One of the components that can make a big difference to the performance of the aircraft is the propeller. I have researched & considered 4 different types. The Airmaster looks to be the best fit for my needs as it is supplied as a complete matched kit, is an easy install, is use maintained every 100 hours and has a 2000 hour TBO. Coupled with claimed good performance I decided to order it on the 20th February 2019 with delivery due mid April.

Due to a problem with their CNC machine I finally received the prop at the end of May.
