Fencer,
The power to weight ratio will be a problem. You still have to use 20% oil, if you don't covert to a needle bearing rod. It will have the power of a good .40 glow engine. The ignition and battery will weigh almost half a pound. The BME 90 should run like a good glow .60 and weigh as much as a glow 1.20. You can do it, but what is the point?
