2. Working over the rudder portion of the plan,

place the laminated RUDDER TOP over the

plan and trim, if needed. When satisfied with

the fit pin in place.

Follow the same procedure for the laminated

RUDDER BOTTOM.

3. Using 3/8” square balsa, glue the rudder L.E.

to the rudder top.

4. Use 1/8 x 3/8” balsa sticks, as shown, to form

the trussing.

Complete the trussing. Then use 5/16 x 3/8”
balsa to form the rudder trailing edge.

HINGING AND ROUNDING

1. Referring to the plans, mark the hinge locations

onto the elevator.

2. Fit the stab and the elevator together and, use

balsa sheeting scrap to make a 5/64” spacer

between the elevator air balance and the stab.

Then, transfer the hinge locations from the ele-

vator to the stab.

3. Again referring to the plans, mark the hinge

locations onto the rudder.

As in the previous step, make a 5/64” scrap

balsa spacer between the fin and the rudder air

balance.

Transfer the hinge locations from the rudder to

the fin.

4. Using the CGP CENTERLINE MARKER,

scribe a centerline onto the elevator L.E.

Next, scrib a line onto the stab T.E.

Repeat this process with the rudder L.E. and

the fin T.E.
