Well, here is my CRT.5e

[brainanator]

What I have been able to drive of it I think it works great on 2S.
Temps were around 130-140F on the motor, and cool on the ESC after some runs on the track. Like I said, I haven't been able to test it as much as I wanted to since I've broken the knuckles so quickly...and now that I'm back home it had to snow again...haha.
Speed seemed right where it needed to be for the truck. I have a heat sink I'll fit on the motor if it does decide to run hot when I can finally open it up for a whole pack!
