Forgive me for questioning, but the ground clearance doesn't look to be any better on the RC 10 than any of the buggies, and it does just fine for bashing around.

I looked through Tower's buggies, and I didn't see any that didn't come with an engine, a radio, or both. Where can I find just the unassembled kits?

Are Mugens any good? How 'bout Ofna?
