YS(YZ) 110 Rocks
 

Ok I know that there are pro's and con's with YS engines and this is my first YS. But let me say it has run GREAT right out of the box!!! I've owned a varity of engines, but this YS is a power house. I read everything on RCU about YS engines and most like them. Well count me in.

I have it on a CG Extra and it is not my CG Extra (don't ask, something about trees). With this engine that isn't even broken in, it has unlimited vertical.

I know they suck expensive nitro fuel, but who cares!!
