I crashed my trusty phantom 2 today trying to do a manual flip. So thats right stick all the way over in a single direction and backing off the power at the right point so it can rotate round rather than make a bigger turning circle I think. It didnt work and by the time my 20m height became 10 as I got into GPS mode it was never going to be able to recover. In short I crashed doing something stupid and I have paid a price. At this point it isn't clear how much.
There is a connector (PCB interface) inside that was rattling around the EXP one and this doesn't seem to be used and may not be an issue. The other is stopping the show. A SMB connector from the battery is the clue and I have found out its the Smart Battery Connector - even connecting the USB and running the software on my mac shows this to be a fault.
Here are a couple of photos of the Phantom 2.
