Today I was practising ahead of my PfCO at the weekend. I have set the P4 RTH altitude to 30m, plenty for the area where I am operating. When I initiated the RTH the P4 yawed and stabilised in the corrected heading and then ascended to the RTH altitude, but it continued to ascend beyond the RTH altitude and I had to intervene and cancel the RTH procedure.
Has anyone else encountered this issue with the P4 and if so what was the fix?
I will be heading back out tomorrow to do some more flight tests before I head off at the weekend to do my PfCO.
