RE: Best 36" wing
The prop range is about 5x5 to 6x4. 5x5 will produce more speed but the 6x4 will have more vertical.
I use the black carbon fiber 5x5 props and APC 6 x4 thin electric. I have ordered an E Zipper from hobby people!
The Mega 16/15/4 with 6x4 prop is what I currently use in my 48" Overlord. The Mega is a terrific motor for wings!
