finally got my turnigy multistar battery yesterday, and the big question is does it fit. well the answer is with slight modification yes. 1st of all I had to remove 2-3 mm off the bottom of the door openind to enable an easier entry. I decided not to go the connection 1st option as I have an led head light to connect. so I opened up the phantom and routed the power cable out the side.then with the battery in I removed the side of the door to route the cables. then heated up the door catch and bent it up to enable a tighter door lock. but it is still very tight so I think ill order a bigger battery door just to be sure. ill try and post some flight times later. I was getting 12-13 mins on the standard battery so we shall see.
