I'd want to know if a 4s pack will fit under the upper deck,where the radio box and brake/throttle servo is now(with a 1940/7 or 1930/9 on the other side:027: ).You could cut it behind the steering and add a coventional rear brace brace but it'd be nice to keep it as a double deck chassis.
Nitro would be just for racing until I can get some lipos to run our 30 minute mains... Sometimes they even run 45...so lipos are a must. Just gotta save for em...
