If you look at the costs, I doubt someone want him to build a kit for them.

It probably means 4-5 ARFs in week, but if he so busy, he would not need to 'indroduce' his business here.
Probably not a scam, but not very useful for most of us either.

No matter how many Arfs you assemble, it does not make you a professional builder.
I'd expect to see some scratch build planes and people with a big smile next to them on a picture.

Usually the shipping costs are the deal breaker in sending assembled planes across the country. I wonder how that would work out.

We all love to build and fly our planes, and we spend a lot of money on our hobby, probably more then we should
So I can not see having someone build my plane, I'd rather spend the extra cash on a nice engine or the next plane...

As long as he does not offer something new and extraordinary, I don't see the point of dealing with this.
