Ed: yes, I saw the post about the Syssa engine. Interesting - but it does need development. Gas engines tend to run quite hot (read about the SAITO FG-36 : The engine runs considerably hotter than Glo). The nitro in the YS helps significantly with cooling. Gas is good, but it's meant for bigger planes I guess!

Well, this engine appears to have raised the bar a bit closer to the YS for a 2 stroke..... and gas at that.
It turned the 18.1x10 apc on my overweight and oversized pattern test bed adequately on the ground with excellent performance in the air. I am very encouraged and looking forward to more experiments with different props.
The sound quality is the same or better than most 2 stroke set-ups I've used and /or witnessed.
I agree that pretty much all other gas set-ups are not desired in pattern for all the commonly expressed reasons. This new engine is a show changer in my opinion. About the only thing we want to overcome is the gasoline smell. Need to find a reliable source that will supply us 100LL Avgas
