dumb mistake...can u help?

[stealthboy]

Hey, I know there's lots of smart ppl on here, so i figured it couldnt hurt to ask a really dumb question. Well, the other night at about 4 a.m., i finished my 6 cell mod, and was about to test it with my spinbrush motor...and i put the batteries in backwards. very dumb mistake, i know... i didnt realize they were backwards until i turned on the car and the control, and tried to drive it. when nothing happened, i turned it off, opened it, and saw the problem. my question is this: is there any way to save it? i'd like to think i might be able to replace some parts rather than have a very pretty 50 dollar model sitting on my shelf... if anybody knows of anything simliar to this happening and it coming back to life, that would be great. if not, thanks for reading this at least!
