ORIGINAL: Tauri Flyer
Possibly 2 Echo/Kioritz ,,,hmmmm they were either 16 or 18cc engines. Conversionists sometimes discard these because of the power to weight issues,,but they just might be the ticket for your plane. Converted to EI they should be light enough and I see that plane only calls for 2 .91 4 strokers.
91 4-strokers would struggle get this plane off the ground up here in Colorado. If I were to use glow--I'd have to put 1.20 4-stroke engines on it. It might be just a tiny bit too much power--but I'd rather fly it at 1/2 throttle than worry about getting it off the runway everytime I attempt to fly it.
Thats why I think an 18--21cc gas engine would be just about right.
