I'm in love with the Morris Su-do-Khoi. I've been flying for 12+ years and have tried hovering with some success with my .40 sized Tsunami (hence my alias), and would like to step up to a plane that will do it easier and better. I've been looking at the engine options available and I don't think I want to use glow, I hate to think of how much these big engines will use.
Morris recommends the MVVS 2.15/35cc, and it looks like a neat package.

Does anyone use this engine? Can you recommend it, or another brand?

The BME 44 looks like a good choice too........
TIA
