Has anyone felt the need to even run 6s on this thing yet? I purchased another one (roller) from a forum member and installed the newest Castle /1515-2200kV sensored motor combo in it.

Whoa.

Crazy insane fast on 4s. I didn't GPS it yet, but it feels close to 50mph with a 18t pinion. The only time you can bottom the trigger is when it's close to max speed without the front end coming up.

The truck continues to impress. I've never purchased "doubles" of an RC...until now.
