Thank you for the link Rob, much apprreciated.
So what voltage are you planning to run Elliot? 3s, 4s lipo or 10cell NiMH? The final axle speed seems slow on my adt too, but with a big tire afix to it, it moves pretty quick.
You're moving right along with the build... I should build this way too, before painting parts to find the trouble spots, but I have this resolute about doing things twice ...and all too often it happens anyway.
