Thanks for the response back. That does help a lot. I ended up putting the 46 glow in it, and it fly's great. Now I need to find a plane that isn't tore up to put the PJS 500 3D in. I bought the foamie with the engine, battery and esc for 20 bucks, so I'm not complaining, killed the foamie, but don't want to wast the engine.
