One of the great things about the BD4 is the never exceed speed of
234 MPH. This means you can use a 350 HP turbo 2 rotor and cruise
at 200 MPH. That is far far better than  a  $750.000 brand new
Cessna 182.  You can probably get 90 gallons of fuel in it as well.
Vans airplanes have a never exceed speed of only 200 MPH. If you
install breathing oxygen you can do it at 18,000 feet as well with
out going IFR.

The BD4 is a high performance four place kit aircraft and as such
is a real bargain. Easy to build as well.

ZU - MBD take 210 Liters of fuel or 55, 4 us gallon The aluminum
metal skin is epoxying to the ribs with no rivets, sleek and low
friction laminar flow wing. Only the control surfaces have cherry
nut rivets. The endurance time with a 2 rotor "will bead your
bladders endurance in cruise configuration"!

I was thinking more of Oz where it is 3000 miles coast to coast.

When you put the skin on the wings how do you keep it down while
the epoxy cures?

Paul Lamar


The wing was imported from Bede corp completed.Think they epoxy the
rib flanges and then press the skin that is pre bended at the
leading edge in a jig.The wing hang on the spar horizontal with the
rib flanges upwards 90 degree's This process is done in a pre heated
room so that after curing of the epoxy the skin is very stiff and do
not tin can in the sun.

What was the cost of the wing?
