5 . The wheels can be retained in one of two ways. As

shown, simply soldering 1/8" I.D. washers in place
will do the job. A more realistic method is to fit the
axle legs with lengths of 1/8" I.D. brass tubing,

soldered in place. With the axle holes of the wheels

drilled out to fit over these pieces of tubing, the
wheels are slipped in place. Next, slip a washer over

the tubing, against the wheel. Now drill a small
diameter hole through the end of the brass tubing
and insert a small cotter pin to retain wheel. Note
that the length of the M.W. L/G axle should be

shortened first, using a carbide cut-off wheel on your

Moto-Tool.

II.REARTAILSKID

1 . From your kit box, locate the 1/16" dia. x 22" length of

M.W. and the 1/16" pre-bent skid support wire. Note the
side and bottom view of this assembly, shown on

Plan Sheet 2. Use the pattern to now bend the 22"
length of M.W. to shape—easily done with pliers.
Neatly wrap the rear tip of the skid with soft copper

wire, apply flux and solder.

2 . Now tape the main skid wire assembly in place to the

bottom rear of the fuselage, at the cross brace, just
behind D-D. Use tape to now locate the pre-bent skid
support to the bottom, rear fuselage location shown.

Use soft copper wire to neatly wrap the support wire
to the tailskid, apply flux and solder. Remove the

completed tailskid assembly from the fuselage. This
assembly should be attached to the fuselage just
prior to painting or staining the exposed spruce
fuselage longerons, cross braces and uprights. We
have used and suggest black carpet thread or fishing
line for attachment.

3 . Should you wish to make this skid steerable, we've

provided an illustration of how we did it. This
assembly is essentially the same as the non-
steerable one just made, except that the rear part of

the skid is separate and is sleeved in a 1/16" I.D. length
of brass tubing. An arm is bent, at right angles, at the
top and another length of 1/16" I.D. tubing is soldered in

place. The end of this piece of tubing is flattened and

drilled with a hole to accept a nylon clevis. Now the

rear part of the skid becomes steerable when a se-
cond threaded pushrod and nylon clevis are attached
to the rudder pushrod. Note that the parts for this op-
tion are not supplied with your kit.
