RE: Electric to Glow conversion. Yes, E -> G.
I would concur with Greg,.. you're going to lose performance, not gain it, by going glow on a smaller plane ,.. actually anything up to about 140~160 size i get FAR HIGHER performance electric than glow,.. but it does cost more(a lot more on the large stuff). When going really small, say 40 glow size or smaller, the performance difference is even higher. One good example is the Banchee. the "Banchee-G3D" (glow version) turns out a pound or more higher in weight than the Banchee-E3D (electric version), and of course the 46 glow has quite a bit less performance than a 500~600 watt electric setup spinning a 15 to 18 inch prop.
