Now you can install the mounting
plates for the gear door cylinders,
which are made from 3mm plywood
and are glued to the bottom of the
wheel bay. The length and the stroke
of the Robart Cylinders is perfectly
right. There is no room for an
additional clevis, but a 90 degree
bend of the 2mm pushrod, screwed
all the way into the piston rod of the
cylinder, works perfectly.
We recommend to screw the mounts
for the Robart cylinders directly on
to the plywood board and cut the
screw tip off. Then take the
assembled unit, confirm the correct
location and glue in with epoxy.
Usually you do not have to remove
the mounts anymore, you only have
to make sure that you can access the
e-clip for the pin at any time, to
remove or replace the cylinder, if
necessary one day.
Set the end positions so that the
cylinder still has about 1 mm
available travel when the gear door
is mechanically closed. This will
hold the gear door tight during
flight. When the cylinder is fully
extended, the angle of the gear doors
should be perfectly right, too. We
designed the hinges and control
horns matching the dimensions and
stroke of these cylinders.

snug wheel well, covered with tightly fitted gear doors.
