I think you should put a little time into "blending" your bottom motor mount. It looks as though it could easily be an impact spot as low as it sits. I'd hate to see you bend it up. I wonder if there is a way for you to attach the stock Revo tranny guard to it?

I didn't get the chance to page back to the beginning of the thread, but did you cut out the motor opening at all? If not, you may be able to do this, and raise the motor just a few mm's (or not!).
Otherwise, great job!
