TAIL CONSTRUCTION

Collect the following items

(2) Right & left Stab
(1) Small stabilizer tube

1.

Slide the small stabilizer tube into one side of

the stab. Then slide the assembly into the hole

in the fuselage till the stab is flush against the

fuse. (The side of the stab with the hole is the

bottom of the stabilizer). Slide the second stab

onto the tube sticking out the other side of the

fuselage. Squeeze both stab pieces together

firmly on to the fuselage. 

Check that the stabilizer is level with the wing.

Shim the tube in the fuselage up or down if

necessary. Do not go any farther till the stab is

level to the wing.

The Stabilizer can be mounted to the

fuselage two ways:

One way
1.

Using 4-40 bolt, drill and tap the stabilizer tube

at the hole location. This method will allow

you to remove the stab as needed. 

CAU-

TION

:You must watch the bolt holes for

fatigue and drill another hole by rotating the

tube when this happens.

Second way (Suggested)
1.

Draw a outline where both stabilizers meets

the fuselage side. 

Remove
covering

2.

Remove the covering with out cutting into the

wood below.
Make a mixture of epoxy and glue both the

tube into the stabilizers and the stabilizers to

the fuselage sides. Do this on both sides of

the fuselage where the stabs touch.
