RE: os 1.60fx o.k for this application?
In an easy day you may squeeze 5 flight on 1/2 a gallon, but that is max !!
I do run it a little rich, but on an enclose cowling FX 1.60 does not like it and heats up fast!
I may put it in my CG Pitts monster since I burned out my YS120 with the wrong fuel, both can handle the scimmitar 17x8 well.
enjoy.
ps: I run it with 10% nitro and 18% oil, there is not such a thing as, "Too much oil" in Baja`s sandy/dirty soil!!
