I've been tuning and testing this and have it where it handles well on dry grass on 8s geared for 50mph. It's still twitchy at high speeds if I punch the throttle (lots of power!) - but it's very controllable. I'll continue to tweak it but I'm happy.

Temps after driving it pretty hard for about 20mins (90F ambient):

batts: 114F
esc: 132F
motor: 160F

I also checked my diffs' temps and was surprised to see my center diff was 190F (rear - 145F, front - 130F). I have 25k diff oil in there now - I may have to thicken it up again if the CD temps are a problem.

Anyone know how high is too high for silicone diff oil - or diffs in general? I expect the silicone can go much higher than that - it's used for cooking utensils rated for 400F. I've never paid much attention to diff temps before, so I haven't given it much thought.

Edit: I'll get vids up later this week or weekend when my wife gets home with the kids and the video camera!
