This is an older thread, but guess I should report that I have acquired a hpi micro rs4 and a 1/16 Kyle busch vxl. All I'm waiting for is a Lipo for the traxxas and ill find out how good or bad it is. If bad then I may rip out the electronics and put a big block conversion in the mrs4.

I need mrs4 parts!!! Anything and everything considered!!

Thanks to all of you for your responses!!!
