2. Fit the servo tray into the fuselage. The tab at the front

of the tray slides into the slot in the former behind the wing
tube. Drill a 1/16" [1.6mm] hole through the two mounting
holes in the tray. Thread a #2 x 3/8" [9.5mm] self-tapping
screw into each hole and back it out. Apply a couple drops of
thin CA to each hole to harden the wood. When the glue has
dried, secure the tray inside the fuselage using two #2 x 3/8"
[9.5mm] self-tapping screws and two #2 fl at washers.

3. Thread a nylon clevis and silicone clevis retainer onto

a 2-56 x 36" [914mm] pushrod 20 complete turns. Slide the
pushrod through the rudder pushrod exit slot in the fuselage
and connect it to the second from outer hole in the rudder
control horn.

❏

4. With the rudder in the neutral position and the rudder

servo arm perpendicular to the pushrod, mark where the

pushrod crosses the outer hole of the servo arm. As you
did with the aileron pushrods, make a 90 degree bend at
the mark and cut off the excess pushrod 1/4" [6mm] beyond
the bend. Secure the pushrod to the servo arm with a nylon
FasLink. Make any adjustments necessary to the nylon clevis
so that the rudder is properly centered and slide the silicone
clevis retainer to the end of the clevis.

❏

5. Attach two 2-56 x 36" [914mm] pushrods with nylon

clevises and silicone clevis retainers to the third from outer
holes in the elevator control horns.

❏

6. With the left elevator in the neutral position and the

elevator servo perpendicular to the servo case, mark the
location where the left elevator pushrod crosses the outer
hole of the elevator servo arm. Make a 90 degree bend at the
mark and cut off the excess pushrod 1/4" [6mm] beyond the
bend. Position the right elevator in the neutral position and
cut off the excess pushrod 1" [25mm] behind the elevator
servo arm. Join the two elevator pushrods together using two
5/32" [4mm] wheel collars, two 6-32 x 1/4" [6mm] SHCS and
thread locking compound. View the model from behind and
confi rm that the elevator halves are parallel. If not, make any
adjustments as necessary to the clevises or wheel collars
until they are.
