Try this prop. APC 6 x 5.5 cut the length down to 5.5 to 5.3.

5.5 is the sweet spot. Match the stock tip design to your cut down prop. BALANCE it !!! You may want to purchase 3-4 to get it right.

run on 4 cell. Post your thoughts.
I'll post a motocalc spread sheet when I get home.

If your running the APC prop, and the size/numbers are and should be facing the nose of the plane,you have no need for a pusher prop.
