RE: Skymaster F-4E phantom
Bob,
I have 2-5 cell nimh going to a Powerbox, and 1-6 cell for the ECU installed all the way to the front of the "E" nose. Balanced at 285mm back from leading edge. After flying for the past month I'm going to switch the ECU to LIth Ion 4 cell to reduce weight and move cg back a little further.
