Preflight at the Field
1. Before each flying session, be sure to range check your
radio. This is accomplished by turning on your transmitter with
the antenna collapsed. Turn on the radio in your airplane. With
your airplane on the ground, you should be able to walk 30
paces (75’ to 100’) away from your airplane and still have
complete control of all functions. If not, don’t attempt to fly!
Have your radio equipment checked out by the manufacturer.
2. Double-check that all controls (aileron, elevator, throttle,
rudder, etc.) move in the correct direction.
3. Be sure that your batteries are fully charged, per the
instructions included with your radio.
4. Completely read the instructions included with your engine
and follow the recommended break-in procedure. At the field,
adjust the engine to a slightly rich setting at full throttle and
adjust the idle and low-speed needle so that a consistent idle
is achieved. Before you fly, be sure that your engine reliably
idles, transitions and runs at all throttle settings. Only when
this is achieved should any plane be considered ready for
flight.
Setting up Dual Ailerons and Flaps
Non-Computer Radio
The Hangar 9 Cessna has two aileron and two flap servos. Use
a Y-harness to connect the two aileron servos to the aileron
port of the receiver. The Y-harness splits the signal and moves
the ailerons in opposite directions. You will also need to use a
Y-harness to connect the flap servos to the flap port of the
receiver, but in this case you will need to use a reversed servo
for one of the flaps, as you want the flaps to move in the same
direction. Another option for the flaps would be to use a JR
MatchBox™(JRPA900) to run the flaps. The MatchBox can be
used to run up to 4 servos through a single port in your
receiver. It allows the adjustment of the servo’s center and end
points as well as reversing of the servos. The MatchBox would
eliminate the need for a reversed servo as well as making flap
setup a breeze.
Computer Radio
When using a computer radio you will connect one of the
aileron servos to the aileron port of the receiver and then mix
the opposite aileron to an auxiliary channel, generally the aux 1
channel. Most modern computer radios have a pre-mix for dual
aileron setup. For setting up the flaps you will connect one flap
to the flap channel and then mix the other flap servo to an
auxiliary channel similar to what you did for the dual aileron
servo setup. For ease of setup you may want to use a JR
MatchBox™ (JRPA900) to run the flaps. The MatchBox can be
used to run up to 4 servos through a single port in your
receiver. It allows the adjustment of the servo’s center and end
points as well as reversing of the servos. The matchbox would
eliminate the need for a reversed servo as well as making flap
setup a breeze.
Caution: Do not inadvertently skip these steps!
Recommended CG Location
An important part in preparing your Hangar 9
®
Cessna
aircraft for flight is properly balancing the model. This is
especially important when various engines are mounted.
The recommended Center of Gravity (CG) location for
the Hangar 9 Cessna Skylane 182 is 4" behind the
leading edge
of the wing measured at the fuselage sides. If necessary,
move the battery pack or add weight to either the nose or
the tail until the correct balance is achieved. Stick-on
weights are available at your local hobby shop and work
well for this purpose.
The following control throws offer a good place to start with
your first flights on the Hangar 9 Cessna. We recommend
only one rate setting for Cessna. As you become more
familiar with the handling of you model you may wish to
add a second rate setting.
