DonH21 I'm currently using a 12x4 APC prop with 10% Cool Power. The engine will get to 12,600 rpm maybe higher (13,000 with a 11x6 APC). The engine could use a quicker response. They say this engine is also heavy but I don't know the weight. The engine always runs wire to wire and has about 50 or more flights on it. The other Rossi 45 RE in our club on the same plane had a problem with the o-ring between the muffler and exhaust port. I think it happened because he never secured the muffler and the vibration beat it to pieces. He ran into problems getting a replacement and gave up on the plane/engine. I have heard of replacing the carb with a Perry for better response. Also, the Rossi RE/tuned silencer is very noisey and some one just commented last week end that I should get a real muffler for that engine. Ouch!!!!!!!!!!!!
