Step 5: Nose Gear Door and Cylinder Installation
Note: If your model came with factory installed gear doors skip this step.
The order in which the doors are installed is up to the builder; this manual will start with the front
single door, and then proceed to the two double doors.
‰
If required cut out nose gear opening with a Dremel cutoff wheel or other appropriate means
to allow for gear door installation. Make sure that a lip is remaining after the final sanding to
size is completed, see photos 49.
‰
The doors may require some minor trimming to fit the fuselage opening, also a bevel may
need to be sanded on the hinge side of the doors to clear the lip in the fuselage, make any
adjustments that are required during the fit up of the doors.
‰
The hinges are installed on the right side of the front single door, see photo 50. The right
side is assumed to be viewing the fuselage from the rear and it is sitting on the gear. Due to
the geometry of the hinge locations the front doors may require a small wedge (see photo
52) to be placed between the door and the hinge in order to gain the required clearance to
open.
‰
After locating the hinge positions mark and drill the holes in the door and the fuselage.
‰
The front most hinge on the on the single large nose wheel door will need the extended tab
removed from the hinge to allow clearance for the tires when the gear is retracted. This can
easily achieved with a Dremel cut off tool.
‰
Install the two back nose doors using the same type of procedures as described for the
single door, except the back two doors should not require the wedge between the doors and
hinge. See photo 51.
‰
Door cylinder installation, the front door cylinder is installed on the right side of the fuselage
and is mounted to the rear hinge.
‰
To get the proper location of the wooden mounting block connect the cylinder rod to the
door hinge; temporarily connect the other end of the cylinder to the wood mounting block.
Blocks shown in photo 53.
‰
Extend the rod completely and hold the front door to its maximum open position, mark the
location of the wood block on the inside of the fuselage, position is shown in photo 54
‰
Prep the area where the wood block will be bonded to the fuselage by lightly sanding,
disconnect the cylinder and glue the block to the fuselage with adhesive. The block should
be held in position with masking tape or other appropriate means until completely cured.
‰
When the mounting block is cured make the final attachment with the supplied hardware,
Loctite® should be used to prevent the screws from coming loose, be careful to keep the
Loctite® from contacting plastic parts as it may cause them to become brittle.
‰
The door cylinders for the two rear nose wheel doors are connected to the front hinges and
may require a spacer between the hinge and cylinder attachment point. The spacer may be
required in order to keep the cylinders in a perpendicular position to the bulkhead, see photo
56.
‰
The other end of the cylinders for the two front doors are attached to the wooden mounting
blocks that are bonded to the top side leading edge of the rear equipment tray, see photos
54 & 55.
‰
To set the mounting block position, temporarily attach the cylinders to the front hinges, and
then extract the cylinder rods fully. The front mounting tray will need to be fastened in
position.
‰
Open the two doors and hold in their full open position while positioning the mounting blocks
in their appropriate position. Mark the mounting position on the tray and also mark where
the cylinder mounting screws will be drilled into the blocks.
