3) Slide the adjustable servo connector/
throttle arm assembly over the end of the throttle
pushrod wire. Position the throttle stick and the
throttle trim at their lowest positions.
o
4) Manually push the carburetor barrel fully
closed. Angle the servo arm forward about 30º from
center and attach it to the servo. The arm should face
the right side of the airplane (looking from the rear).
With the carburetor barrel fully closed, tighten the set
screw in the adjustable servo connector.
o
5) Remove the excess throttle pushrod wire
using wire cutters. See photo # 36 below.

o
6) Test the movement of the throttle push-
rod. Full forward stick and full forward trim should
result in the carburetor barrel opening completely.
Full back stick and full forward trim should result
in the approximate idle setting. Full back stick
and full down trim should result in the carburetor
barrel closing fully.
o
7) When satisfied that the pushrod linkage
is adjusted correctly and no binding is present,
install the servo arm set screw.
PARTS REQUIRED
RUDDER PUSHROD
INSTALLING THE RUDDER CONTROL HORN
o
{1} Nylon Control Horn w/Nylon Back Plate
o
{2} 2mm x 15mm Machine Screws
o
{1} 990mm Nylon Pushrod
o
{1} 1.5mm x 45mm Wire Threaded Both Ends
o
{1} 1.5mm x 50mm Threaded Wire w/Z-Bend
o
{1} Nylon Clevis w/1.5mm I.D. Hole
o
1) The centerline of the rudder control horn
is located on the left side of the rudder (looking
from behind) 1-3/8” up from the bottom of the
rudder. Position the control horn so the clevis
attachment holes are directly in-line with the hinge
line. The control horn should also be parallel with
the hinge line. See figure # 6 at top right.
Figure # 6
o
2) When satisfied with the alignment, use a
3/32” drill bit and the control horn as a guide and
drill the mounting holes through the rudder.
o
3) Mount the control horn to the rudder by
inserting the 2mm x 15mm machine screws
through the control horn mounting base, through
the rudder and into the backplate. Tighten the
screws, but do not overtighten them. You do not
want to crush the wood.
o
4) Thread the 1.5mm x 45mm threaded wire
into one end of one nylon pushrod. For safety,
thread the wire no less than 5/16” into the pushrod.
o
5) Thread the nylon clevis onto the oppo-
site end of the 1.5mm x 45mm threaded wire. It
should be threaded no less than 5/16” onto the
wire also.
o
6) Using a modeling knife remove the cov-
ering from over the rudder pushrod exit slot.
Looking from the back of the airplane, the slot is
located on the left side of the fuselage, 1-7/8”
forward of the rudder hinge line and 3/4” below
the horizontal stabilizer.
o
7) Insert the plain end of the nylon pushrod
into the fuselage from the back. Snap the clevis
onto the rudder control horn. Move the rudder
back and forth to ensure there is no binding. See
photo # 37 below.
