i have had one of the first p180rx to hit usa..i have about 4 hours or so on mine..not a failed start or hickup.. fast throttle response and no flameouts.. i was talking to bob wilcox and he was telling me the concerns were on the 100 rx and 180rx not the 140s...he advised me to send it in so why risk anything bad..i boxed it ...i am a jetcat guy through and through. i have no problems sending in for service...its and engine..these things happen...
