Hi Angus
Yea maybe, I think it was intended for the sport market But, I was surprised it performed very well with no breaking in on 20% Nitro.
It`s pretty cool here 60 deg, but the humidity was up in the 80`s. and I believe a good low cost high performance motor for the Pattern market. As far as the smoke trail with high oil content, I think it`s not a big deal really, and the sport guys like to see it as part of the tuning process.
While on the smoke trail subject, Chip has been working with Cool Power on a new low smoke fuel. Fred sent some for me to test, I have been running it. So far I like it, no needle change between the Heli ,low smoke , and limited smoke(chips fuel).my name
Power is the same. The only variable is performance in the heat. I have limited testing on that so far,But I like it.
With my new Cooling valve cover for the YS, it should not be a problem.
