I just went through this & bought the Kingtech K180G. When I bought my P-100, I loved it but wished I had spent the extra & went with a P-140RX. Now that I was in the market for a new turbine I decided to go with a 180 size so I can power bigger birds also. My buddy cashed & twin P140RX 20K aircraft TWICE due to P140 flame outs, so I decided to give JetCat a break. Also a 180 tuned down in theory will last forever.
