Product Description

Fit a Master Airscrew

  • 7*3, 7*4, 7*5, 7*6, 7*7
  • 8*4, 8*5, 8*6 

propeller to a 3.18mm (1/8in) shaft.



  • 2 in pack.
  • This prop adapter is 3D printed and has a finish which is different from that which would be achieved by injection moulding.
  • The ridged surfaces allow the adapter to be
    • fitted to a propeller more easily,
    • achieve a more flexible fit if the propeller is not exactly the same size,
    • and grip both the propeller and the engine shaft quite well.
  • However as they are not molded each one is slightly different and may need to be tidied up a little before use.
  • If necessary, use a blunt hobby knife to gently scrape away any particularly rough spots so that the finish feels consistant to the touch all the way around. When fitting, it should snap into place with pressure from the thumb but may be tapped gently if necessary. Trim to length as required.
  • Each adapter is fitted with a tag for easy identification. The fingers on the tag when read from right to left indicate the values 1,2,4,8,16, in that order. Add the value of each finger to get the type number.
  • To remove, place a pen in the hole and while holding the prop push the adapter out from the front.
  • May also be suitable for use with other similar size propellers.

 Note : By using these adapters the user agrees to take responsibility for their safe and appropriate fitment and use.
