RUDDER ASSEMBLY

£ 

1  The rudder core sheet (RC) has a ply trailing edge (RTE) similar to the elevator core sheets. Assemble 

the rudder core sheet.

£ 

12 Cut two hinges in half lengthwise to produce four 

1” x 3/8” hinges. Install these to the elevators and 

stabilizer at the locations indicated on the plans. 

Do not glue until after covering. This concludes 

the stabilizer/elevator assembly.

RIGHT

The completed stabilizer and elevator assembly ready for cov eting 

and  then  installation  on  to  the  fuselage  assembly. Assure  that  the 

hinges work freely and that the elevator counterbal ance protrusions 

do not bind, allow for covering material.

£ 

2 Install R1 through R6.

£ 

3 Install the rudder leading edge RLE. Install R8 and R9.

£ 

4 Install the rudder horn caps RHC.

£ 

5

Sand or plane a 20° angle on the rudder leading edge for hinge clearance.

£ 

6

Cut a 5/8” length of 1/8” brass tube. Crush flat about 3/16” at both ends. Drill a 1/16” hole in both ends 

about 3/32” from the end. Bend the 1/16” M.W. rudder torque rod and slide the one end of the brass tube 

onto the end of the torque rod. Solder in position at 90° to the bend. Do not install permanently in the 

rudder until after covering.

VERTICAL FIN ASSEMBLY

£ 

1

Assemble the three fin core sheet sections. 

Use the same technique as you did on the 

stabilizer core sheet assembly.

£ 

2 Install ribs V-1 through V6. Use a straight 

edge to assure that V-1 is straight and at 

90° to the core sheet. This will provide the 

platform of the fin that will attach to the 

fuselage top and must be flat.

Like the stabilizer and elevator assembles, the vertical fin is built on a core sheet. Shown 

here are the three sections of the vertical fin core sheet ready to be assembled.
