Motor Installation:
41)
Install the motor on the firewall per the instructions
included with your particular motor. It might be necessary to
drill another hole in the firewall for motor shaft clearance.
To help prevent possible motor battery damage in the event
of a crash do not use motor mount screws that extend into
the battery compartment more than 1/16”. To help prevent
possible equipment damage or personal injury do not install
the propeller until AFTER all of the flight control rigging is
done. An E-Flite Power 32 is shown in the photo but a E-
Flite Power 25 is MORE than adequate for this model.
Control Surface Rigging:
42)
The control surfaces can now be rigged. Install the completed
gimbal assembly using the 3/32” x 1” wire and two wheel collars.
Remove the servo arm from the rudder servo if installed. Connect
the rudder servo and ESC leads to the receiver. Connect the
motor leads to the ESC. Turn on your transmitter and plug in the
flight pack battery. Determine if the servos are moving in the
correct directions and make any needed adjustments. Re-install
the rudder servo control arm with both the servo and rudder in
the neutral positions. Re-install the pitch and roll servo control
wheels as shown in Figure 1 of step 39. Drill a 3/16” hole in the
pylon hatch for the 4-40 pushrods as shown on the CAD
drawings. If you are using different servos or servo control
wheels you will have to calculate where to drill the holes. Install
a 4-40 ball link on both of the pushrods. Ensure that the threaded
portion goes at least half way into the link. Install the roll control
pushrod through the pylon hatch and with the ball link lined up
with fiberglass control arm (gimbal is neutral) mark the pushrod
so that about 1/4” will extend through the EZ connector. Remove
the pushrod and cut at the mark. Re-install the roll control
pushrod through the EZ connector and secure the ball link to the
fiberglass roll control arm. With the radio turned on and servos
and gimbal at the neutral position, tighten the set screw on the EZ
connector. Repeat the process for the pitch control pushrod but
set the distance from the pylon hatch to the ball link as shown in
the CAD drawings. Also note that the pitch pushrod has a very
slight bend at the servo end to compensate for the angle. See the
CAD drawing for details. The pylon assembly can now be
secured to the fuselage.
TIP:
If the paint on the gimbal causes the gimbal to 'stick' in the forks, apply a very small amount of talcum
power on the inside of the forks.
