So, let me get this straight, if the lipo battery can match the other batteries, and the CG doesn't change, then I can change the plug out and will have no problem as long as the motor and Rx will support the lipo? If all that is the case, can I get an adapter so I don't have to cut, splice and sauter the wire that is currently in the plane. That was actually my question, but thanks for the advice on the CG. I had not thought about that. As far as that goes, the lipo I have is just about the same size as the battery that was included with the plane when I bough it. Again, thank you for the valuable info.
