I run my 1515 1Y on 5s geared 16/38 and the motor has never been warm enough to worry about needing a heat sink.
What do you run it in? I run mine on 5s with the REvo spur on the slipperential geat mod 1 with a 16t pinion. gets warm, but nothing to worry about as well. and that is on a 95*F day.

I'm running it in a 3.3 revo with the stock tranny locked in 2nd.
