2. Position the retract against the wood mounting
bracket so the bottom of the retract is flush with the
bottom of the bracket. Drill a 1/16" hole through each
of the mounting holes. Then, install the retract to the
mounting bracket with four #2 x 3/8" [10mm] screws.
❏
3. Install a 2-56 nut, 2-56 threaded clevis and
silicone clevis retainer onto a 2-56 x 36" [914mm]
threaded rod. Install the clevis into the outermost
hole in the arm of the retract.
❏
4. Insert the threaded rod and retract unit into the
rear of the fuselage, sliding the rod into the plastic
tube in the center of the fuselage. Attach the retract
to the fuselage by inserting two 4-40 x 1/2" [13mm]
socket head cap screws and #4 flat washers through
the two holes in the bottom of the fuselage, attaching
the mounting plate and retract to the plywood plate
with pre-installed blind nuts inside of the fuselage.
Mount the tail wheel to the landing gear with a 3/32"
[2.5mm] wheel collar and 4-40 set screw on each
side of the wheel.
Tail Wheel Door Installation (Retractable)
The following steps cover the installation of the tail
wheel doors. This is optional and not required for
flight performance. If you fly from a grass field that is
very rough or has long grass, you might wish to omit
the installation of the doors due to the amount of
clearance between the doors and the ground.
❏ ❏
1. Locate the fiberglass tail wheel doors and
four pinned hinges. Place the doors into the opening
aligning the simulated stringers on the fuselage with
the doors to determine which door is the right and left.
❏ ❏
2. On the backside of the door make a mark
1/2" [13mm] in from each end of the door.
