We will see. As soon as the weather behaves and gives me a chance to finish break in the Moki I'll be able to tell if it will like the 20x6-10 vs the 18x10. My intent is 3D with this airplane and if I can get the 20" prop to swing well it should be a better match for 3D than the 18.

BTW, so far my break in process points at some very respectable numbers for the 18x10 Zinger Pro. I currently have it adjusted for 5+ turns out and have to adjust the throttle to keep it below 7,000 rpm. I'm sure the Cline Regulator has something to do with this -- there is no doubt in my mind that when it comes to the time to lean her out she is goiing to top 9000 with the 18x10 prop.

I don't know the numbers but I'm hoping for between 8000 - 8500 with the 20x6-10 prop. What does that mean in thrust for this 14lb bird?
