Sousa you wont give it a rest will you? Are these guys hurting you? It sounds too much like protectionism to me.
The rule of law will prevail in the end and someone will lose, someone will win. But instead of deriding the Huey and constantly complaining, why don't you guys compete. I reiterate; if someone wants an extreme (Vietnam) experience they are not going to be attracted to pretty 206s and ECs.
So buy a Huey and operate it according to the book, you too would make more money.
