I'd love to see pics of that wing.
Question: Were the wings made and bonded in-house?
Question: What was the bonding process?
Question: Does the last batch of AG5Bs have the same wing? It looks more p
ointed to me.

What exhaust were you planning to use?
I guess if you went with the short PF you loose all the fins on one side.

---- I see Fletcher is still hand fabricating a metal cover. Do you think they
use an English wheel to make the compound curve?
