GPS S159 UAV – 2 seconds camera delay and early RTH, defective unit or normal?
Hi, I have a GPS S159 UAV (version with screen on the controller).
GPS lock is good (15–20 satellites), but the camera feed on the controller has about 2 seconds latency, even when hovering close (10–20 m). The drone also sometimes triggers RTH very early.
This happens without using a phone (screen is built into the controller).
Is this normal behavior for the S159, or does it indicate a defective transmission module?
