The twitch at startup is annoying, but the real issue is the in-flight turn to the left. That's infuriating!
Seems to me what is occurring is the wind force on the camera exceeds a maximum allowed force level, which causes the yaw servo to "hibernate" for a few seconds. Given the geometry of the gimbal, the wind always causes the gimbal to yaw left.
This conclusion is based on observing when, and when not, this behavior occurs. It always happens when flying forward into the wind, and is worse with camera facing forward (largest wind profile). Fly backwards and/or with the wind, or very slowly, virtually no occurrences.
The question is, is this a flaw in the servo, or firmware, or both? Can firmware be set to adjust the yaw servo to withstand greater force, without burning up the motor???
We H3-3D owners are beta testers, at our own expense. That does not sit well with me at all!
