HI Dave,

Great job with the Supreme! MY OS 140 RX on 20% Nitro turns the Mejzlick 18x12 8100 rpms. The D.L. APC 15.75 3B repitched to 10, turns more than 8200. It is a great motor, just get the S.S. rear bearing for it when needed. Without a doubt, this has been the most consistent engine I've owned. Engine maintenane consists of running the engine out, drop in a little oil, crack a beer, enjoy salsa and chips. Very clean too. The Webra 160 is a plane killer.
