❑ 21) Install the M3 x 20 mm axle bolts and M3 hex nuts onto the
aluminum landing gear legs. Tighten securely. NOTE: If you have
some Loctite ® Thread Locking Compound around your shop, use
some here to eliminate any chance of the axles ever coming loose
in flight.
❑
22) Slip the main wheels onto the axle bolts and then thread on
the M3 lock nuts. Screw the lock nuts up close to the wheels, but
not actually touching them. Leave a little room so the wheels can
turn freely.
❑
23) Attach the assembled landing gear to the fuselage bottom
using the two M2.6 x 10 mm screws supplied. Notice that two
holes are pre-drilled in the bottom of the fuselage at the landing
gear location to accept the screws.
RADIO INSTALLATION:
For this section, you will need the piece of Velcro ® tape from the kit
contents, plus your micro receiver and charged flight battery pack
(see notes at the beginning of this manual about receiver and
battery specifications).
RECEIVER:
❑ 24) Using a piece of Velcro ® tape, mount the receiver directly to
the fuselage floor, just ahead of the fuselage former that is in front
of the servos.
❑ 25) Route the receiver antenna out of the fuselage. First, drill
position of the control horn hole on the wire.
NOTE: The wire will be installed in the 2nd hole from the
end of the horn.
c) Temporarily remove the elevator servo output arm from the
servo. This will allow you to pull the elevator pushrod
farther outside the rear of the fuselage, to make the next
step easier to do.
d) Use a pair of pliers to firmly grasp the pushrod wire at the
mark just made. Look inside the fuselage to make sure that
the Z-bend end of the pushrod is parallel to the jaws of your
pliers. What we're getting ready to do is bend the aft end
of the pushrod wire 90
O SIDEWAYS to the fuselage -
meaning, sideways when the servo arm is re-installed on
the servo. If needed, readjust your grip on the wire so that
you can bend the wire in the right direction. When ready,
bend the aft end of the pushrod wire 90
O . Make the bend
as sharp as possible.
e) The excess length of pushrod wire can now be cutoff,
leaving a 3/16" end leg to pass through the control horn
hole. Use a good sharp pair of wire cutters to do this.
f) Remove the tape holding the elevator in neutral position.
g) Insert the bent end of the pushrod wire in the hole in the
control horn. Then, slide the nylon pushrod keeper up to
the control horn and snap its tab end over the exposed
wire.
h) Re-install the elevator servo arm on the servo.
NOTE: Later, when you hook up and turn on your full radio
system for the first time, you may find that the length of the
elevator and rudder pushrods did not come out exactly perfect,
leaving the control surface slightly out of neutral position. If so, you
can make small corrections to the overall pushrod length by slight
tweaking of the "V-shaped adjustment bend" that is near the servo
end of the pushrod.
LANDING GEAR:
For this section you will need the aluminum landing gear, two main
wheels, two M3 x 20 mm axle bolts, two M3 hex nuts, two M3 lock
nuts, and two M2.6 x 10 mm screws.
