Hello guys,

Brett, happy you fixed it.

I have always used CP 30% Heli too, one of the best fuels for the YS ever, but Cosmo BlackPower had better transition, so fuel affects the transition for sure, used also Byron Gen II and worked very well, but better on PowerMater, since VP Fuels took over, I immediately felt the difference, did not like it, and had to sell lots of gallons. I will try Rapicon as I moved to Spain now, and if Christophe an Scott uses it should be good hehe.

I also have an Amethyst with a Hacker motor, so actually can fly both and experiment the difference, really if electric was that much better, I will be flying electric only, but cannot get away from YS, specially, at the end of the day, making a flight with no clouds and no wind.....uffffff, no electric comes close to the feeling..

One thing on the valves, a lot of people get the clearance too tight in hot enviroments, just make sure there is clearance so when the engine is hot, the valves do not leak as they are pushed open.
