why are my temps so high???

Sounds like my kind of r/c...

Anyway, I have 1 neu motor ATM, a 1515 1.5d that i run on 4s in a erevo. Motor rpm is around 40k maxx. With 19/50 gearing and some taped badlands it is good for around 45mph. I think that is the best that motor will do without going over 160f. I personally think that naything heavier than that revo would require a larger motor, like a 1521...

I am also building an aftershock (lst like truck) that i plan to run 6s on. I have a hacker 11xl, but it will only spin 33k rpm on 6s. I will see how it does, but have a feeling that a 1521 1.5d (1900kv) would be a great motor to move the heavy truck around. It would spin over 40k, near 42k maxx. Or I could go with a 1521 1y (1577kv) but that would only get to around 35k max...

well, everyone is right. The cc rep is right, you can run the neus at 50k rpm all day- with a proper load. And everyone here at RCM is right. Less battery or less gear will drop your temps. But mostly, listen to Linc. Dropping the gearing will lighten the load and allow you to keep your high winding setup. It's "cool" to gear for 60mph but pretty impractical. You need a BIG space to go that fast and it's out of site in a second. Gearing for 45ish is plenty for me and I play real hard. Also playing with the punch control on the MMM can tame your wheelies down.

thanks to everyone for all the replies! I dropped down to the 12T on dirt yesterday, and for the 10 min that I ran, temps were NICE! I don't think there's any way that I can fit that big spur in there lincpimp, so if the 12T pinion doesn't keep me where I need/want to be, I will have to switch motors.
