extension for the elevator servo and tuck the extension
into the fuselage.
3. Thread a 4-40 x 5/8 inch socket head screw into the blind
nuts. Use a 4-40 tape to clear the threads in the blind nut
if the screw does not thread in easily. Remove the screw
before proceeding.
4. Slide a #4 lock washer, the #4 washer on a 4-40 x 5/8-
inch socket head cap screw. Prepare all four screws at
this time.
5. Slide the stabilizer tight against the fuselage. Secure it
using two of the screws prepared in the previous step.
Use a 3/32-inch hex wrench to tighten the screws.
6. Repeat the previous steps to install the remaining
stabilizer.
