Primarily replacing the fat, high-drag styrofoam fuselage with a
pod-rod scheme. I discovered the need for this when I flew the
styrofoam wing on my Corndogger's pod-rod fuselage. It flew almost
as good as the Corndogger's stock wing. I modified the wing by
(1) feathering the wing's squared off trailing edges, (2) cutting
the roots of the two wing halves to remove the sweep so it would
be straight like most other glider wings, (3) glueing the wing
halves together with an 8" dowel inside to preclude "flapping" and
"pigeon wing" (45 degree dihedral) caused by the stock attachment
method. I now attach the wing with rubber bands.
The next improvements will be (1) sanding some undercamber into the
bottom of the wing, (2) using 1/16" epoxy-fiberglass printed
circuit board to build a super strong pod box and then covering
it with a thin plastic streamlined cowling to reduce drag. I'll
use a fiberglass or carbon fiber kite stick for the rod and a foam
rubber shock absorber on the nose. I always use a rubber band
mounted, break-away tail assembly.
The idea behind the styrofoam glider was to minimize cost and
building time so you wouldn't worry about crashes. It's
surprisingly rugged too and damage can usually be repaired at the
field with clear shipping tape. Those factors alone make it a
pretty good trainer even though it doesn't fly as well as other
gliders. I get a big kick out of letting kids and other novices
fly it. (That 50' hill I fly at is on a school playground.) My
strategy now is to improve ruggedness and performance while
minimizing cost, building time and repair time.
