Got a fellow club member that is all glow and bought the evolution 10cc for a tiger. While the engine is smooth running and easy starting engine. It is also just as messy as glow because of the 20-1 oil required. I would love to know why the OS 40cc can be ran at 40-1 and saito and evolution have such high oil requirements. All that being said I still think it is a good value for what it is. He can't go wrong with the engine for that plane.
Shouldn't be AS messy... Most glow engines run over 3x the oil of the Evolution 10cc (5% vs. 18%). 6.4 ounces per gallon isn't too bad for a small gasser in my opinion.
