How much battery do I need?

I think that the L can motor will run hotter. It's going to have to work too hard. The XL can will have more torque and will handle gearing better. The 8XL, as far as I'm concerned, is a 4S motor. Running it on 5S will get you heat problems. If you want to run 5S, I'd go to a 10XL.

i just picked up some Neu 30c 5000 Mah Batteries from a buddy of mine and let me tell you... they fricking rock! and in my experiance max amps has some of the worst defect rates of any battery :( (well at least since i started working for a hobby store). granted im only running 4s in my kyosho but there soooo good :)
