Make yourself confident with
the parts. All items are
supplied with the kit. The photo
on the left shows a set of parts
and an assembled speed
brake door.
The next photo explains, how
the axle has to be placed.
Basically it is a 4 mm
aluminum tube, with flat ends,
curved according to the
fuselage’s shape. So, slide the
tube through the holes in the
ply mounts and shorten, crimp
and bend it as needed.
Fix the whole unit in the
fuselage, using only a few
drops of thick CA glue.
After you confirmed the
movement is alright you glue
all with epoxy and milled fibre.
To reinforce the bond you
should additionally cover the
bond with some scrap pieces
of fiberglass.
If necessary, you can now
sand the corners and edges
slightly. Especially in the hinge
area you might have to remove
some more material, to make
the door moving without
locking in this area.
After all is set, glue a small
strip of 0.8 mm plywood inside
the fuselage, at the rear end of
the speed brake door, as
shown in the photo.
