I was just wodering how a "turbine engine" had 150 hours before overhaul..........let's see............lets say 15 minutes per flight, so 4 flights per hour, times 150 hours, equals 600 flights.....I'd be hard pressed to find alot of flyers who have had 600 flights total. Are you sure on the hours estimate, if so man you got a great engine. My RAM 750F has to go into the shop after 200 cycles......hmmmnnn, just wondering.
