Well I put my MX-5 body on my 90mm brushless chassis (3500Kv Rocket) and it's quick! Geared at 10/53 with the throttle at 96% on the radio I was able to run 40 lap practice stent with a fast lap of 3.751 seconds and avg. of 4.2 with 2 bad laps where I tipped the car on it's side rubbing an inside rail. Going to try times with -1mmW rears and see what the clock says.
Have Fun and Drive Fast! Drew
