Ira,
I didnt go thru the entire thread on that other board, but the lawyer opinion letter is just that, a lawyers opinion. Some lawyers have some crazy opinions, resulting in suits for millions of dollars for spilled coffe. I would love to see the FAA response to his opinion, did he ever get a FAA ThumbsUp, or is it just another ambulance chaser putting some wacky spin on an unclear legal text.

However, I did see that lawyer clearly spell out that he didnt see any comercial limits in flying models under AC91-57, as well as clearly say the FAA does control flying models- such control like giving them just a little area and restrictions on the types of control.

I was not happy with that lawyers interpretation of the G & E airspace, as well as his application of implied D, as to the effect on AC91-57 400'. Just because class G (Go for it) is under class E (Everywhere) doesnt mean you can do anything you want, say with a 260lb ultralight because it is in G. Even in G the part103 weight caps still count, unregulated is not really so, it is not Lawless


Anyhoo,
in respect to the OP, he should get insurance & do it legit
rather than under the table
