Default RE: What Engine do i have?

OS FP. Nice reliable engines.

They came in lapped steel and ABC flavors. You will want to use a fuel with a high percentage of castor oil to keep it alive. It doesn't need a lot of nitro. I have several FP .35's and they run fine with cheap 0% nitro 80/20 FAI fuel.
