Hi Guys,

I am new to YS engines and would like to find a book of some sort that describes how they operate, particularily how the fuel and pressure systems work. It's not obvious to me from the exploded engine drawing in the owner's phamplet. I am particularily interested in the YS 110 at this time.

Thanks,

Bluesky

Hopefully these will help you out some:

Thanks Gulliver,

The tech.flygsw.org/ys110 site was exactly what I was looking for.

I appreciate the information.

there is also a wealth of info on the YS engine forum here on rc universe. I am running a 1.10 in my showtime 4D and it is sweet. OS type F glowplug, Cool Power high performance Heli fuel (it's orange and has 30% nitro and 22% oil) It is the good stuff for this engine. I am running an apc 16.5x5w on my plane and it works for 3D or pattern flying. The motor is very easy to run, and the NEW improved 1.10 with the external regulator is rumored to be even easier to operate. Don't fear the YS 4 strokes, they are so easy to run. [8D] VT
