- The main fuselage member, like most of
the struts, is made from aviation grade aluminium tubing
- The wing beat lever is pivoted to
allow its forward end to move up and down
- The movements of the wing beat lever,
and hence the movements of the wings, are controlled by the beat
control cylinder
- The pilot is harnessed to a back
support and can sit on a padded saddle when not pumping the wings
|
- The hand controls operate the control
surfaces on the tail plane for pitch and turn. (These controls are
necessary because the pilot cannot use changes in body position for
control as in the case of a hang-glider.)
- The wing incidence bar carries the
wings and is pivoted at the back to allow incidence changes of the
wings during the beat cycle. During the upstroke the bar has a
positive angle of incidence, and during the downstroke the bar has a
negative angle of incidence
