❏
6. Fit a 5/32" [4mm] wheel collar into the nylon steering
arm, aligning the threaded hole in the collar with the hole
in the arm. Loosely thread a 6-32 x 1/4" [6mm] SHCS (with
threadlocking compound) through the hole in the arm and
into the collar. Install a brass screw-lock pushrod connector
using a nylon retainer into the outer hole on the steering arm.
Loosely thread a 4-40 x 1/8" [3mm] SHCS into the screw-
lock pushrod connector.
❏
7. Fit the steering arm between the nylon steering block
halves. Insert the nose gear wire up through the steering
block and through the steering arm as shown. Tighten the
SHCS against the fl at spot in the nose gear wire.
❏
8. Align the bottom edge of the steering block with the
bottom edge of the hardwood mounting plate on the fi rewall.
Mark the locations of the four steering block mounting holes
onto the hardwood plate. Drill 3/32" [2.4mm] holes at the
marks you made. Mount the steering block onto the hardwood
plate using four #4 x 5/8" [16mm] self-tapping screws, being
sure to harden the holes with thin CA.
❏
9. Cut off the threads from the remaining 12" [305mm]
pushrod, leaving all of the unthreaded portion of the
pushrod intact. Make a mark 3/16" [4.8mm] from one end
of the pushrod and make a 90° bend at the mark. Fit the
unbent end through the steering pushrod hole in the second
fuselage former and out the hole in the fi rewall. Fit the forward
pushrod end into the brass screw-lock pushrod connector on
the nylon steering arm. Insert the bent end of the pushrod
into the second inner hole in the unused side of the rudder
servo arm. Secure the pushrod onto the servo arm using a
nylon FasLink. With the rudder servo arm perpendicular to
the servo case, rotate the nose gear wire so that the nose
wheel is pointing straight. Tighten the SHCS in the brass
screw-lock pushrod connector against the pushrod.
