Thanks for the compliment.
I made the motor mount, it is just a piece of aluminum screwed to the center diff mount. I don't have any plans for it and don't plan on making any to sell. In fact I may get one from RC-Monster Mike as his work is real nice, and he does custom stuff as well.
The battery tray is a kyosho part, RC-Monster sells them (they may not be in the store, email Mike if you want one).
Motor; the XL feigaos are popular, but I am starting to think they run a bit too hot for my liking. Alot of guys on here are going with the Neu motors,as they are much more efficient. 1700 to 2000 kv seem to be the most popular
Pinions I have been getting here at RC-Monster. Gear for the speed you want (use
BrianG's calculator), most are gearing for 35 to 40 mph for racing.
Spur gear is also a Kyosho part available here at the RC-Monster store, it is plastic and allows the use of non hardened (cheaper) pinions. Some have used the stock spur gears, but a hardened pinion would be required for that.
BEC is a Dimension Engineering ParkBEC. It was smallest lightest one I could find, but if running high torque digital servo, I don't know if it will be enough. I have no prob with my old Hitec605MG in there.
The biggest thing you have to do is get rid of the nitrocrap. The servo plate will need to be cut so you just have the steering servo mount and no throttle servo. And of course bolting on you motor mount and battery tray.
And yes, screw nitro, in fact I have never run nitro in 20 years in rc.

thanks for the tip, I had considered that as well, just trying to find one on ebay cheap so I don't haved to pay full price (those things are spendy).
