■ Recharging NiCad Batteries
■ ■
The LYNX is equipped with an external charging jack so there is no need to remove the
battery pack from the transmitter. The Hitec CG-22 or 25A are made to charge these types
of batteries overnight or the approximately 12-15 hours. Please refer to the following
diagram, check to see that the charge light lights up after the connection is complete.

■ ■
■ Transmitter Antenna
■ ■
You must attach the transmitter antenna by screwing it into the hole located at the top left/
center of the transmitter. You may take the antenna out to store it. This storage area is
located on the backside of the transmitter. Always attach your antenna before use or you
will experience sever shortage of operating range that could result in damage to your vehicle
and or injuries to yourself and others.
4
■ ■
■ Changing X-tals
■ ■
Changing the x-tal to void conflicts with other vehicles is possible where permitted. (You must
check your local rules before doing so. For example, in the US, the FCC prohibits the changing
of transmitter x-tals on 72 and 75MHz). If you are eligible to change the x-tals, both the
transmitter and receiver x-tals must be changed together. You must change within the same
band, i.e. 75MHz to 75MHz, 27MHz to 27MHz, different bands can not be intermixed if your
radio is on 75MHz then 27MHz x-tals cannot be used. Use only Hitec x-tals when changing
frequencies.

2. Installation of Receiver and Servos
■ ■
■ Using separate power source for the receiver
■ ■
When using a separate power pack for the receiver instead of sharing the main power source,
please refer to the following diagram. After installation, turn on the power to the transmitter
first then turn the receiver on. (Always turn the transmitter ON first and OFF last.) This will
prevent the receiver from picking up stray signals and going out of control. Now, move the
controls to see if the servos are moving properly. If not, Check your wiring, battery charge or xtals if the servos do not move at all.

Electronic Speed Controls such as the Hitec HFX have a built in B.E.C. system inside the
speed control circuit. (Please verify whether your ESC has a built in B.E.C. circuit.) Plug
the receiver connector from the speed control into the “THROTTLE” or #2 channel on the
receiver, and the steering servo into the “STEERING” or #1 channel on the receiver. Now
you can connect the main power to the speed control and when the power switch is turned
on the speed control will regulate the power that the receivers can use.

remove the pinion gear from your car so that the wheels do not engage for this test).
✷ Check to see if either servos or speed control are working properly. If not check the
connections and make sure the main battery pack is charged.

Check to see if the servos are moving in the correct direction. If not, change the
position of the servo-reversing switch located on the top of the transmitter to achieve
the correct direction.
✷ If everything checks out then turn the receiver “OFF” first then the transmitter. (Always
remember; never have the receiver “ON” without the transmitter also being “ON”).

The most notable feature in the LYNX is the “Steering Rate Override (SRO) Switch”.
This feature allows you to override the dual rate and use from 40% - 100% steering travel
with one touch. Selectable via the screw adjustment on the face of the transmitter, this can
be used in situations where your dual rates are set so the car does not “Oversteer” on the
majority of the track but is set low to get around the hairpin. By pushing the “SRO” switch
as you approach the hairpin turn, you will get the preprogram amount of throw immediately
and be able to get around the turn faster. If you are stuck against the hose/board/wall/etc.
and don’t have enough steering throw to get you out, the “SRO” button on the LYNX can
get you out when other radios can’t. Experiment with this feature you will find it very
beneficial.

Dual rates for the steering servo can adjusted via the thumbscrew on the pistol grip. This
adjustment is critical for racers fine-tuning their cars handling “On the Fly”. The rate can
be selected from 40% - 100%. If your car is loose or “Oversteering”, dial the adjustment
back. If your car is pushing or “Understeering”, then dial the adjustment forward. This
adjustment is a must for setting up your car to perform at its best. Adjust the servo so at
100% of travel (the dial will be all the way forward), the servo does not bind. If the servo
binds, adjust the linkage to compensate. (Consult your vehicle’s instruction manual for
proper instructions on the linkage setup)

After verifying that the steering direction is correct, set the knob to the center. The servo
horn or arm should be a 90 degrees and the wheels should be straight. If not then make the
horn or arm 90 degrees by removing it and replacing it correctly. If the arm is at 90
degrees and the wheels are not straight, adjust the linkage to compensate. Once you have
these two settings correct, use the steering trim for fine-tuning. Note: Always trim your
car before you run or race. This is a common mistake made by beginners. If you have to
steer your car to go straight, you are fighting a loosing battle. Make sure it tracks straight
before you run it and driving will become much easier.

Adjust the servo link rod so that point “B” will arrive at the neutral position. When the
trigger is pulled to the maximum point, “C” should be as illustrated and at point “A” when
the trigger is pushed to the limit. Check to see if the vehicle moves forward when the
trigger is pulled. If the vehicle moves backwards the “Throttle” reversing switch will need
to be switched. If the model moves forward or reverse at the neutral position, use the
throttle servo trim to fine tune. If the servo moves the speed control farther than is needed
use the “EPA” adjustments to limit the travel to the proper distance.

is pulled and does when the trigger is pushed, check the motor connection first. If that
is correct then switch the throttle reversing switch to the opposite direction.
✷ Adjusting the full power position of the ESC (reversible version) is the same as the
forward only, except you must make sure you are adjusting the forward not the reverse.
If the trigger is pulled and the full power adjustment does not affect the speed but does
when the trigger is pushed, the servo reversing switch for the throttle needs to be changed
to the opposite direction. After this is determined, use the same 90% as discussed
previously for forward. Reverse on most speed controls is not adjustable.

Gas powered vehicles require the throttle servo to be set up to operate the carburetor and
brakes together. The EPAs are used in these cars to set the proper throw for the throttle
