The propeller selection and installation
Make sure the prop, spinner and prop bolts before each
flight! Loose prop bolts allow prop movement which will

Selection:
• The following props are recommended: 22*10, 23*10, 23*8.

Installation:
• You must use a drill press to drill your propeller from the rear.
