I really like the idea. I have a couple OS FS .20's which I would like to put on a light twin, as well as a few .10-.15 size engines. I actually tried to instal a .15 on one of those beginner pusher type planes (firefly?) but never got it to fly right (I had a coroplast wing which was heavy and really sucked).[X(]
I have oftened wondered if there was a problem with glow fuel and the foam parts used on many park fliers.

Another similar question. Why are some props sold as electric only? Many of these electric engines spin at the same or faster speeds. Is it a liability problem?
