So... I've had my H3-3D for about two months now and have around 15 flights on it with no issues at all. Today I went flying... at altitude and at a relatively fast forward speed, the gimbal will occasionally jerk left to the point where I can see the landing gear (and I have the aftermarket wide and tall gear) for about 3 seconds, then straighten out. It did this about 5 times during a 15 minute flight. Now, when I'm down low and slow, it doesn't do it! When I first noticed it, I starting troubleshooting in the air to see which flight conditions induced it. Sure enough... only when I'm going full bore forward. Seems more pronounced when I'm in atti mode going fast forward. Not so much in GPS mode with the slower speed. This has me stumped! Besides doing an IMU advanced cal, anyone have any ideas what could be causing this??
