I've been doing some auto mission tests with my Quadplane and using the hybrid RTL option at the end of the mission to land. The plane flies close to the landing point and then the vertical motors come on as expected. After this it's quite unstable and it even did two flat spins 360 degrees opposite directions before arriving over the landing point and then becoming quite stable during the final landing stage. I could use some help in how to correct this.
I think the flash file is truncated as I don't see any RTL towards the end and I did get a verbal warning about I/O heartbeat and logs towards the end of the flight.
