Chuck, don't you have to regulate them. 7.2 nominal may be to much for the servos and receiver. I don't know what the fully charged voltage will be. I've been looking at them also. I've got a 33% that has batteries in it, but I'm not sure what they are, I just got the plane and haven't stripped it yet. I know that there is at least three packs in it. 'll probably put in a distribution setup with a regulator, of some kind.

The other plane I got from the same guy is a 1/4 scale with some monster 4.8V 1200mah packs from Airtronics. They look like sub C cells. They will go and I'll replace them with some 6VNiMh 2300mah packs or similuar. I want the extra torque from the 6V packs. The four main servos are JR 8101's in this guy.

Don.
