It is highly recommended that you do not use any
more elevator or aileron control throw than what is rec-
ommended. Because the F-22 Raptor EP uses full-flying
stabilators, it doesn't require as much control throw as
you may be used to. Excessive control throws will only
cause over-controlling that will lead to a crash.
❑
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 receiver on unless
the transmitter is turned on first. Always turn the trans-
mitter 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 stick set at full throttle, can turn the motor on un-
intentionally. Always make sure that the throttle control
stick 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 control stick is at the idle position, the
motor should be off. Moving the stick forward should
turn on the motor. Gradually moving the stick to the full
forward position should result in the motor running 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 adjusted prior to using the
ESC. (Refer to your ESC's operating guide for further
information.)
PREFLIGHT CHECK
❑
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.
❑
3) Cycle the flight battery three times. When NiCD
and NiMH 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 procedure two more times.
❑
4) Check the condition of the transmitter batteries.
They should be fully charged.
❑
5) Check every bolt and glue joint in the airplane 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 fuse-
lage and the canopy installed.
❑
7) Check the control surfaces. They should move
in the correct direction and not bind.
❑
8) Check to ensure that the control surfaces are mov-
ing the proper amount.
❑
9) 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 understand 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 with-
out first having it safety-checked by an experienced
modeler.
❑
2) Do not fly your model higher than approximately
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; you should always
give the right of way to full scale aircraft.
❑
3) When flying at a flying field with established
rules, you should abide by those rules. You should not
deliberately fly your model in a reckless and/or danger-
ous manner.
❑
4) While flying, you should not deliberately fly be-
hind the flight line. If your model should inadvertently
fly behind the flight line, you should change course im-
mediately.
❑
2) After you have become familiar with the flying
characteristics of the F-22 Raptor EP, you may want to
increase the control throws to the settings listed below.
SPORT FLYING
Pitch: 3/4" up 3/4" down
Roll: 3/4" up 3/4" down
Because of the increased amount of control deflection
using the Sport Flying control throws, we suggest pro-
gramming 50% Exponential in both the elevator and
aileron controls (if your radio system offers exponen-
tial programming). Exponential will soften the controls
around center, which will help the airplane fly smoother
and make it less likely that you will over-control it.
