1) Mark the location of the metal mounting tabs on the bottom
of the stabilizer. Measure 3-3/16" (81 mm) from the side of the fin
on each side. This should be about the center of the hardwood rib
in the stabilizer.
From the elevator hinge line, measure 1-1/2"
(38 mm) forward.
The intersection of these two marks is the
mounting location for the metal mounting tab. Use a sharpened
awl to puncture the covering and a little of the hardwood rib. Use
two T2 x 6 mm PWA screws to mount the two metal tabs to the
bottom of the stabilizer, as shown.
❑
2) Adjust the two braces for length. They should both be 4"
(101 mm) long, measured from the pin of the R/C link to the
center of the bent eye at the opposite end. Lock this setting with
the knurled lock nut.
❑
3) On the bottom rear of the fuselage, measure 2-1/4" (56 mm)
forward from the rudder hinge line and make a mark on each side.
This is where the eye of the brace will be mounted to the fuselage.
Clip the R/C link to the tab on the stabilizer and position the eye of
the brace wire even with the 2-1/4" mark. Use a sharpened awl to
puncture the covering and wood at the center of the eye. Use two
T2 x 8 mm PWA screws to mount the braces to the bottom of the
fuselage. Remove the screws and swing the braces out of the way.
12
hinges and surrounding wood. Once sufficient time has passed,
move the rudder briskly left and right to free up its movement.

6) The pushrod connections are now made between the
elevators and rudder and their corresponding servos. Starting with
the elevator pushrod, slide a pushrod connector onto the elevator
pushrod wire. Now, install the pushrod connector stub into the last
outer hole in the elevator control horn and secure it to the horn with
the metal cup washer.
Repeat this procedure for the rudder
pushrod, installing the pushrod connector stub into the second
inboard hole in the rudder control horn, as shown.
Turn on your transmitter and power up the receiver with your flight
battery pack. Once again, check the rudder and elevator trims,
making sure they are at neutral settings. Hold the elevators in the
neutral position to the horizontal stabilizer, using a couple of small
pieces of tape applied to the outboard hinge lines.
With the
elevators now locked in neutral, use a screwdriver to firmly tighten
the setscrew in the elevator pushrod connector. Remove the tape
holding the elevators. Moving to the rudder, again use a piece of
tape to hold the rudder in neutral to the vertical fin. With the
rudder now locked in this position, use a screwdriver to firmly
tighten the setscrew in the rudder pushrod connector. Remove the
tape holding the rudder.
Use the transmitter to now test the movement of both the elevators
and rudder. If the movement of either of these surfaces in the
wrong direction, use the servo reversing function to change the
movement and, if necessary, re-center the surfaces to achieve a
neutral setting.
❑
7) The excess pushrod wire behind the pushrod connectors
can now be cut off, leaving about 3/16" of wire for any later final
flight trimming purposes.
