Hey Fred, thanks for the info.

I don't have a tach yet so I have no idea how fast the 61FX is spinning the prop. When I was braking in the engine I had a 13x6 on there. I never flew it with that prop but the ngine wound up higher after I put the 13x4, or at least it sounded like it. You think I should go back to a slightly higher pitch? or maybe that awkward-sized prop that is something like 12.75x3.75.
