That looks like a very simple conversion to do, and you pulled it off rather well. All i will say though is keep an eye on the 48p gears (may need to go to 32p, may not), and tidy up that motor plate! looks like you just cut it & mounted it to test it worked, rather than worrying about neatness (if it looks 'factory' , then more people will want their own conversion).
Ignore the dumb questions some people ask on the Traxxas forums- they say why, I say why not?.....
