Want to make a unique BL truggy. Need Ideas.

Baja is way too big for me. I need something that I can fit in my real car, not something my real car can fit in.

I like the 3 speed because it allows me to gear taller between the spur and pinion...plus its automatic which makes it sick. Basically I will get more top speed for less amps with a three speed. 1 and 2 speed trans are good for stop and go type driving, which is what the application calls for most of the time in RC, however I will be driving this RC "freeway style," going at a constant velocity most of the time with little brakes/reversing.
