from front to rear. Use the three mounting holes in the bracket as
a pattern. Drill three 1/16" dia. guide holes for each mounting
screw. Mount the secondary spring strut (first) and the main strut
arm to the bottom of the fuselage, using the three #3 x 15mm PWA
screws provided. Firmly tighten these screws. The two tailwheel
centering springs will be installed shortly.

8) The rudder is now hinged to the vertical fin. The method for
doing this is exactly the same as it was for the ailerons and
elevators, hinged earlier in this manual. After letting the CA glue
wick fully through the hinges and surrounding wood (about 10
minutes), flex the rudder firmly in each direction to create free and
easy movement.
The two nylon rudder control horns are now mounted in place, one
on each side of the rudder.
In case the bottom rudder hinge
interferes with the two horn mounting holes, use a 5/64" drill bit to
clear the holes. From the kit contents, locate two nylon control
horns, two M2 x 20mm Phillips head bolts and two M2 hex nuts.
Insert the two bolts through the mounting holes in one of the
control horns. Insert the two bolt ends through the two holes in the
rudder. Fit the opposite control horn in place onto the bolts and
secure the bolts firmly with the M2 hex nuts.

1) The 4-40 elevator pushrod is now made. Solder the 4-40
Solder Link to the unthreaded end of the pushrod.
Insert the
pushrod into the barrel of the solder link a total of 3/8" and make a
good solder connection.
Use two pieces of masking tape to secure both elevators tips in
neutral to the stabilizer. With the elevator servo extension cable
plugged into the receiver, turn the radio system on. Make sure the
elevator trim is also in neutral. Thread the 4-40 R/C link onto the
pushrod and attach the nylon control horn to the R/C link, using the
second hole from the tip. Attach the elevator servo output arm to
the solder link end of the pushrod, in its outermost hole. Press the
output arm onto the servo, facing up toward the stabilizer bottom,
at 90
O
to the servo, and rest the base of the control horn onto the
leading edge of the elevators.
Adjust the R/C link in or out on the pushrod, until the base of the
control horn sits exactly at the edge of the bevel line on the
elevators. With the base of the horn in this position, mark the
location of its two mounting holes onto the elevators, using a sharp
pencil or pointed object. Turn the radio system off and remove the
output arm from the servo, with the pushrod still in place. Remove
