Well, having built BVM and AD kits, I for one will emphatically say I would have ZERO issue buying one of these jets. Eric's designs consistently fly amazingly, and I can't remember hearing any problems with AD kits. The price is awesome for what you get, and they build very easily.
Many people have said "sure they're cheaper, but they are more building than BVM" I don't agree with that either. My Exocet was faster to build than my Composite Super Bandit. And the Exocet is sheeted foam wings. I've had many issues with the build on my Super Bandit which I won't get into since I'm not wearing a flame retardant suit, but despite those issues, I know they're a great plane. However, bang for the buck, AD takes the prize. I've already spoken with Helijet and asked Dean to be sure and hold an Angel for me as soon as they're available, not that I'm against the kingcat or bobcat, but personally I think the AD designs look a heck of a lot better, and at the price that's been mentioned, they're half the money, I like that!
So anyway, from somebody who's built and flown airplanes from both manufactures, I can say that I would never have any concerns buying a new airplane from Aviation Design
