Step 4. Mix a small amount of 30-minute epoxy and lightly coat

the inside of the threaded holes and the 8-32 x 2" Rocket City

screw. From the top of the elevator, thread the 8-32 screws into

the tapped holes and tighten. Wipe away any excess epoxy with

rubbing alcohol and paper towels.

Step 5. Screw the molded swivel link onto the 8-32 screw until

the distance from the elevator surface to the bottom of the link is

/8". Repeat this for the other elevator.

Step 6. Glue the elevator hinges in place using the same

techniques used to hinge the ailerons. After hinging the elevator,

use the same technique to seal the elevator’s hinge gaps. Use

White UltraCote

for the bottom of the elevator. You can

substitute Clear UltraCote

if White is not available.

Step 7. Notice that the longer of the two tail tubes has a hole at

each end and that a hole is located near the center of the stab on

the top. It may be covered with UltraCote

. If so, use a #11 knife

blade to remove the covering over the hole. A 4-40 x

/8" socket

head screw and split washer are threaded through the hole in the

each half of the stabilizer and into the tail tube. This securely

fastens the stab to the fuselage.

Step 8. Insert the longer of the two tubes into the rear hole in

the stabilizer root. Carefully align the hole in the tube with the

hole in the stab. Thread the 4-40 socket head screw and split

washer into the hole securing the tube to the stab.
