Propeller for Rotax 447


Recommended Posts

 I've recently acquired a rotax 447 paratrike, but it is the original Romain 2 blade heavy (and very noisy) 2 blade prop. I would like to replace it with something quieter as I really don't want to annoy those on the ground. Does anyone have anything suitable for sale, or even able to suggest appropriate diameter and pitch requirements for that engine?

Jock has said that he had an Arplast 3 blade at around 125 - 130 diameter on one of his earlier machines so I may need to look for something like that.

Any ideas gratefully received☺️.
