Position The Trike And Wing
Position the wing on its control frame, facing into the wind,
with the nose on the ground. The mast tube of the trike
should be held down using the strap as described above.
Check the ignition switches are off. Wheel the trike behind
the wing, rolling the front wheel over the control bar. Apply
the trike park brake.

Attach Mast To Wing U-Bracket
Figure 18 Section 4. Attach Wing to Wing U-Bracket
Allow the main tube to rise by loosening the strap until high enough to connect the universal junction to
the wing. Insert the bolt with bolt head retainer.
The standard position for the heart bolt through the U-bracket is below the arrow on the Hang Point
Placard on the keel roller. The heart bolt retainer is positioned in the other open hole to prevent rotation
of the bolt.
Tighten wing nut until seated and finger tight, then tighten another 1/2 turn using a small spanner /
wrench. Secure with safety pin. Remove mast-retaining strap from around the base tube and keel.

CAUTION
FAILURE TO TIGHTEN THE HEART BOLT ADEQUATELY WILL
ALLOW THE BASE TO YAW INDEPENDENTLY RELATIVE TO THE
WING RESULTING IN POOR HANDLING IN TERBULANCE
