Ok, so you probably have heard this a million times...I've been flying glow for about 5yrs now and am interested in getting into 3D electric planes. I'm thinking about the Free Air Extra 3D, and getting the Rotex power package with it. What would be the best battery for this motor? says it comes with a 3cell 700mah Kokam li-poly..they also have available a 2 or 3 cell 1500mah, a 3 cell 830mah, and a 3 cell 1300mah, what is the difference between them? anyone have experience with any of these setups?

thanks,
rob o'
