Just a quick review for using the E-Sky LiPos (EK1-0180) on the Axe CP.

So far it's running really well. Since it's thinner than the stock battery, 1/16th inch of foam padding on either side of the LiPo will stabilize it; it also extends a little under an inch more than the stock battery. The LiPo is running longer than the stock NiMH batteries but I can't tell if I'm getting more power from the LiPos or not (I don't know how to measure that). At the end of a session, the battery is warm to the touch but the motor is pretty hot. Charging usually takes about 1.5 to 2 hours. Also, a Deans Micro to JST Male Adapter is required for this. You can get one from the link I posted above or you can get a [link=http://www.hobbypeople.net/gallery/625072.asp]Deans Battery to Speed Control Connection[/link], which I'm using.
