Fixing Tail Wag

Hey all,

I have a Parkzone Icon A5 that I’ve outfitted with a PixHawk, and I have to admit it makes an awesome little drone platform.

One of the known issues with the PZ IA5 is excessive tail wag/oscillations at high speed and low prop RPM (very evident when coming in for a hot landing). I suspect it has to do with the wide body of the airframe disturbing laminar airflow over the tail when the prop isn’t pushing air over it. Anyway, I know others have fixed this by installing a tail gyro (like on heli’s) but I’m wondering if this could be solved with the APM:Plane?

I’ve noticed in FBW modes that roll and pitch seem to be stabilized, but I’ve never noticed the APM use the rudder to cancel out yaw movement. Is there a way to enable this?

Any help would be greatly appreciated. Thanks!

Look up Yaw Damper in the wiki.

Thanks iskess. I’ve seen that discussed before in the wiki, but it seemed like what I was reading said it was only useful or active when the plane was in a bank/turning situation. I guess I’ll just have to try it. Will let you know if it solves the problem.

Read through it again. Yaw Damper and Rudder Mix are different.
You will find instructions in the tuning guide under yaw.
