The rear of the seat-backs are closed using Depron or balsa, then the seams smoothed over
with light body-filler.
The seat-backs are then glued to the seat cushions.

NOTE:
Install the side panels with the base angled in slightly toward the fuselage center-line,
otherwise there will be a crack between the side and floor panels.

Before painting, the plastic surfaces should
be "keyed" with a light sanding or wiping
with Acetone (CAUTION: Acetone will
dissolve the plastic if too much is used!
Practice with a piece of scrap - very little is
needed for this step).
The mounting position of the cockpit floor is
determined by the base of the cockpit side
panels. To this end, the side panels -
consisting of a front and rear part – are
fitted. They are made up of a front and rear
part, which can be glued together and
The proper fit of the side panels to the
floor are best determined by trial fitting, as
shown here. Before painting, the
attachment points should be determined.
We recommend using small strips of hook-
and-loop material (ie. Velcro) to fix all of
the cockpit parts in place to allow access
to the fuselage radio/electronics area
when needed. For this, attachment
points/bearers (balsa or lite-ply strip) must
be worked into the fuselage (material not
included).
The photo illustrates the balsa bearers for
the one-piece side panels and the two floor
sections with seats. A few small sections
of hook-and-loop material are then glued
to the bearers. Use only small sections of
the material or you may have problems
getting the part out without damage.
NOTE: In this example, for balancing
reasons, the air tank, batteries, smoke
pump and power management system are
installed behind the last fuselage
