5.2.2 Tail assembly Piper J-3 Cub
Glue L1 and L2 parts of the stabilizer and elevator. The profile is symmetric, so the left and
right sides are identical. Glue the stabilizers perfectly perpendicular to the fuselage. Assemble
both sides of the elevator with the elevator arm on a flat surface. Make a Z bend on the
elevator and rudder 0,5 mm pushrod wire. Mount the elevator assembly to the stabilizer
using the piece of PET filament. Elevator should move freely controlled by the pushrod and
servo. Glue rudder part together and mount to the fuselage by piece of PET filament. Check
the functionality of the elevator and rudder assembly carefully.
