Landing Gear Installation

1.

Collect the following items:

(1) Landing gear

(3) 6-32 x 3/4” socket head screws

(3) 6-32 blind nuts

(3) #6 washers

(1) Fuselage

2.

Place the main gear on the bottom of the

fuselage, as shown.

Locate the center of the fuselage and mark

it. Then mark the center of the gear and line

up both center marks.

3.

Move the gear back until it touches the stop on the

back of the gear block. Then mark the hole loca-

tions and drill a 5/32” hole at each location.

4.

With the screws and the washers through

the gear, pull the blind nuts up tight inside

the fuselage.

2.

Take three hinges and, as with the aileron

hinge installation, insert the hinge into the

elevator, using straight pins to ensure the

hinge stays centered between the stabilizer

and the elevator.

Slide the exposed side of the hinge into the

slots in the stab until the pins touch both the

stab and the elevator.

3.

Holding the elevator and stab together, place

a straight pin between the stab and the ele-

vator, at the elevator tip. This pin will create

a 1/32” gap between the elevator and the

stab. 

Remove the pins in each hinge and, keeping

the elevator/stab assembly in position, apply

3 or 4 drops of thin CA to each hinge, on

both the top and bottom sides of the stab.

Allow ten minutes for the CA to cure before

flexing the elevator.  Then install the second

elevator.

4.

When the elevators have cured, install the

hinges and mount the rudder, using the

same techniques used for the other hinged

surfaces.

NOTE:

Before gluing, make sure the top of the rud-

der is even with the top of the fin.
