Non-electric Model
- When you install the system in an non-electric model (or mechanical type speed control), you
should use the battery holder to supply the power for receiver
E.S.C. Installation Model
Connection Precautions
A. Installation Note
- After you installed the system, please check the receiver, servo, and battery connections,
make sure all the connections are fully inserted.
- The package contains the rubber bungs, if the slot is not in using, it can be plugged with the
bung to prevent the water splashing.
- To protect absolutely the system from water or oil damage, you can place it in a plastic bag or
waterproof box.
- Please remember this; always turn your transmitter on first and off last. Failure to do so may
result in loss of control and can damage your servos and/or linkage.
B. Receiver Note
- Keep the receiver away from motor or engine when attaching to the chassis of car or boat.
- Keep the receiver away from the power wires to prevent the interference.
- Refer you model instructions, run the antenna up the antenna tube to gain the best receiving
effect.
- DO NOT cut off the excess antenna wire, or it will shorten the operation range.
- The receiver includes a BEC (Battery Eliminator Circuit) system, which eliminates the need
for an extra receiver battery when used with a mechanical or electronic speed control. The
battery power input should not exceed 8.4V
C. Servo Note
- After you installed the servos correctly, you will need to make sure they are properly centered.
To do this, remove the servo horns and turn on your transmitter, then the power to your
receiver.
- Power on the transmitter, check that the servos are working properly.
- You will now center the trim knobs on the transmitter and replace the horns so that they are
centered.
- Be aware they may not be perfectly centered; this is OK, just get them as close as possible.
Then use the trims for fine-tuning.
D. Battery Holder Note
- Please use the AA size of dry battery or Ni-Cad battery with the holder.
- Please connect the battery holder to external power switch first and then plug the power
switch into the “BAT” slot of the receiver.
- When you use a electronic speed control or mechanical speed control with BEC, you will not
need to connect the battery.
7. Transmitter Battery Installation
- Before you install the battery for transmitter, please check the transmitter power, keep it in off
position.
- Remove the cover and install the batteries as shown.
- Be careful to pay close attention to the polarity of each cell or the transmitter will not operate.
- Replace the cover back and make sure it is closed securely.
- About the battery status checking, please refer the part 8 “Transmitter Operation” to learn
about the power LED indicator.
8. Transmitter Operations
A. Antenna
- Please extend the antenna to the full length when you operating, to gain the best radio
performance.
- Be careful to handle the antenna, do not bend it.
B. Power Switch
- Stir the switch right to turn on the transmitter, and left to off it.
- Please note that turn on your transmitter first and then switch on the receiver switch to
prevent accidental runaways.
C. Power Indicator LEDs
- There are 3 LEDs to show the power status.
- Green is full power, amber is mid power and red is low power.
- When red LES is flashing, please replace the battery or charge immediately.
D. Steering Reversing Switch
- According to your model design, change the direction of the servo travel to fit the usage.
- The default position is “NOR”, if you steer right and the wheels go left, change the “ST.”
switch from “NOR” to “REV”.
E. Throttle Reversing Switch
- According to your model design, change the direction of the servo travel to fit the usage.
- You should not need to change the "THR" switch (default is “NOR”) when using an
Electronic Speed Control.
F. Steering Wheel
- Use the steering wheel to control the direction of your model.

G. Throttle Trigger
- Use the throttle trigger to control the throttle and braking for your model.
- Pull the trigger for throttle and push it for braking or reverse. (some of the ESCs support the
Reversing function)
H. Steering Trim
- Before you use the steering trim, you should center servo horn closer to the neutral position
with the linkage, and then use the trim to fine-tune the steering.
- Adjust the steering trim to make your model running perfectly straight when the steering
wheel is centered.
I. Throttle Trim
- Use the throttle trim to adjust the braking power; this is the amount of braking that occurs
when you let go of the trigger. Be aware that too much brake may affect the servo end point
preventing maximum power.
- When using a electronic speed control, you should keep the throttle trim in the center
position.
- Do not mount the horn on the servo until you turn on the radio and center the trims.
J. Steering Dual Rate
- Use the D/R function to adjust the overall travel of the steering servo.
- Push the D/R forward with your thumb for maximum steering and pull back for the minimum
steering.
K. Charger Jack
- When you use the rechargeable batteries (ex. Ni-Cad battery), you can insert the connector of
the charger into the jack to charge the batteries.
L. Battery Cover
- Remove the battery cover to change the batteries.
M. Crystal
- Replace the crystal to change the radio frequency.
- Do not use other brand’s crystal or the transmitter won’t work properly.
N. 2 / 3 Channel mode Switch
- Use this switch to change the transmitter to 2 or 3 Channel function.
- When the mode switch set in 2 channel mode, the multi-function switch will be set in “Dual
Rate Override” trigger.
- Or the mode switch set in 3 channel mode, the multi-function switch will be set in “3rd
channel” trigger.
- About the detail operations, please refer the “Multi-function Switch” section.
- Note: When you switch the 2/3 channel mode switch, please turn the transmitter power
off first, or the setting won’t be set in. After the switch settle down, and then turn the
transmitter power on.
O. Multi-function Switch
- According to 2/3 mode switch setting, the multi-function will be set in two different function.
2 Channel mode (Dual Rate Override)
Trigger off this function, the D/R value will be set in 120%. After shutting off, the D/R
value will become to the original setting.
3 Channel mode (3rd channel switch)
- Before use this function, you should plug the 3rd servo into receiver to enable the 3rd
channel function with your model.
- Trigger this switch on, the 3rd channel servo will swing from original position to another
side.
- According to mechanical design of the model, you may switch the 3rd channel trigger
from on to off for reversing the servo direction.

A. Troubleshooting
If your R/C system works abnormally, ex: remote range is short, transmitter malfunction, etc, please
check the table below to take the action to solve the problem, if it couldn’t solve the problem, and then
please contact your dealer to get the service.
Problem Check point Action
Batteries low Replace the batteries. Charge the
Ni-Cad batteries.
Crystal wrong, damage or
disconnected.
Please use the correct band crystal for
both transmitter and receiver. Check the
crystal connection; reinsert it into the
crystal holder tightly.
Remote range is short
Antenna disconnected.
Not extended to full length.
Screw it to the end.
Extend the antenna fully.
Servo is not running
smoothly
Receiver batteries low
Linkage binding or looseness
Replace the batteries.
Check and adjust the model.
Operation stops
intermittently
Wire disconnected.
Reinsert the connectors.
Push it tightly.
Model is glitch or
servo is running
erratically
There is another radio
operating on you channel.
The receiver antenna is near
the power wire.
Replace the crystal band.
Keep the antenna away from the power
wire.
B. User Tips
- Adjust the dual rate appropriately, it will make your
model passing the corner perfectly.
- Adjust the servo horn position and linkage so both are
parallel, it will make the servo action efficiency.
- Control your steering and throttle Nimbly, don’t push
the speed too much and overshoot when pass the
corner.
- Be careful to drive your model to prevent the crash.
Practice more on the conservative track to be familiar
with the operation, and then try the advance track.
- Have fun with your LG2-01!
