4th flight done, and I've spotted a couple of issues. 1. Gimbal roll... it's hardly ever level! I calibrated the IMU on a spirit level (mod 0.00!) so I know it's good. I can manually adjust via the app but it doesn't stay levelled. 2. Yaw on forward pitch... my P3 seems to constantly yaw left when I pitch it forward. It's not a huge deal but it is annoying. Could this be tuned out somehow? Has anyone else noticed this?
