I converted a 1/8 buggy to on road....most nitro 1/8 to electric conversions are pretty easy. 1/8 buggys/truggys are about the strongest as far as durability goes. The diff fluids you spoke of can be adjusted to keep ballooning down.

If you want a true speed demon, the 1/8 on road cars such as the Mugen mrx-4R are land missiles and can handle like they are on rails. However, they are much more work to convert to electric
