Ron: This Fokker is one of my own design, much updated with modern airfoil,
ailerons,
different tailplane and such, but meant to look very much like original in
planform.
Since it's almost full size with 29' wingspan, it weighs in at 510 lbs empty,
and while
the flying wires do the major work in supporting wing loads, the forward and
aft spars
of each wing
fit 18" into two fuselage spar boxes, extending to each side, forming a short
midwing
center section, integral with the fuselage. The first is just forward of the
instrument
panel, the other on the aft cockpit bulkhead. Even in the event of a parted
wire, the
spars would still carry much of the load - kinda "belt and suspenders"
approach. With
the typical main support pylon, there are four turnbuckles attached at each
side, this
being the one area of contention when it comes time to dismount the wings.
Since I
really like the Flybaby, particularly a two place version, I am considering it
for a
next project, but I would really like to keep something on the field that I
won't have
to take down - just drive out to the airport and fly. Even towing the trailer
around
town with people creeping up to get a look makes one nervous. Not the time for
a fender
bender and aircraft crash all at once. The Fokker was featured in the Nov./Dec.
issue
of VW Aviation News. My thanks to Keith Schindler for such an outstanding
publishing
job.
