Thanks for that link, on the Allison 250 series, really interesting. I hope these guys keep going with the composite concept, I think they will benefit from this experience(given some time) They have; shown it autos beautifully; it doesn't kill you in a water landing (try that with a robi ) ; it stayed pretty much in tact, so great strength in the airframe. Its a shame they can't put together blades, mrgb,trgb, all from other known main stream manufacturers so as to cut down the certification times. Seems counterproductive for any new type to have to prove every bit of there new aircraft. My wish would be for say MD500 4 blade hub, new burp blades for the 500 series, trgb of anything that's big enough and been around for awhile. Put in the new RR300 engine and lets go flying. Of course, that's a daydream
