If you made a belly pod that provided some lift could you not increase the

I think of this because at lease some of the pontoons on the market "carry
thier own weight" so to speak and don't subtract from the aircrafts useful
load.

I've always wondered about that. Seems to me that works fine in the
air (although any additional flat plate area will of course affect
overall drag), but what about landing?

Also, in order for the pod to not contribute to the gross weight of
the airplane, wouldn't it have to be able to produce it's lift at the
time of takeoff? And if it's doing that, will it add a lot of drag at
cruise?

I building a Zenith 601XL and it has a fairly thick wing. I was thinking use
the same front and main ribs and build one that was about 3 feet long. sure
there would be additional drag but there would also be additional lift. The
question is how much lift would a three foot piece of wing mounted under the
fuselage produce?

If it is enough to overcome the weight of the wing and say 80 lbs of cargo
there would be times that I could live with the lower airspeed, higher Vr
and higher stall.

P.S. Corky, your great to talk to when your not talking politics.
