Very good guys!

With Geokeli and Novaflier, we will have 2 differents set up. Let us know what you get with the 23x8 prop. I am sure it is going to work very nive on that engine.

In the meantime, we all know that Thrust H.P is not accurate but if we look at the Thrust and speed changes with 22x10 to 23x8, here is what we could have:

Menz 22x10, 7200 RPM, 68mph and 35.5lbs of thrust
Menz 23x8, 7000RPM (estimate), 53mph and 40lbs of thrust

It means a 23x8 prop at 7000RPM would give 'roughly', 12% more thrust for 22% less speed.
