After adding all my parts into my P2 inlcuding iOSD, Datalink and FPV Tx, I noticed that after flight and during landing/idling on the ground, the motors start to slowly throttle up. At first I freaked as I though it was going to take off by itself so I cut the power to the motors. I started the motors back up and did a quick throttle up and landed again without issue but, it very slow started throttle up and eventually back down again. This seemed to happen several times before I cut power to the motors. The craft never took off by itself but, I've never seen that happen before until all my part were added. Anyone else experience this?
