The 600xl has a lot of power on 6s in a Losi 8t. It also has a lot of acceleration on 4s in a Hyper ST, but lacked some top end. Running it on 8s in a rustler sounds like a lot of power. How fast are you trying to get it to go?
Well that's up for grabs. What's more important to me is acceleration. I want it to be gone before I hit the throttle. Insane speed is just a side effect of insane acceleration. One of these days I'll find somewhere to race it. Probably the airport runway - we'll be seeing who can take off first.
