I was wondering how it all went with your conversion. I flexed my chassis and took out second gear on the spur,,, did you have those problems? I made an upper support to help cure the problem. Mine used to be Nitro, but you can't run it anywhere public cause there loud so I decided if I'm gonna have fun with this I gotta go brushless. I added some Ofna foam trued tires. I also cut my own motor mount. Here is a couple pics of the project.
