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. :)

No reason we can't join forces, I am not proud dude!

The motor mount is available separately now, with or without the milled spacer. Mount is 25 plus shipping, spacer is 8 bucks plus shipping. Making it adjustable horizontally may take some redesign, let me chew on it for a few days, maybe the answer will come. 2nd gear lock hub is 20 plus shipping. Obviously you only pay one shipping charge if you order more than one part.

Just so you guys understand, I am not making a fortune on these nor do I expect to, that pricing barely covers the tooling and material, basically I am making about 5 bucks an hour doing these parts (less than most fast food employees). In other words I am doing it for fun since I can piggy back it on my other business (don't tell the IRS I wrote off all the CNC stuff this year).

The current mount is milled from quarter inch (6.35mm) aluminum stock drilled tapped and countersunk, and has a natural finish. It uses M3 screws (3mm metric socket head) and is very stiff.

The spacer/mount is made to work with the stock slipper.

Again I am available by phone to chat if you have any questions.

Also if anyone wants custom CNC stuff done, I am willing to do prototyping VERY cheap if you are any good with CAD...
