| Pete,
You should have plenty of power there, even with the standard muffler. Mine flies like a home sick angel. Look for any blockages in the fuel line, or any drawing of air. The standard muffler will restrict the engine, but even so mine easily copes with a lot of 3D work. Could be the engine just isn't run in yet. I'm running mine on 16% and have yet to run out of power. The OS50 is probably the most powerful 50 engine there is about... something must be a miss somewhere on your model.
Cheers
