Quadplane drifts in QLOITER, QRTL and QLAND modes

ArduPlane Plane 4.3

Hi all, so we have quadplane that flew today without any issues except when it transitioned into QRTL. We noticed the vehicle drifting from the home position. We changed to QLOITER to have some manual control and return it above home position but it drifted further. We changed the mode to QRTL again and the vehicle flew back above the home position. We finally changed to QLAND and the drifting occurred again till the vehicle moved into a tree and was disarmed. The drifting was smooth and seemed controlled. The vehicle is a Yangda FW320 quadplane Logs are found here. @tridge @Yuri_Rage @Jan_Kryca

Hey @kwasi ,

I have already looked at the log - I do not understand why it is drifting. The GPS modules look healthy, and all behaviour looks fine other than this drifting that we can see.

Could it be that the GPS modules are appearing “healthy” but in fact showing a slightly wrong position / drifting?

Hey all
Did your drifting problem resolve?
Even I’m facing the same issue as yours.
