It would be a shame to run a cowl at all with this engine line. Very nice work I hope we get to see a lot of them. THe 100cc might fit the bill for my tastes. Cool goes a very very long way for me. Airworld will be introducing more 4 strokes soon too. Good time to wait and see. I don't mind tuning some valves once in a while to get that sound and torque.

Dick, did your review of the H9 Sukhoi 33% use a G62? I got a used suk hanging that needs and interesting engine!~)
