Now it gets interesting.
So compare post #1 and post #42 - which is quite the opposite. So what are the skills here?

Gray Beard - you can charge someone at your field $125 to assemble and set up their trainer plane. Fair price, but that works only locally, most trainers have a one piece wing and it would cost a fortune to ship it. And he does not test fly the plane or run the engine.
Well, I bought a used trainer and saved a lot of money.

Anyways now we went from a 'professional builder' to someone who just 'build' a few kits. Not impressed and I am far from being a GOD.
