NOMENCLATURE

Slide UP to turn ON the transmitter
Adjust the proportion of throttle signal on either side of the centre trigger position.
Use the proportion of Forward/Reverse you prefer. We recommend using the 7:3 position for most applications.
ST.REV (Steering Reverse) :This function reverses the
rotation direction of the STEERING servo.
TH.REV (Steering Reverse) :This function reverses the
rotation direction of the THROTTLE servo.
STERRING DUAL RATE :Use this function to adjust the
steering travel of your model. If the model understeers
while cornering, add steering by turning CW of the D/R
button. When the model oversteers, take away steering by
turning CCW of the D/R button.

STERRING TRIM :The trim is used to adjust the steering
setting so that the car moves in a straight line without
using the steering wheel to compensate.
Please note! : The neutral and maximum positions are indicated by a long beep tone.
Install the Receiver in your model using double-sided Velcro. Velcro will hold the receiver in place and protect it from
vibrations. Mount the antenna up and away from the vehicle in an antenna tube. The higher up the antenna is, the better
signal it will receive.
Install and connect the receiver, servos and other components in accordance with the “Assembly Precautions”.
CAUTION: NEVER CUT THE ANTENNA
THROTTLE TRIM :The trim is used to adjust the setting
of the neutral position of the throttle without using the
throttle/brake trigger to compensate.
Remove the cover and insert 4 AA size batteries.
Observe the polarity markings and insert accordingly.

LINK/BIND Button
Each transmitter has an individually assigned, unique ID code. In order to start operation, the receiver must be linked with
the ID code of the transmitter with which it is being paired. Once the link is made, the ID code is stored in the receiver and
no further linking is necessary unless the receiver needs to be used with another Varioprop S2R transmitter.
LINKING/BINDING PROCEDURE:
1. Turn On the Transmitter with pressing on the receiver button for 5 seconds
2. The red LED is flashing slow
3. Power On the receiver
4. The red receiver LED is flashing slow
5. Press the receiver button
6. The linking is finished once the receiver LED stop flashing
Please note! The transmitter stops the linking procedure after the third double beep signal.
The S2R comes with failsafe set to neutral position on steering and throttle channel. In the event of loss of signal the motor
will stop and the vehicle will drift. If the signal is regained normal function will return.
If you wish to program the failsafe to a custom setting just follow these simple steps:
1. With both the transmitter and receiver powered ON, press the receiver button on the receiver for about 3 seconds.
2. The receiver will enter the failsafe setting menu and the receiver LED will flash.
3. You have about 3 seconds to move the transmitter controls (steering and throttle at the same time) to the position that
you wish to program into failsafe.
4. After the 3 seconds the receiver will save the settings and return to normal mode.
5. If you wish to reset to a different setting, simply repeat the above steps.
Please note! We recommend to let the failsafe in the neutral position for use in electric powered cars and boats.

LINKING THE RECEIVER AND TRANSMITTER
FAILSAFE SETTING

The EPA supports precise and individual endpoint adjustment in each direction for the steering and throttle channels.
1. Hold the throttle trigger in the full brake position while powering on the transmitter
2. The red LED flashes rapidly, indicating the programming mode is active.
3. Throttle End Point adjustment: Hold the trigger in the full throttle position and increase or reduce the travel with the TH
Trim button.
4. Brake End Point adjustment: Hold the trigger in the full brake position and increase or reduce the travel with the TH Trim
button.
5. Left Steering End Point adjustment: Hold the steering wheel in the full left position and increase or reduce the travel
with the ST Trim button.
6. Right Steering End Point adjustment: Hold the steering wheel in the full right position and increase or reduce the travel
with the ST Trim button.
7. Power Off the transmitter to save the new EPA settings.
Please note! The transmitter stops the linking procedure after the third double beep signal.
1. Gently pull the trigger to move your model forward.
The speed is proportional, the more you pull the trigger, the faster the model moves forward.
2. Release the trigger in neutral position to slow down your model.
3. Pull the trigger forward to brake your model.
For reverse, after stopping the model, release the trigger to neutral position then pull the trigger forward again to
activate reverse.
Gently rotate the steering wheel clockwise/counter-clockwise to turn the
wheels. The steering is proportional, the more you turn the wheel, the more the
wheels will turn.

CHANGING THE TRAVEL ADJUST SETTINGS (EPA)
OPERATE YOUR MODEL

Check the receiver, servos, and battery connectors, to be sure they are firmly connected. If a connector is not fully
inserted, vibration may cause the connector to work loose while the model is operating. This will result in loss of
control.
Operate each servo horn over its full stroke and check to see that the linkage does not bind or is not too loose.
Excessive force applied to the servo horn by binding or poor installation may lead to servo problems and result in loss
of control.
Electric Cars and Boats : Isolate the receiver from vibration by attaching to the chassis or mounting plate with thick
double sided tape.
Gas Powered Cars and Boats : Isolate the receiver from vibration by wrapping it in foam rubber or similar type cush-
ioning material. Protect the unit from water damage by placing it in a plastic bag or waterproof radio box.
The receiver contains precision electronic parts. These parts are vulnerable to vibration and shock. Any contact with
moisture (water or condensation) may cause receiver malfunction and loss of control.
Keep all devices that emit high frequency noise, such as motors, batteries, and wiring that handles heavy current
loads, at least 1/2 inch away from the receiver and the receiver antenna. High frequency noise will cause a decrease
in operating range and could cause loss of control.
Install electronic speed control heat sinks as well as other components that conduct electricity so they can not come
in contact with aluminium, carbon fibre or other materials that conduct electricity.
If, for example, the speed control came loose while the model was running and touched an aluminium chassis, a
short circuit may occur that would cause irreparable damage to the system as well as loss of control.
Noise suppression capacitors should be installed on almost all motors. If the proper capacitors are not installed, high
frequency noise will reduce range and cause loss of control along with various other problems.
Inspect all linkage installations and any point where metal could come in contact with other metal parts. Make sure
these parts do not touch other metal parts under vibration. Should a linkage or other metal parts come in contact
with other metal parts under vibration, the high frequency noise generated by this contact will cause interference and
possible loss of control.
Do Not disassemble any part of this system that is not specified in the instruction manual. Varioprop will not be
responsible for any damage due to improper disassembly of any part of the radio control system.
The user is cautioned that changes or modifications not expressly approved by the party responsible for compliance could
void the user’s authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15
of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in ac-
cordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee
that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the
equipment OFF and ON, the user is encouraged to try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer.
