ok so maby go with the 11.1v lipo and a resistor to bring down the voltage? If I want to run a camera run with a lesser size lipo for weight, and if I want longer run times go for the biger one and ditch the camera? I really don't want to get too mutch into this one as its just a trainer for me and I'm dealing with very limited funds at the moment. I eventualy want to work my way up to a full sized electric, or maby an electric converted nitro (not sure if thats been done yet).
