RE: The Weirdest use of Glow Engines. is this for real?
A drone would make more sense than something to do with flaps. But, 20cc to fly a drone? With $20 "toy" engines (1970's)? For the effort they put into this, they could have machined their own engine. I agree running on glow could have some advantages with receiving a clearer signal from a drone, and four engines may keep vibration down. They did have small chainsaw type engines back then which would be easier to modify, and could be run on glow.
