Propeller Off 3 (February 2021)

The O-360 engine with a 72″ Hartzell prop is a fairly popular combination but try as I might, I could not find a suitable second hand item. MT Propeller in Germany manufacture a three blade composite prop with the required approval for the 207. It is reassuringly expensive and there would be a three month wait for delivery. I spoke with an owner who had recently fitted the MT prop to his 207, he was very satisfied with the results, particularly the smooth running. I was not so sure the benefits justified the £13,000 price, there must be an alternative and hopefully cheaper solution.
