b) Operation • If you do not have sufficient knowledge of how to operate remote-controlled models, contact an experienced model user or a model club. • When putting the device into operation always turn on the transmitter first. Only then turn on the voltage/ power supply for the receiver in the model. Otherwise, the model car can have unpredictable reactions. • Before using the model, check whether it responds properly to the remote control commands.
. Battery information • Keep batteries out of the reach of children. • Do not leave batteries lying around, as they present a choking hazard for children and pets. Seek immediate medical advice if a battery is swallowed. • Batteries/rechargeable batteries must never be short-circuited, taken apart or thrown into fire. This may cause an explosion! • When handling leaking or damaged batteries, always use suitable protective gloves to avoid burning your skin.
9. Remote control buttons The illustrations in this manual show the GT2 EVO remote control, which is identical to the GT2+1 EVO except for the switching function. This may cause labels or markings on your remote control to be different than depicted in this manual. However, the function notes described in the text refer exclusively to the GT2+1 EVO remote control.
If you open the control panel cover upwards, you have access to the other control elements of the transmitter.
. Using the transmitter 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 figure number. a) Inserting the batteries To power the transmitter, you need four alkaline batteries, size AA/Mignon. Proceed as follows to insert the batteries: The battery compartment lid (1) is located on the bottom of the transmitter.
b) Switching on the transmitter When the new batteries have been inserted, switch on the transmitter for testing purposes using the on/off switch (see also Figure 2, Pos. 10). To do this, move the control knob from the left (OFF) to the right (ON). The red LED for the operation control (see also Figure 2, Pos. 13) lights up and shows you the switched-on status of the transmitter. The green LED for the low voltage indicator (see also Figure 2, Pos.
11. Setting up the receiver a) Connecting the receiver The receiver allows you to connect three servos (receiver output CH1, CH2, CH3) and a receiver rechargeable battery (Bind/VCC). The connections are designed for polarity-proof Futaba connectors and can also be used with JR connectors, if necessary. When connecting servos and speed controllers, pay close attention to the correct polarity of the plug connectors.
* The servo for special functions at receiver output 3 is operated with the operating button for channel 3 (see Figure 2, Pos. 14). A switching module can also be connected instead of a servo. ** For an electronic model with an electronic speed controller, a separate receiver battery at the Bind/VCC connector is only required if the speed controller used does not have a BEC circuit. For further information, refer to the technical documents of the controller.
12. Installing the servos The installation of a servo (1) 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, the servos are usually enclosed in rubber grommets (2) with metal sleeves (3). Figure 8 In case of stiff linkages, servos cannot run in the required position.
13. Trimming the controls The trim serves primarily to correct a slight skew of the servo levers due to the linkage and the associated uneven control movements. In addition, you still have the opportunity to slightly adjust the model during operation, for example, when the drive is not straight although the steering wheel is in the central position. The steering arms should be adjusted so that there is a 90° angle between the servo lever and the steering arms.
14. Checking the steering and driving functions Now connect the servos or speed controllers used in your model and the power supply to the receiver. For a better understanding, the steering function is demonstrated using the example of a model car. To prevent the model from unintentionally starting when checking the control and driving functions, place the model with the chassis on a suitable base (wooden block or similar). The wheels should be able to turn freely.
If the wheels turn in exactly the opposite direction as shown in Figure 11, you can use the reverse switch for the steering function (15) to switch the effective direction of the steering wheel and thus the direction of rotation of the steering servo. It may then be necessary to set the steering trim again. Important! Figure 12 Set the linkage rods on your model so that the full steering deflection to the left and right is achieved without any mechanical impact or limitation on the steering.
b) Checking and setting the driving function If you pull the operating lever for the driving function (see Figure 1, Pos. 3) as far as it will go in the direction of the handle, the model should accelerate (see Figure 13, Sketch A). If the lever is pushed forwards, the model should brake or switch to reverse drive (see Figure 13, Sketch B).
15. Checking the switching function In addition to driving and steering functions, the GT 2+1 EVO remote control also offers the option of connecting and controlling a third servo on the receiver. If the operating button for channel 3 (also see Figure 2, Pos. 14) is pressed on the remote control, the output lever of the servo connected to the receiver output 3 runs from one end position to the other end position (see Figure 14 below).
16. Fail-safe function Your remote control receiver gives you the ability to put the throttle servo or electronic speed controller in a specific position or in the stop function if a correct remote control signal is no longer received in the event of a fault.
17. Switching the digital coding Your remote control transmitter provides the option of controlling receivers with AFHDS and AFHDS2A digital coding. The transmitter is factory-set to the enclosed AFHDS2A-coded receiver. If you want to operate a REELY receiver with AFHDS digital coding, the transmitter must first be changed over and then the receiver must be connected to the transmitter (see following chapter). To switch the digital coding on the transmitter, proceed as follows.
18. Pairing function For the sender and receiver to work together, they must be paired together with the same digital coding. When delivered, the transmitter and receiver are paired and can be used immediately. Renewing the pairing setting is required primarily after a change of transmitter or receiver or to correct for interference. Before pairing the receiver with the transmitter, check whether the transmitter works in the correct digital coding (see the previous chapter).
19. Simulator function If required, you can also use the transmitter on the PC for simulation purposes or games. In this case, you will need a USB interface cable and appropriate software for the computer (e.g., car racing games, etc.). The USB interface cable is connected to the PC interface socket on the left side of the transmitter (see Figure 1, Pos. 5).
22. 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 problems. Problem Solution The transmitter does not respond. • Check the transmitter batteries. • Check the polarity of the batteries. • Check the function switch. The servos do not react. • Check the receiver batteries or rechargeable batteries. • Test the switchgear cable.
