Opened throttle closed it had no effect whatsoever still at full tilt. Phoned engineering who said shut it down . Restarted with no problem. Engineering had another 3 days later do the same thing. Apparently the Fadec thinks the battery is flat so It will wind up to full rpm to charge up the battery. I m not sure this is correct as to why would anyone design the system to do that on a remote start ??? Answers on a post card.
I have heard something similar - apparently if you connect ground power without the battery connected you will get similar results. It will start itself OK and go straight to FLY when you pull the ground power plug.

Probably makes sense when you think about it but can be a trap.
