I wasn't aware of RCProductDesigns. Thanks, I'll check them out. I was going to simply order a motor mount, but for $40-$60 (versus .25 cents) I decided I'd drill and tap one out myself. Actually, I did break a $3.50 tap and had to use a second piece of aluminum so the total motor mount cost went up to $4.00. Darn it! Actually, I will have to re-machine the bolt holes for the motor when I add a larger pinion. I need to allow for the motor to be moved away from the center diff as I try different pinion sizes.
Let's keep this poject going and everyone informed. It's a lot of fun and I'm sure it will be plenty worth it in the end.

I emailed Dan at RC Product Designs, hopefully he'll keep an eye out on this post and share some lessons learned from time to time.
For us do-it-yourselfers, buying the Traxxas E-Maxx motor mount for about $6 gives a good cheap pattern for copying the geometry for making new motor mounts (or just use half of it). It seems an inexpensive time and trouble saver for taking measurements and making prototype parts. We thought about a dual Velineon set up for awhile and were going to use the motor mount, but decided to keep it simple and stick with one motor (we think dual brushless on the same spur might be a feedback and motor control problem).
You're very welcome for the thread, we plan on racing competitively this coming summer and as we take pics and get some testing results I hope to keep this thread updated. Hopefully others will also add their projects like you did - we can all learn together.
