Homebuilts have entered some weird twilight zone between
true experimental and factory-built aircraft. A good example
of this is

That sure looks like a certified aircraft manufacturer, doesn't it?
Not sure why people expect solid engineering from a homebuilt
kit maker. Not to pick on Murphy, but I remember the guys at the
airport hanging O-320's on the front of their Rebels and the firewall
collapsing at the top, so they stuck a bracer bar between the
engine mounts at the top of the firewall. And they were sticking
doublers in the tail. That's ok, but remember, when you make
something strong, you're merely transferring the load elsewhere.
Oh yeah, Murphy Rebels. I remember they had the weirdest stall
behaviour. I'm no aerodynamic engineer, but I wrote an article
about it, identifying the problem and one fix. People still email
me about it, many years later. That's what homebuilts are like.
The point is that homebuilts are CAVEAT EMPTOR. People liked
to pull the wings off RV's, I remember. Andy Philips fluttered his
rudder. Looked like someone put a stick of dynamite inside it.
That's what life (and death) is like with homebuilts. Certified
aircraft, they are most certainly NOT. Ask Steve Wittman, who
knew more about homebuilts than almost anyone. And no, he
wasn't killed by the B-52, ok?
