The OS 90FX you have should be plenty of engine for your plane OverTheEdge . No need to over do it. As for your question xcarlos, I didn't have a tach when I test ran the engine so I don't know what the rpm's where. I have a tach now so when I install the engine back on the plane and get everything finished I'll check the rpm's.
