For a minute there, I couldn't figure out what on earth you were talking about...

Are you talking about the GWS Zero? Heavens no! That Fox .30 weighs more than a GWS Zero should fully outfitted and ready to fly. It'll be uncontrollable at best, but will probably tear the plane, and maybe you, to pieces within seconds.

I'm trying to think of a good glow engine forum for your question. When I do, I'll move it and let you know.

BTW, JK Aerotech makes some inexpensive foamie planes designed for .25-.30 glow engines, though you may want to start out a little less ambitious and go with a Sig LT-25 for your first glow plane.
