Exceed-RC 1/10 2.4Ghz Hyper Speed Beginner Version .18 Engine Nitro Powered Off Road
 

I'm having an issue with this thing where it burned the 1 speed plastic transmission out. I was at work running it.(I work on a military base), and some signal got ahold of it and took it full speed towards a curb. This burned out the plastic one speed transmission. I'm looking to either put a two speed in it, or put a metal one speed into it. Instead of the plastic thing they had in there. Can anybody help me? I'll be able to upload a photo after I get my other device signed into the site. Thank you guys for any help.
