The discussion so far has been on fitting adjustable and inflight variable pitch props to Rotax engines. Has anybody fitted the Sensenich 2 blade ground adjustable prop or any other type of ground adjustable prop to a Jab 3300 engine or an inflight variable or constant speed prop to the same engine? If so what prop type and what were your experiences, the results and your thoughts on doing this? And what are the drawbacks and points to watch? We are keen to get experiences and opinions here as we are glider towing with a J230 and need to get the maximum out of a limited engine power. i believe that the Canadians and British Jabiru owners are throwing away the Jab props and installing the Italian GT props for better performance. We will also need to get any prop changes through Jabiru's system as it is a certified aircraft.
