Yeah, the controller really isn't in the best place, is it? I have some servo tape as padding on the back of it, but I think I am going to make a mount to mount it over the motor in the future. As for the Maxamps packs, I hope they won't! I'm going to be running with a Li-Saver, so I'll just have to be careful. I have some 25c 5000mah lipos coming soon, so they should be able to handle it better, no?
