Question: Why does my FPV video break up when I bank the wing?

Answer: Video break-up during banking is usually caused by the FPV camera or video transmitter (VTX) changing orientation relative to the receiver's antenna, leading to signal loss. When you bank the wing, the antenna polarisation can shift, reducing signal strength. To fix this, first check your antenna types; using circularly polarised antennas on both the transmitter and receiver helps maintain a stable signal during manoeuvres. Next, ensure your antennas are properly mounted and not blocked by carbon fibre or metal parts of the airframe. Try repositioning the receiver antenna to keep it clear of obstructions and maintain line of sight. Also, verify your VTX is running at an appropriate power level—too low can cause dropouts, too high can cause interference. Finally, check your wiring and connectors for any loose contacts. By optimising antenna choice, placement, and ensuring solid connections, you should see much less video break-up when banking your wing.
