❍
15. With Former F4 and Former F5 glued in position, apply
thin CA glue to all the joints, around the formers and along the
bottom. Keep checking the parts fit and alignment as you glue.
Wait a minute for the glue to set, then apply thick CA to the joints
to make sure a good bond exists, especially in the joints that do
not fit perfectly.
Note: The use of CA accelerator will be helpful when using thick
CA to fill any large gaps.
❍
16. Place the remaining Former F4 and Former F5 into
position inside the fuselage. Pull the fuse together against the
formers and tack glue them into position with Thin CA.
❍
17. Test fit the die-cut 1/8" balsa Fuse Top into position, making
sure the slot for the Rudder Pushrod Exit is on the left (looking
from the back to the front). Once satisfied with the fit of the fuse
top, remove it and run a bead of Medium CA along the top of the
Upper Fuse Rails from the front of the rail to in front of Former
F5. Place the Fuse Top back into position. After the CA has cured,
remove the fuse from the building board and run a bead of
Medium CA along the seam where the sides meet the fuse top.
Note: The section from F5 to the tail of the fuselage will be glued
after the Fin has been installed.

❍
18. Test fit the Firewall Assembly into position. Make sure it is
fully seated against the fuse doublers. Remove the firewall and
use 30-minute epoxy to glue it in position. Check the firewall
periodically to make sure it remains pressed tight against the
fuse doublers.
❍
19. Position the Main Landing Gear on the bottom of the fuse,
using the plans as reference. Place one of the Landing Gear
Straps onto the gear and mark the location of only one of the
holes. Drill the mark using a 1/16" drill bit, then secure the strap
with a #2 x 3/8" Sheet Metal Screw.
❍
20. Measure the distance from each tip of the Main Landing
Gear to the tail of the fuse. Adjust as necessary to make both
measurements equal. Once the gear is in position, place and
mark the locations for the remaining three Landing Gear Straps.
Drill 1/16" holes at the marks and secure the Main Landing Gear.
In total, you should have eight #2 x 3/8" Sheet Metal Screws and
four Landing Gear Straps. The Main Landing Gear may be
removed until after covering.
❍
21. Use Medium CA to glue the front fuse doublers to the
inside of the engine compartment.
BUILD THE WING
Note: The Tower Trainer 40 wing, much like the fuselage, is
designed with simplicity and ease of building in mind. Always
remember to test fit parts before using glue to make any
adjustments for the best possible fit.
