For comparison: I had a modified Zenoah G26, lightened and running EI, on a Funtana X100. Engine with muffler, ignition, switch and battery, 46oz. Spun the Xoar, and Mezjlik 18x6 props at approx 9000rpm, and AUW of the plane, dry, was 10lbs even. It was just enough for 3D and really good Imac flying. Any little bit less power, or more weight would have put the end to good 3D performance. At 11-12 lbs you could add a macs pipe to this setup, and spin the same props at around 10,000rpm, and this would make up for the weight. Chad
