Sweet jesus... I've got 3s lipo and a mamba compX in my Xray M18 and I have yet to get it to top speed and still be able to control it.... I've had it up to about 50mph at half throttle... Litterally driving it down a road chasing it with a real car :D

You sir, are nuts!

Anyways, I don't know of any SMALL controlers that would work fine... Check out the store I think the MGM ones were kind of small??
