away.


Hi, Randy,
I think i can see what going on loiter seems to be breaking in standard Yaw meaning the same breaking when you go right to left is now in position yaw GPS Loiter mode standing still rotation. No wiggle in 4.3.4 so i believe this is an issue.

My Testing in Realflight also shows the same odd correction.

Update: turns out my Flight controller was loose again! All well in Yaw sorry my bad.
