Thanks for the replies.

I hear what you are saying about the gear pitch and fit. This is where a SOLID motor and tranny mount is imperative. Any flexing or twisting will change the mesh and will strip anything. Still, I think I'll stick with the Mod1 spur, if only because they are easy to get at my LHS since they are stock Traxxas parts.

My stumbling block is the part you have nailed down: the motor mount. If that was available seperately, adjustable vertically, adjustable horizontally (to bring the pinion laterally closer to the tranny), and in 3mm-4mm thick aluminum, I'd definitely get one if the price was reasonable. Basically; a univeral mount that will mate the motor pinion with the stock spur -or- your milled spacer/non-standard spur combo.

"My design" as you put it isn't even off the ground yet. I was waiting for parts for finish a current Revo design and I had an extra chassis, so I started messing around with a design that uses more stock parts (easier availablilty locally). I have plans for it, but I ad kinda halted until I could get a motor mount designed. Making things with Lowe's aluminum stock on a vise is difficult to do accurately. :)
