CONTROL STICK LENGTH ADJUSTMENT
NECK STRAP ATTACHMENT
There is an eye hook on the front of the transmitter for attaching an
optional neck strap. The eye hook is precisely positioned (see Section 3.2) so that the transmitter will be perfectly balanced when a neck strapisused.
To adjust the control stick length, use a 2mm Allen wrench to unlock
the set screw located inside the end of the control stick. Turn the set
screw counterclockwise to loosen it, then turn the knurled portion of the
stick to adjust the length. Counterclockwise will lengthen the stick and
clockwise will shorten it. After the control stick(s) has been adjusted to
suit your flying style, tighten the set screw.

BATTERY CHARGER
The pilot lamps on the battery charger should always be on during the
charging operation. If they are not, check to make sure you have
turned off both the transmitter and receiver.
Do not use the charger for equipment other than this system. The
charging plug polarity may not be the same and equipment damage
may result. Do not use other manufacturers’ after-market accessories
that plug into the transmitter’s charging jack. If you do, any damage
that results will not be covered by the warranty. If you are unsure of
compatibilities with your radio, seek expert advice before doing any-
thing to avoid possible damage. During the charging operation, the
charger’s temperature is slightly elevated. This is normal.
Special note on EXPERT transmitter charge polarity:
7. CHARGING YOUR EXPERT RADIO SYSTEM PRIOR TO INSTALLATION
Your EXPERT Radio System is shipped from the factory with both the
transmitter and receiver NiCad batteries in a discharged state. Before
attempting to install/operate your EXPERT system, it is important that
the system be charged for approximately 24 hours to ensure that both
transmitter and receiver packs are at peak capacity.
Under normal conditions, subsequent recharging of your EXPERT system
will require only an overnight charge (approximately 16 hours) to
attainpeakchargecapacity.
The charger supplied with this system is designed to recharge your
transmitter and receiver battery packs at a rate of 50mAh.
The center pin of the charge receptacle on this radio system is Negative
polarity. Therefore, the center pin is negative, not positive. Your radio
system’s charge polarity is reversed from many other manufacturers
chargers. Beware of improper polarity connections based on “color
code” wire leads as they DO NOT APPLY in this instance.
You must always be certain that the center pin on any charger used
with this system is wired for negative polarity, otherwise damage will
occur to the charge circuit of the EXPERT. The Expert warranty does not
cover any system that is damaged by reverse polarity charging.

8. PRE-INSTALLATION SYSTEM PREPARATION
8.1
SL500 SERVO PREPARATION
Using a Phillips screwdriver, remove the servo arm retaining screws from each of the SL500 servos as shown in Figure 1.
Next, install 4 servo grommets and 4 servo eyelets to each SL500 servo as shown in Figure 2.

SYSTEM CHECK
Slide the power on/off switch on your EXPERT Transmitter to the
“on”position.
Next, slide the on/off switch on your flight pack switch harness to the
“on”position.
By moving each of the two transmitter sticks in a fore-aft, left-right
motion,thecorresponding throttle, rudder, elevator, and aileron
(optional) servo arm/wheel will rotate. Please refer to the transmitter
stickfunctionchartbelowforclarification.
With the system still activated (on), move the throttle stick to the
neutral (center) position. Double check to be sure that the four
transmitter trim levers are still in their neutral position.
Next, with the power still activated to the transmitter and flight pack,
remove the servo arm/horn from each of the SL500 servos, and then
turn the power “off” to the flight pack first, then the transmitter. By
doing this, the SL500 servos will be left in their neutral position, and
they are now ready to be installed into your model.
NOTE: Save the servo arms/horns; they will be reattached to the
servosafterinstallation.
