Well it took 4 months and a lot on modifying the body, but it was worth it. My Balsa USA Stingray 120 with a Ryobi 31cc weedwacker engine conversions flies great I am getting 7200 RPM with a MAS 18x8 prop and that is giving me enough power to do all the Basic maneuvers. I am just past the learning stage so this is just fine for me. I had a great time building both the plan and doing the engine conversion.

Thanks

Nice looking bird!
