Default Re: More Engine and Prop Tweaks

Hooray!!!

I put the old 21" pitch x 14 and 7/8" diameter props back on with the engines up two bolts.

Here are some numbers:

Cruise @ 3,500 RPM's = approx 33 miles per hours (getting about 1.8 miles per gallon)

WOT @ 5,400 RPM's = 55 miles per hour

Big difference. Everything (overall ride, WOT speed & gas performance) has improved. I have a feeling that the best long term setup would be to move the engine down one slot, but I am going to leave it as is for now.
