I was looking for an upgrade from my TRX 2.5 for my REVO. does anyone know what a good engine would be? i am looking for an engine that is in range from .21 to a .26. thanks a bunch.

Picco.23@300. plus bucks, RED

Met someone at the track who had just dropped in an OS .18 in his revo. This truck was screaming and he was only running about 190 degrees w/ the stock cooling head. It was impressive performance at a very safe temp.

I would say that if he was running that good at 190 can you imagine how much better it would run if it were properly tuned , the engine must have been running very rich at that temp. RED
