i recently got a geat deal to get a kyosho alpha ten 4wd

the only thing wrong with it, when i push down on the starter box, only the flywheel spins. Its loose from the crankshaft i think. Is this a hard thing to fix? Expensive?

What are your thoughts on a kyosho alpha 10?
any flaws?
rants?
praises?

thanks
