Ray,
The rivets are from my local hobby shop 1/16" shaft but I have purchased even smaller from Micro Fasteners in brass.
The rolled edge of the seats is a fake-out, it is actually a piece of aluminum tube slit and applied over the edge.
All the aluminum is .020" thick.
Noah,
Charlie does something I could never do; design these things; boggels the mind.
I need you to come up here and show me how to fly this thing, you are the only one with Moki / Avenger experience.
Larry,
Too cold.
Chic,
Were are you?
Charlie,
Thanks.
