Great Planes Extra 300S 1.60 ARF - GPMA1365 - Manual (Page 10)

Note: Because of the wide variety of engine combinations
and the varying weight of the engines you can use for this
airplane, we have designed a convenient place to add
weight to the tail should you find that tail weight is needed.
Weight can be attached to the bottom of the cover with
epoxy.
Install the cover now but when you balance the
airplane on page 19, should you need to add weight to the
tail, this is the place to install the weight.
❏
1. Position the fuselage cover in place on the bottom of
the fuselage. With the cover in place, drill a 1/16" [1.6mm]
hole through the cover and the plywood plate.
❏
2. Enlarge the holes in the cover only by drilling them out
to 3/32" [2.4mm].
❏
3. Install then remove a #2 x 3/8" [3mm] sheet metal screw
into the hole in the plywood plate. Put a couple of drops of thin
CA into the hole to harden it and allow the glue to cure.
4. Install the cover onto the fuselage and secure it with two
#2 x 3/8" [3mm] sheet metal screws and two #2 washers.
❏
1. Located on the bottom, rear of the fuselage is a plywood
mounting plate. Position the tail wheel assembly so that the
rearward mounting hole is 1/2" [13mm] from the end of the
fuselage. Drill a 5/64" [2mm] hole through each of the mounting
holes in the tail wheel assembly. Mount the tail wheel assembly
to the plate with two #4 x 5/8" [16mm] sheet metal screws.
❏
2. Parallel with the axle, file a flat spot for the steering arm
set screw on the end of the tail wheel wire.
❏
3. Using the hardware included in the bag with the tail
wheel assembly, install the tail wheel to the axle with two
wheel collars and set screws. Attach the wire to the tail
wheel assembly with a wheel collar and set screw and the
steering arm. Be sure the set screw on the steering arm is
tightened against the flat spot you filed on the wire.
❏
4. Locate the aluminum landing gear. Install the gear
onto the bottom of the wing with five 8-32 x 1/2" [13mm]
socket head cap screws. Apply a small drop of thread
locking compound to each bolt before screwing them into
the landing gear.
