The OS 50 will fly the plane but I'm not sure what performance you are expecting. If you have been reading the various comments on 3D airplanes for performance they tend to be powered higher than recommended. For example if your looking to go unlimited vertical then I'd recommed a larger engine. However if you are a biginner or Sunday flyer then your OS 50 will do fine. I really think the .46 UCD with a consertative engine is a good trainer, yet safely capable of doing a lot more as the skill level improves. If you have more power you don't have to use it and fly half throttle. Three things I like in an airplane, plenty of gas, altitude and power. I call it insurance.
