SERVO PRECAUTIONS
13A
S
• Do not lubricate servo gears or motors.
• Do not overload retract servos during
retracted or extended conditions.
Make sure they are able to travel their
full deflection. Overloading or stalling
a servo can cause excessive current
drain.
• Make sure all servos move freely
through their rotations and no linkages
hang up or bind. A binding control
linkage can cause a servo to draw
excessive current. A stalled servo
can drain a battery pack in a matter
of minutes.
• Correct any control surface "buzz" or
"flutter" as soon as it is noticed in flight,
as this condition can destroy the
feedback potentiometer in the servo. It
may be extremely dangerous to ignore
such "buzz" or "flutter."
• Use the supplied rubber grommets and
brass servo eyelets when mounting
your servos. Do not over-tighten the
servo mounting screws, as this
negates the dampening effect of the
rubber grommets.
• Ensure the servo horn is securely
fastened to the servo. Use only the JR
®
servo arm screws provided; the size is
different from other manufacturers.
• Discontinue to use servo arms when
they become "yellowed" or discolored.
Such servo arms may be brittle and
can snap at any time, possibly causing
the aircraft to crash.
•Check all related mounting screws and
linkages frequently. Aircraft often
vibrate, causing linkages and screws
to loosen.

Radio controlled models are a great
source of pleasure. Unfortunately,
they can also pose a potential hazard if
not operated and maintained properly.
It is imperative to 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.
Safety Do's and Don'ts for Pilots
• Ensure your batteries have been
properly charged prior to initial flight.
• Keep track of the time the system is
turned on so you will know 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" for
information.
• Check all control surfaces prior to
each takeoff.
• Use frequency flags.
• Do not fly your model near spectators,
parking areas or 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, and immediately
and do not resume flight until the
cause of the problem has been
ascertained and corrected. Safety
can never be taken lightly.
