16. Saturate the balsa with thick CA glue where the threaded
rods contact the balsa pushrod.
❑
17. Slide a piece of heat shrink tubing over the end of the
balsa dowel and shrink it in place as shown using a heat
gun.
❑
18. Locate one of the unthreaded rods and insert the 90°
angle into the opposite end of the balsa dowel. Using
thick CA, adhere the rod to the balsa dowel and heat
shrink it in place.
❑
19. Repeat this process to complete the other pushrod. Note
that only one threaded rod is necessary.
❑
20. Carefully cut away the covering at the tail of the fuselage
where the pushrods exit. Note there are two cut-outs on
the left side (top cut-out for elevator, bottom cut-out for
rudder) and one cut-out on the right side (elevator).
❑
21. Spread the two threaded pushrods apart about 2”. Insert
the elevator pushrod into the fuselage so that each
threaded rod comes out the elevator pushrod exit. Thread
a clevis onto each of the threaded rods 16 turns. Attach
the clevis to the second outer-most holes in the elevator
control horns.
Note:
As extra insurance, it is a good idea to place a piece of
fuel tubing over the clevis to prevent the clevis from accidentally
coming open.
