9. Using the remote control The numbers used in these instructions refer to the illustration alongside the text or the illustrations within the respective section. Cross-references to other figures are indicated with the corresponding number. a) Inserting batteries into transmitter Four AA/mignon batteries are required to power the transmitter (we recommend high-quality alkaline batteries).
10. Basic functions of the transmitter a) Selecting colour of LEDs or turning LEDs off The colour for the LEDs (16) of the battery/rechargeable battery status indicator is adjustable, and these can also be turned off. Proceed as follows: • Switch on the remote control. • Press and hold down the "BACK" button (13) and turn the knob (14) to the left or right until the desired colour (you can select green, blue, cyan, red, yellow and white) is set for the LEDs or until they are disabled.
• If you press the knob (14) briefly, the "STK.CAL." indication will stop flashing. • The transmitter is ready for operation again. If one of the end positions has not been saved correctly, you will not be able to exit the calibration mode; the transmitter will vibrate briefly (similar to the vibration alarm of a smartphone) and emit a warning beep. Then proceed as described above and bring the steering wheel (4) and the throttle/brake lever (6) into their respective end positions.
e) Pairing the receiver with the transmitter (binding function) The manufacturer has already paired the included receiver with the transmitter. However, if you would like to pair another receiver or if you have reset the transmitter to factory settings, the receiver must first be paired with the transmitter (also known as "binding") before it can respond to the transmitter's control commands. Proceed as follows: • Disconnect the receiver from the voltage/power supply. Switch off the remote control.
11. Receiver a) Connection The receiver (C) can be connected to up to 6 servos (A), CH1 – CH6 connections, as well as a receiver power supply (B) and "BIND" port. The connections are designed for polarity-proof Futaba connectors and can also be used with JR connectors, if necessary. In the top right example, 6 servos (A) are connected to the receiver (CH1 – CH6 connections). In this case, the "BIND" port (19) must be connected to the voltage/ power supply (B) in the form of a battery box.
b) Installation The installation of the receiver depends on the model. For this reason, you should always follow the recommendations of the model manufacturer regarding receiver installation. If you want to use the integrated gyro sensor iin the receiver (SVC function of the transmitter will be enabled), the receiver must be mounted horizontally (max. 10° deviation from the horizontal plane). The receiver connections must point upwards vertically.
d) Calibrating the gyro sensor The receiver has a built-in gyro sensor. It can be used to automatically counter-steer (SVC function of the transmitter) a car model in case the rear is swerving (oversteer). The gyro sensor is already factory-calibrated; however, you can also calibrate it yourself. Proceed as follows: • Switch off the transmitter (it must not be switched on during calibration of the gyro sensor).
12. Installing the Servos The installation of a servo (A) always depends on the model used. For specific information, refer to the design documents of the model. However, generally you should try to fasten the servos with screws in such a way that vibrations are minimised. For this purpose, servos are usually provided with rubber grommets (B) with metal sleeves (C). In case of stiff linkages, servos can not run in the required position.
13. Transmitter setup menu a) General information After switching on the transmitter (see chapter 9. b), the transmitter will emit a beep, the display indication will appear and the display backlight will be enabled. The display backlight will automatically go out in a few seconds if the knob or the "BACK" or "BIND" buttons are not pressed.
c) "MODEL" function: Selecting model memory The transmitter has a total of 20 model memories (01 – 20). This provides the opportunity to operate up to 20 car models. Please note that a receiver can only be paired with one model memory at a time. If you have several vehicles, each with its own built-in receiver, first select a model memory and then pair the receiver with the transmitter. Proceed in the same way for all other models/receivers.
d) "NAME" function: changing the model memory name A 4-digit name can be entered for each of the 20 model memories. The letters A – Z and the numbers 0 – 9 are available. Proceed as follows: • If you have not already done so, first select the desired model memory; see chapter 13. c). • If you press the knob (14) briefly, the MODEL function will be greyed out. • Turn the knob (14) to the left or right until the NAME function is greyed out, as shown in the right figure.
e) "REV" function: reverse setting It may be necessary to change the direction of rotation of a servo or to reverse the reaction of the speed controller depending on the model installation position and linkage. The reverse setting can be made separately for each of the 6 channels of the transmitter. Proceed as follows: • If you press the knob (14) briefly, the MODEL function will be greyed out. • Turn the knob (14) to the left or right until the REV function is greyed out, as shown in the right figure.
f) "EPA" function: setting the maximum servo deflection This function can be used to determine the maximum permissible deflection for the steering, throttle or auxiliary servo on each side (EPA = "end point adjustment"). This feature is typically used to protect the mechanical system of a fully deflected servo from hitting an obstacle mechanically. You can set a value from 0% to 120%. The smaller the value, the shorter the servo way on the corresponding side.
