I had Matt/Dustin build a Pponk for me from a 520 D probly about 4 years ago. Engine has been trouble free, I have around 550 hrs on it now. I would not figure them for the R and R, but I did get aquainted with a guy in the area, Kevin Anderson that I would highly recommend for that part of it. Kevin would also be great for any other Cessna maintenance type issues. PM me for any further inquiries into this subject.
