Master Airscrew - K Series 13x5 Propeller

This is a Master Airscrew Injection-Molded Fiberglass-Filled Nylon Propeller.

            This is the "K" Series of props for 4-stroke engines.              

                Excellent for Any Type of Application, from                    

             Training and Sport Flying to Serious Competition.                 

FEATURES: NASA Airfoils and Constant-Pitch Designs enable this Propeller to    

            deliver more Thrust at Lower RPM.                                  

          The Latest in Engineering Technology used for this Updated Design.   

          Lower Noise and Accurate Balance                                     

          Available in a Wide Array of Sizes to Suit Every Application.        

          Propeller is totally fuel-proof.                                     

INCLUDES: One Black 13x8 WIDE-BLADED Fiberglass/Nylon Propeller                

SPECS:    Center Hole Diameter: 3/16" approx.                                  

          Propeller Diameter:   13"                                            

          Propeller Pitch:      8"                                             

REQUIRES: Depending on the engine crankshaft size, the propeller may need to   

            be reamed to a larger size using GPMQ5005 (SAE) or                 

            GPMQ5007 (Metric).                                                 

COMMENTS: Four-stroke engines are typically higher torque engines and should   

            use the larger props indicated in the range.                       

          Recommended prop ranges will vary depending on your particular engine

            and airplane.                                                      

          The Chart below represents average prop usage and should be used as  

            Only a General Guideline. Always refer to the manufacturer's       

            instructions included with your engine.
