Didn’t have this issue before installing the FPV system. The movement with just the H3-3D gimbal and Anti Interference Board was absolutely fluid and constantly smooth. Now I have terrible full frame jittery and jumpy random movement. Link below illustrates. http://youtu.be/acrCtbqkvrY New FPV equipment - Black Pearl Flysight diversity Monitor - DJI FPV Hub kit - ALV58 transmitter (Belly mounted with thick velcro as far away from the compass as possible as advised by DJI’s web site) - iOSD mini (Belly mounted with thick velcro next to the AVL58) Here's what I've done to trouble shoot: - Made sure nothing was touching full movement of gimbal (Parts, ribbon cables, velcro etc.) - Calibrated compass and checked IMU - Advanced compass calibration - I've calibrated the controller in the RC and PT2 software - Rechecked my advanced gimbal settings, limits, gain etc. in PT2 software - Checked for all firmware updates - Calibrated X1 channel in the RC and PT2 software. - Tried a different Hero 4 camera - Counter balanced gimbal to compensate for Hero 4’s added weight compared to the Hero 3+ - Inspected the gimbal motors while powered on for resistance, odd sounds, debris and dirt. - Factory Reset gimbal and re-uploaded firmware - Opened up Phantom and checked Anti Interference Board connections – Looked fine. Some may view the movement as subtle and no problem but to me it’s enough to completely ruin a shot. The movements are too violent for something like Warp Stabilize to fix in post. Any suggestions and/or recommendations are most welcome.
