XP652 MANUAL Important Information
IMPORTANT INFORMATION
Radio controlled models are a great source of
pleasure. Unfortunately, they can also pose a
potential hazard if not maintained and operated
properly. It is imperative that you install your radio
control system correctly. Additionally, your level of
piloting competency must be high enough to ensure
that you are able to control your aircraft under all
conditions. If you are a newcomer to radio controlled
flying, please seek help from an experienced pilot or
your local hobby shop.
Listed below are some safety Dos and Don’ts that must
be followed by all pilots:
• Ensure that your batteries have been properly
charged prior to initial flight.
• Keep track of the time that the system is turned on
so that you will have an idea of how long you can
safely operate your system.
• Perform a ground range check prior to the initial
flight of the day. See the “Daily Flight Checks
Section” below for information on how to do so.
• Check all control surfaces prior to each takeoff.
• Use frequency flags.
• Do not fly your model near spectators, parking
areas, or at any other area that could result in
injury to people or damage of property.
• Do not fly during adverse weather conditions. Poor
visibility can cause disorientation and loss of
control of your aircraft. Strong winds can cause
similar problems.
• Do not fly unless your frequency is clear.
Warning:
Only one transmitter at a time can
operate on a given frequency. If you turn on your
transmitter while someone else is operating a
model on your frequency, both pilots will lose
control of their models. Only one person can use a
given frequency at a time. It does not matter if it is
AM, FM or PCM
— only one frequency at a time.
• Do not point the transmitter antenna directly
toward the model. The radiation pattern from the
tip of the antenna is inherently low.
• Do not take chances. If at any time during flight you
observe any erratic or abnormal operation, land
immediately and do not resume flight until the
cause of the problem has been ascertained and
corrected.
1. Check the battery voltage on both the transmitter
and the receiver battery packs. Do not fly below
9.0 volts on the transmitter or below 4.7 volts on
the receiver. To do so can cause a crash of your
aircraft.
Note:
When you check these batteries, ensure that
you have the polarities correct on your expanded
scale voltmeter.
2. Check all hardware (linkages, screws, nuts, bolts)
prior to each day’s flight. Be sure that binding
does not occur and that everything is properly
secured.
3. Ensure that all surfaces are moving in the proper
manner.
4. Perform a ground range check before each day’s
flying session. The range check should be as
follows:
• Do not extend the transmitter antenna at this
time. Turn the transmitter “on.”
• Turn the model “on.”
• Slowly walk away from the model while moving
the control surfaces. The aircraft should function
properly at a distance of 75–100 feet.
5. Just prior to starting your aircraft, turn “off” your
transmitter and then turn it back “on.” Do this
each time you start your aircraft. If any critical
switches are on without your knowledge, the
transmitter alarm will warn you at this time.
6. Ensure that all trim levers are in the proper
location.
7. Check to be sure that all servo pigtails and switch
harness plugs are secured in the receiver. Also,
make sure that the switch harness moves
completely in both directions.
