Well, a VERY smart guy once told me flat out:
"You do NOT want to be the first kid on your block with a new turbine."
Keep that in mind. Even the best manufacturers out there have teething troubles sometimes with new products, so unless you are willing to deal with that potential, wait till the first batch gets out there and flown a bunch. Just food for thought.
Me, I'm waiting to see, but it's a pretty exciting engine, looks great to me. British-made, too, which is a plus for me.
