Please refer back to those pages for the proper tech-
nique for adjusting the control throws. These settings
will allow the airplane to fly smoother and make it
easier to control.
TEST FLYING AND TRAINING

❑
1) Check the operation of the throttle.
❑
A) Plug in your flight battery and turn on
the radio system.
CAUTION If you are using an ESC that is not
equipped with an arming switch, do not turn the re-
ceiver on unless the transmitter is turned on first.
Always turn the transmitter on first. Never allow
hands or clothing to get in the way of the propeller
when the radio is turned on. Sudden unwanted radio
signals, or turning the radio on with the throttle lever
set at full throttle, can turn the motor on unintention-
ally. Always make sure that the throttle lever is set
to idle before turning on the transmitter.
❑
B) If your ESC is equipped with an arming
switch, press the switch once to allow power to the
motor. When the throttle lever is at the idle position,
the motor should be off. Moving the lever should
turn on the motor. Gradually moving the lever to the
full forward position should result in the motor run-
ning at full power.
☛
Some ESCs will give you more proportional
control than others. Your ESC may also have a
manual control adjustment screw that must be ad-
justed prior to using the ESC. (Refer to your ESC's
operating guide for further information.)
❑
2) If you did not yet break-in the motor, refer to
page # 7 and follow the instructions for motor break-
in. Correct break-in will result in higher performance
and longer motor life. It is highly recommended.
PREFLIGHT CHECK
❑
3) Cycle the motor battery three times. When
NiCad batteries are new they need to be used 2-3
times before they will produce their top voltage and
duration. To cycle them, simply charge the battery
and then run the motor until the motor stops. Allow
the battery and motor to cool, then repeat this proce-
dure two more times.
❑
4) Check the condition of the transmitter bat-
teries. They should be fully charged if they are
rechargeable type NiCads, or replaced if they are non-
rechargeable cells and the voltage indicator drops out
of the green.
❑
5) Check every bolt and glue joint in the
Thermal-Air EP to ensure that everything is tight and
well bonded.
❑
6) Double check the balance of the airplane. Do
this with the flight battery securely mounted in the
airplane.
❑
7) Check the control surfaces. They should
move in the correct direction and not bind.
❑
8) If your radio transmitter is equipped with dual
rate switches double check that they are on the low
rate setting for your first few flights.
❑
9) Check to ensure that the control surfaces are
moving the proper amount.
❑
10) Check the receiver antenna. It should be
fully extended and not coiled up inside the fuselage.
SAFETY
The following are our general guidelines for your
safety and the safety of others. Please read and un-
derstand these safety guidelines before going out to
the flying field for the first time.
❑
1) Do not test fly your model for the first time
without first having it safety-checked by an experi-
enced modeler.
❑
2) Do not fly your model higher than approxi-
mately 400 feet within 3 miles of an airport without
having an observer with you. The observer should
tell you about any full size aircraft in your vicinity
and you should always give the right of way to full
scale aircraft.
