I have a hpi nitro 3 it has a hpi .12 evoII, 2 speed, full cvds, heavy duty diffs,upgraded gears it is pretty damn fast and i think it is time for a new motor. I dont really go to the track that much i usually set up a track at a office buildiing to race but i usually just staight line race and i need a more powerful engine i was think about getting the novarossi ns12s3 or the ns12s5. Does anyone have any reviews on these engines and i will take any other recondemations. And does anyone have any exprience with one these engines in a hpi nitro 3??
Thanx
