If your using the e-maxx transmission it's easy to mount using the rcmonster heatsink, but if you've got a slipperential it could be a bit harder.
With my 7xl on 14 cells and a 13t pinion, a 3" fan couldn't stop the quark from thermalling at racing. It seems to like the neu a bit better though, but I haven't gotten to race it yet on 5s.
I'd didn't get to got to racing last night, because it had been raining a lot at the track, and I don't know when I'll be able to go again, because I think that was going to be the last race before they stop for 2 months or so over winter. Yes things are backwards down here.
