Hi mrasmm, I am using the stock lipo battery that comes with the cp pro and the stock motor with the 9T pinion. I have taken the heli apart lots so lube is not a problem and I did not notice any signs of a short on the main motor wires when I finally got around to doing the fuse mod tonite. The motors do not feel that hot after a flight but I do use two heatsinks on both motors. I confess I have not broke in the motors as per the forums so maybe thats causing a problem. Also I guess what I can be noticeing with the flight times is a progression from stock heli with training gear and flybar weights to adding superskids and then to adding the plasti-blades. I haven't really accurately kept track of the time more or less a glance of my wistwatch and an observation I have noticed. Thanks Rick
