To install the supplied Control Horns position the Trumpet
Base at the beveled edge of the Aileron and align with the
Aileron Push Rod and mark the location. Drill a 3/32 inch
diameter hole on these marks.
TIP: Strengthen the holes by applying a few drops of thin
CA Glue in both holes to reduce the amount of Balsa
compression.
Install the Trumpet Base with the Trumpet Screw and
Washer on the other side of the Elevator.
Do not over
tighten.
Install the Control Horn and Clevis on the Trumpet
Base. Thread the Aileron Push Rod into the Clevis and
make a “Z” bend” in the other end to install through
your Aileron Servo Arm.
Tip: Double check the length before making the “Z”
bend with the control surface at the neutral position.
Attach a Clevis to each Flap Push Rods and connect to each
Flap Servo Arm with a “Z” bend. Position the Hatch Covers
so the Push Rods goes through the hole in the trailing edge
of the Wing and connects with the Flap Control Horn
(already installed). Secure both Flap Servo/Hatch
Assemblies to the wing using 4 Small Wood Screws using
the same procedure as the Aileron Servo Hatch Covers.
Locate and cut holes in the Covering on both sides of
the Fuselage for the Wing Tube (1 inch), Wing Bolt (1/4
inch), Servo Leads (9/16 inch) and Dowel (1/4 inch).
Note: If the wing tube is excessively tight when you test
fit the Main Wings use some 600 Grit Sandpaper.