• Turn the knob (14) to the left or right to adjust the servo deflection in the range of 0% to 120%, as shown in the top right figure. • If you press the knob (14) briefly, the setting value for the servo deflection will stop flashing. The current setting is saved. If you want to set the servo deflection in the other direction (or for another channel), start over (briefly press the knob, then select a channel, etc.).
g) "SUB-TR" function: adjusting the servo centre When installing the servos, the model manufacturer usually describes the exact central position for the servo levers. However, the cogs on the servo lever may not always allow the exact positioning of the servo lever if the operating levers and the corresponding trim are in the central positionon the transmitter. In this case, the trimming would not be centred when driving straight ahead.
h) "D/R" function: dual rate setting You can use this function to set the servo travel for channel 1 (steering servo) and channel 2 (throttle/brake servo or speed controller). For example, it can be used to limit the maximum steering angle, which makes it easier to steer the vehicle when driving faster, as it reacts more sensitively. The function can also be used to limit the maximum speed of a vehicle for a beginner.
i) "EXP" function: exponential setting You can use the exponential setting to change the linear pairing between the control transmitter and the servo travel in the middle position range. The maximum possible servo deflection (servo end positions) is not limited by the setting of the exponential function. The servo travels may be stronger or weaker in the middle position range depending on the value set. For "0" setting, servo travel is linear.
j) "ABS" function: ABS brakes With the ABS function, you can optimise the braking behaviour of your model car. The brake function is clocked electronically to prevent blocking the wheels when braking in a curve. In a "real" car, special wheel sensors and electronics detect blocked wheels. Reduce the brake pressure on individual wheels so that a blocked wheel can rotate again. This is noticeable because of a pulsating brake pedal.
• If you press the knob (14) briefly, the relevant setting value will flash at the bottom right of the display. • To change the value, turn the knob (14). • If you press the knob (14) briefly, the indication will stop flashing. The current setting is saved. If desired, you can now select another function to be changed by turning the knob (14). To exit the setup menu instead, briefly press the "BACK" button (13).
k) "TRIM" function: Trimming In addition to the "SUB-TR" function for setting the servo middle position, the trimming function is used , for example, to set the straight-line stability of the vehicle. The trimming for channel 1 (steering) and channel 2 (throttle/brake servo or speed controller) can also be set with the rocker buttons (5 + 3) on the right-hand side of the transmitter. However, this trimming is only temporary and will be lost after switching the transmitter off and on again.
l) "F.SAFE" function: switching failsafe on/off As a special feature, the receiver has a failsafe function for all 6 channels. You can programme a specific servo position for each channel to be called up if the transmitter signal fails (for example, the throttle/brake servo runs at 100% brake in a car with an internal combustion engine). The programming takes place directly in the transmitter and is then transmitted to the receiver.
m) "CRAWL" function: Crawler mode Here you can set the steering mode for a crawler vehicle. This is for a vehicle built specifically for manoeuvring tests. For this purpose, crawler vehicles usually have steerable front and rear axles. The steering of the front and rear axles is controlled via a separate steering servo. This function enables you to switch between front axle steering, rear axle steering, reverse steering or co-steering of the two axles.
n) "SVC" function: gyro function The receiver has a built-in gyro sensor. It can be used to intervene in the steering or the throttle function (throttle/brake servo or speed controller) so that the vehicle does not oversteer. Proceed as follows: • If you press the knob (14) briefly, the MODEL function will be greyed out. • Turn the knob (14) to the left or right until the SVC function is greyed out, as shown in the right figure.
"Priority": oversteering the gyro function by steering movements When "Priority" flashes, briefly press the knob (14). You can now adjust the extent to which the gyro function will be affected by "desired" steering movements by turning the knob (14). Briefly press the knob (14) to confirm. The higher the setting value, the lower the effect of the gyro function on the actual steering movements with the steering wheel (4).
14. Checking the steering and driving functions a) Steering function Place the vehicle on a suitable surface so that all wheels can rotate freely and the vehicle is secure. Do not touch rotating or moving parts. There is a risk of injury! First switch on the transmitter and, if you have not already done so, set the trimming for the driving and steering functions in the middle position. Then turn on the voltage/power supply of the receiver.
b) Drive function If you pull the throttle/brake lever (6) all the way to the handle, the model should accelerate. If you push the throttle/ brake lever forward away from the handle, the model should brake or switch to reverse travel. If the drive of your model behaves exactly the opposite, then you can enable the reverse setting for the driving function.
15. Maintenance and cleaning This product does not require maintenance. Never disassemble it (except for the procedure for inserting the batteries into the transmitter described in these operating instructions). Clean the outside of the transmitter and receiver only with a soft, dry cloth or brush. Never use abrasive cleaning agents or chemical solutions, as these may damage the surface of the case. 16.
18. Troubleshooting Even though the remote control system was built to the latest available technology, malfunctions or faults might still occur. The following section shows you how to troubleshoot potential faults. Problem Solution The transmitter does not respond • Check the batteries in the transmitter and replace them with new ones, if necessary. • Check that the batteries are inserted correctly. • If you are using a two-cell LiPo rechargeable battery (rated voltage 7.
Vehicle does not steer • Check that the steering linkage is running smoothly. • Check the steering servo and steering linkage. It may be blocked by stones/ foliage or the like. • Check the connection of the steering servo (channel 1). • Check the dual rate setting of the transmitter (if the dual rate setting is too low, the servos will stop working). • Check the EPA setting of the transmitter. • Check the setting of the "CRAWL" function (it is only useful for crawler vehicles with all-wheel steering).
