140 FZ Prop Size

[John Ferrell]

I have found the 15-12 best for clean airplanes like the Prophecy while the 
16-10 makes a really big difference in the wider Focus. More Nitro means 
more prop & more maintenance. I like to see about 8200 rpm on the ground 
with a 140FZ and will prop down to get it. I run 15% or 20% Red Max all Syn 
fuel.
Be aware that extra rev's will make a little more noise.
