brushless 1/10th truggy (help and opinions?)

[tashpop]

did you get any further on this project rooter? mine seems a bit undergeared using 4cell a123's. i used a 12t pinion and from a stand still it hops all 4's about 4-5 times and is at full speed in what seems about 3 seconds. i'm over 30mph i think, but its my slowest rc top speed wise right now. i'm sure the racers would love my gearing, scary responsive and quick.
