SCOTT BLACK DESIGNED
this to be an inexpensive sport
aircraft that was easy to transport
and fly almost anywhere. The
prototype’s simple
construction consisted mainly
of scrap wood that Scott had
on hand.
For building ease, the
wing consists of ribs that are
identical except for the center
two. The wing LEs and TEs
are sheeted for additional
strength. The fuselage uses
formers and stringers and is
also sheeted, providing a
clean-looking airframe that is
a snap to cover.
This 42-inch-span model
was designed around a .25
glow engine, and it can
accommodate electric power.
The Indy 400 weighs
approximately 3.5 pounds
with an O.S. .25 FX engine
and standard-size servos.
Scott noted that the
aircraft required little rudder
work while on the ground and
could get airborne quickly.

design’s aerobatic capability,
and a bonus was that it
