It's exactly like these guys say. I flew my GWS A-10 for the first time on Tuesday. One of the packs was right out of the wrapper, on the fast charger, and in to the plane. I had a heck of a time staying off of the ground, espeically in the wind. The second flight was a bit better, I expect the 3rd will be better still. I think I read somewhere that Nicads hit peak on the 4th cycle.
