My JetPROP is an outstanding aircraft and performer. During march 2004, I had my 1998 Mirage converted to a JetPROP using the Pratt & Whitney PT6A-35 engine. I converted what was a good aircraft into what then became an exceptionally good aircraft. Overall performance was significantly improved, even better than promised. Operating from the Northeast, this JetPROP conversion now allows us the use of shorter runways and mountainous areas which we could not safely use before. Other than normal maintenance, it has been virtually trouble free. I know of no other aircraft that can match the overall performance and dependability, including the cost to own and operate. The JetPROP conversion for me, was not a purchase, but rather an investment. It is a pleasure to fly, and I am quite proud to own it.
