I sent in a brand new P70 in for repair that would just make a loud racing bearing noise. So they replaced the bearings and I got it back a month later. When I got it back it would not want to start on propane so I send it back, and that took another month. I get it back and install it in a jet and al it would do is spit and sputter on the runway, now I am just aggravated with the whole service. So I send it in and it took them another month to get it right. I call up and ask, why are they so slow in getting my turbine repaired for the third time he stated that they only have one person in the shop that worked on the engines and Bob was working on filming a movie and that was priority, so that was the last time I sent my turbine or would ever buy another Jetcat as long as I am in this hobby.
