I don't agree with the mindset of using an electric motor to synthesize a glow motor. It'll never work as well as if you use the most efficient setup you can physically fit in the aircraft.

I see this all the time, and I used to go along with it, "hey there sonny, what you got in that thar plane?"
A something something something"
"What's that equivalent to?"
I used to tell them a glow capacity, but I soon realised that a) it's misleading and b) annoying. Now I reply in watts.

Some get it, some look at me like I'm retarded. That could be because I drool a lot and stare at them crazy-eyed.
