.
47. When the right wing is finished, sand both wing panels smooth and sand the leading edge round.
48.
Test fit the right and left wing panels together. With one wing panel on your building board you should have approximately 4
1/2" to 4 3/4" dihedral for the three channel wing and approximately 4 1/2" to 4 3/4" dihedral for the four channel wing. Now
glue the two wing panels together.
49.
Use thin C/A glue to attach the 1" nylon tape to the joint between the wing panels. Glue one end at the top trailing edge with
a small amount of glue. Now stretch the tape around the wing tightly and glue the tape completely into position. When the
glue is dry you can trim away any excess and then lightly sand the tape smooth.
50.
Cut the 3/4" triangle for the wing tips in half and glue to the ends of the wing. The front of the tip block should be flush with
the leading edge, and the bottom should be flush with the bottom of the W-2 rib. Glue a scrap piece of 3/32" sheet on top of
the wing tip to bring the middle part up to the height of the W-2 rib. Sand the tip blocks to match the airfoil section of the ribs
and then sand them smooth.
51.
If you are installing ailerons, cut 1/4" square notches in the ribs on either side of the aileron servo and mount 1/4" spruce
servo rails as shown on the plan. Trim the ailerons to the shape shown and temporairly hinge them to the wing.
Pre-Cover Assembly
52.
Sand the entire fuselage smooth and lightly round the corners.
53.
Install the main landing gear wires into the fuselage and secure with the landing gear straps (F-19) and #2 sheet metal
screws.
54.
Fit and glue the servo rails into position. Adjust the spacing of the rails to fit the servos that you are using. The servo rails
are made from 1/4" sq. spruce. The servo rails extend completely across the fuselage and rest on top of the F-2 s. Now
mount the servos on the rails. Mount three servos if you are building the glow powered version and only two servos if you
are building the electric powered version.
55.
Trim the wood from the rear of the stabilizer slot. Glue the stabilizer, fin and R-4 to the aft end of the fuselage. Make sure
they are straight and square before gluing.
56.
Temporarily hinge (do not glue) the elevators to the stabilizer.
57.
Cut the lower hinge slot in the rudder and the fuselage and then temporarily hinge (do not glue) the rudder to the model.
58.
Attach the control horns to the elevator and rudder with 2-56 screws. Install the rudder and elevator pushrods with clevises
at the horns and servo connectors at the servos.
Electric Powered Version
If you are building the Glow Powered Version, Skip ahead to step #67.
59.
Laminate two pairs of parts EM to make two motor mount rails. Now securely glue these rails to the front of the model. The
parts EM interlock with F-16E and the tabs fit into the slots in parts F-17.
60.
Assemble the gear box onto the front of the motor. Use the middle size pinion so that you have a 2.5:1 gear ratio. You
should apply blue Locktite to all screws and they should be securely tightened.
Note: Insert a 1/4" wide strip of typing paper between the gears while installing the gear box. This will provide the proper
amount of backlash in the gears when it is removed. You must apply a small amount of grease to the gears. Also, you
should check all components of the electric drive system for tightness before every flight and as the gears wear it may be
necessary to adjust the gear box to maintain the proper mesh between the gears.
61.
Attach the electronic speed controller to the motor and solder connectors to the speed controller to match the battery that
you are using.
62.
Lay one of the motor mounts on the EM rails. Feed the wiring from the motor through the hole in F-16E and then rest it on
the motor mount. Place the top half of the motor mount into position and press down to hold the motor into position.
