Master Airscrew - 3-Blade 11x7 Pusher

 This is the Master Airscrew 11x7 3-Blade Pusher Propeller.           
                                                                               
FEATURES: Constructed of glass filled nylon for strength and durability        
          NACA airfoil                                                         
          Scale look and true pitch                                            
          Accurately balanced to create a greater thrust at lower RPM          
                                                                               
SPECS:    Diameter: 11" (28cm)                                                 
          Pitch:     7" (18cm)                                                 
                                                                               
COMMENTS: The general rule for converting a 2 blade prop to a 3 blade is to    
            subtract 1" from Diameter OR subtract 1 from Pitch.                
          Pusher propellers are designed for airplanes that have the engine    
            facing backwards in the rear of the plane, PUSHING the airplane    
            forward.                                                           
                                                                               
          PER MASTER AIRSCREW: All 3- and 4-blade props are balanced           
            dynamically at the factory prior to drilling. The mounting holes   
            are then drilled slightly off center, if required, to properly     
            balance the propeller. As such, the mounting hole may be slightly  
            off center. Master Airscrew assures us this is perfectly normal    
            and will not cause problems during use.
