Hay Big Greg,
I've always had great success with the Neu's keeping things nice and cool, great choice for your Revo.. For what it worth you can do the trans mod to the 3905 slipper relatively easy. I did a thread a few weeks back on the step-by-step procedure

Thanks for your time and great looking Truck bye the way..
Have a great week.. (thank god it’s a short one)
Shaun.
