The pro-pattern 20 is an excellent fuel in the YS engines. This is Cool Powers blend for 20/20. You can also run the CP 30% heli...

The 14-10 is a good prop to start with....You want the engine to turn int he mid 9000 range like 9400-9700rpm SO pick a prop and fuel gives you this for the High end rpms.


The HS starting point should be about 2 turns open...Should lean down to about 1.5turns...The regulator should be flush with the case,a dn the low speed air bleed screw should be about 1.5 turns open from full closed....

Go here for some basic instructions on how to run it....
