VTOL keep on increasing speed after take off

For some strange reason, after transition, the aircraft keep on increasing speed and starts to loose altitude. I cannot find the root cause. Please help


@tridge Sorry to bother you. I have been trying to find what happened, but it seems the autopilot missed the transition and keep on increasing the speed. Can you please have a look?

Edit: I think we found the problem. Luckily the VTOL landed safely (no crash) and we checked all the wiring. It seems the elevator connector was intermittent.

glad you found it! That sort of thing can be very difficult to track down
