1. Introduction Dear Customer, thank you for purchasing this product. This product complies with the statutory national and European requirements. To maintain this status and to ensure safe operation, you as the user must observe these operating instructions! These operating instructions are part of this product. They contain important notes on commissioning and handling. Also consider this if you pass on the product to any third parties.
3. Intended Use The 4-channel remote control „HT-4“ is solely designed for private use in the field of model construction and the operating times associated with it. This system is not suitable for industrial use, such as controlling machines or equipment. Any use other than that described above can damage the product and involves additional risks such as short circuit, fire, electric shock, etc.
6. Safety Information The guarantee/warranty will expire if damage is incurred resulting from non-compliance with these operating instructions. We do not assume any liability for consequential damage! We do not assume any liability for property damage and personal injury caused by improper use or non-compliance with the safety instructions! In such cases the warranty/guarantee is voided.
• When you operate the model, always make sure that no parts of your body, other people or objects come within the dangerous range of the motors or any other rotating drive parts. • Improper operation can cause serious damage to people and property! Always make sure that the model is in your line of sight and do not operate it at night. • Only operate your model if your ability to respond is unrestricted. Fatigue or the influence of alcohol or medication can lead to wrong responses.
. Notes on Batteries and Rechargeable Batteries • Keep batteries/rechargeable batteries out of the reach of children. • Do not leave any batteries/rechargeable batteries lying around openly. There is a risk of batteries being swallowed by children or pets. If swallowed, consult a doctor immediately! • Batteries/rechargeable batteries must never be short-circuited, disassembled or thrown into fire.

10. Setting up the Transmitter In the further course of these instructions, figures in the text always refer to the adjacent figure or the figures within the section. References to other figures are indicated with the corresponding figure number. a) Inserting the Batteries For the power supply of the transmitter you will need 4 alkaline batteries (e.g. Conrad item no. 652507, pack of 4, order 1) of the size AA/mignon.
c) Setting the Control Lever Length You can adjust the length of the control sticks, depending on your steering habits. To do so simply hold the bottom part of the grip (1) and turn the upper part (2) up anti-clockwise. You can now set the length of the control stick by turning the bottom part of the grip. Finally, tighten the upper part of the grip back up. Figure 4 11.
The connections are designed for JR plug connectors. If required, Futaba plugs can be used as well, if a key file or a sharp knife is used to remove the narrow guide bridge at the plug. When connecting servos and speed controllers, always make sure of correct polarity of the plug connectors. The plugin connection for the positive lead (yellow, white or orange, depending on the manufacturer) must be connected to the inner (left) pin contact.
. Installing the Servos The installation of a servo (1) always depends on the particular model used. Detailed information on this can be found in the construction documents of the model. Generally, however, try screwing in the servos in a vibrationdampened manner. This is why rubber bushings (2) with metal sleeves (3) are usually included with the servos. Figure 7 When servos are obstructed, the servos cannot assume the required positions.
. Setting the Trim The trim mostly serves to correct the slight inclination of the servo levers due to the interlock and the connected irregular control movements. Additionally, there is the option to adjust the model in operation precisely, e.g. if it is not flying straight although the control lever is in the middle position. Then the linkage or rudder rods must be adjusted so that the trim has its original value (90°-range between servo lever and linkage) again and the model still runs straight.
. Checking the Servo Directions of Travel Connect the servos inserted in the model to the receiver. Pay attention to the assignment of the receiver outputs as described above. If your model has two aileron servos, there is the possibility of operating both servos with a V-cable at the receiver output „CH1“. Take the transmitter into operation, then the receiver.

15. Switching the Servo Directions of Travel If the rudder movements are not according to figure 10, you can switch the running direction of every single servo with the reverse switches (also see figure 1, item 8). The switches are assigned as follows: „AIL“ = Aileron/roll servo „ELE“ = Elevator servo „THR“ = Throttle servo/flight controller „RUD“ = Rudder/tail servo If the switch is in the bottom position, the „regular“ running direction is set.
16. Changing the Control Stick Allocation If you want to control your flight model according to the chart shown in figure 10 (mode II), you an skip this section. If you prefer the throttle function on the right control lever and the elevator function on the left one (Mode I), you may convert the transmitter accordingly. To make the necessary changes, some experience with remote control transmitters is required.
17. Delta Mixer The remote control „HT-4“ has a delta mixer that can be activated with the mixer switch (also see figure 1, item 9). When the slider is in the bottom position, regular operation without mixer function is active. When the slider is put up, the delta mixer is activated. For a delta plane model with triangular wing, the ailerons also have to perform the elevator function. For this reason, the channels „CH1“ (aileron) and „CH2“ (elevator) are mixed in the delta mixer.
18. Switching the Digital Code The remote control transmitter enables you to control receivers with the digital code „AFHDS“ and „AFHDS2A“. Ex works, the transmitter is set to the enclosed „AFHDS2A“-encoded receiver. If you want to operate a REELY receiver with the digital code „AFHDS“, the transmitter must be switched first and then the receiver must be bound to the transmitter (see following chapter). To switch the digital code at the transmitter, proceed as follows: • Switch off the transmitter.
19. Binding Function To enable transmitter and receiver to work together, they must be bound by the same digital code. In the delivery state, transmitter and receiver are aligned with each other and can be used at once. The binding settings must be renewed mainly after a replacement of the transmitter or receiver or to remove any interferences. Before you can bind the receiver to the transmitter, check if the transmitter works in the right digital code (see previous chapter).
20. Simulator/Student Transmitter Function If required, you can also use the transmitter at the PC for simulations or games. In this case, you will require the optional USB cable (Conrad item no. 517956) and suitable computer software (e.g. flight simulation games, etc). The USB cable is connected to the PS/2 interface socket (16) at the rear of the transmitter. At correct connection and proper installation, the activated transmitter is recognised by the operating system (e.g.
23. Disposal a) General Information The product does not belong in the household waste! At the end of its service life, dispose of the product according to the relevant statutory regulations. Remove any inserted batteries or rechargeable batteries and dispose of them separately from the product. b) Batteries and Rechargeable Batteries You as the end user are required by law (Battery Ordinance) to return all used batteries/rechargeable batteries.
24. Troubleshooting Even though the remote control system was built to the state of the art, there can still be interference or faults. For this reason, we would like to give you some information on how to deal with possible problems. Problem Remedy Transmitter doesn’t respond • Check the batteries in the transmitter. • Check the polarity of the batteries. • Check the battery contacts of the remote control. • Check the on/off switch. The servos do not respond • Check the batteries in the receiver.
