I have 3 Kingtech's now and one Jetcat left, my Jetcat 120 threw a blade about 8 hours after it's first service and I tossed it in the trash. Luckily I was able to land my F-15 without damage. After doing a slow pass, I throttled up and it seized, I was low and slow and just went past me! A lot of credit goes to the F-15 design.
Anyway, I will continue to go through the trouble of sending my one Jetcat turbine to Germany for service. Jetcat Germany is aware of the problems with Jetcat USA, they said that no one else will take the business on so they are stuck with the current management. Great product, bad US service.
