Technical Data Transmitter mc-28 HoTT Frequency band Modulation Transmitting power Control functions Temperature range Antenna Operating voltage Power consumption Range Dimensions Weight 2,4 … 2,4835 GHz FHSS 100 mW EIRP 16 functions of which 4 can be trimmed -10 … +55 °C Patch integrated in the case 3,4 … 4,35 V (1S LiPo) approx. 400 mA approx. up to 4.000 m approx. 235 x 228 x 66 mm approx.
Operation and use of radio-controlled models needs to be learned! If you have never operated a model of this type before, start carefully and make yourself familiar with the model's reactions to the remote control commands. Proceed always responsibly. Inform yourself before flying your model on which maximum altitude you can fly in the uncontrolled airspace over the starting position and do not exceed it.
! CAUTION Risk of fire! Avoid every kind of short-circuit in all sockets of the transmitter! Use only the suitable connectors. In no case the electronic component of the transmitter may be changed or modified. Due to licensing reasons, any reconstruction and/or modification of the product is prohibited. Note During transport protect the model and the transmitter from damages. For your safety by handling the battery ! CAUTION Protect all equipment from dust, dirt, moisture. Only use in dry locations.
The maximum charging current permitted may not be exceeded. Never leave the charger unattended when it is connected to the power supply. Batteries may only be charged in rooms fitted with smoke detector. Safety notes for stocking LiPo / LiIo batteries Batteries may only be stored in non completely discharged condition. Batteries may only be stored in dry rooms with an ambient temperature of +5°C to +25°C. Stock the LiIo/LiPo batteries with a cell voltage of about 3,8V.

Interfaces Provided connection Left provided connections 1- DSC socket 1 2 3 On the left side is located the DSC socket. This socket allows the trainer/pupil function and the use of flight simulators. For more information on the DSC socket and the trainer/pupil function see the section "DSC socket". 2- SD card slot The card slot is suitable for micro SD memory card. For information on removing and inserting the memory card, refer to the section "memory cards".
PC COM Port connection Through this socket it is also possible to connect the transmitter to a PC. The software that the computer needs as well as the appropriate USB driver can be found on the download page on www.graupner.de for the respective product. Mass storage memory If you select this option, then you can accede from your PC directly to the SD card (if insert). 2- Data socket The data socket is suitable for connection of an optional smart box or an external optional Bluetooth module.
Note Make sure that all the plugs are securely inserted in the respective sockets, and only use the provided plug-in connections with a 2-pin jack plug on the DSC side. In the "Transmitter setting" sub-menu, you can set one of the following modes in the "DSC output" line depending on the number of functions to be transmitted: PPM10, PPM16, PPM18 and PPM24. Default setting: PPM10.
The data writing on the memory card is remarked by the symbol of the "filling" of the memory card with black from left to right. After the installation of the memory card, there is a folder structure in it. These folders are actually empty. Finally, the log files are saved in sub-folders called "Modelname" named according to the structure 0001_year-month-day.bin. If a model memory is still nameless, the corresponding log files are saved in a sub-folder entitled "NoName".
Symbols in the display Telemetry symbols in the display The active model memory has not yet been bound to a receiver. Not flashing: RF transmitter function switched off.
Keys to the left of the display SET key 1. Briefly pushing the SET key will cause a jump from the displayed base screen to the multi-function menu. SET 2. In the settings menu activate (confirm) the settings fields by pressing the SET button. Selection keys 1.

Commissioning Hand pads Installing the hand pads The hand pads have to be installed on the sides of the transmitter. Hold the hand pad exactly upon the six holes and fix it with the 6 fixing screws. Use the same procedure for the other hand pad. Attention! Screw the fixing screws only with the hand pads on the transmitter case. The place inside the transmitter case will otherwise not be enough and you could damage the boards.
Anchorage for the transmitter belt On the upper side of the transmitter there is an eyelet which can be used to hook a neck-strap. Opening/closing the transmitter housing The transmitter should be opened only in the following cases: If a self centering stick has to be converted in non self centering If a non self centering stick has to be converted in self centering To set the control stick centering force Open step by step Before opening the housing switch the transmitter off.
General commissioning Throttle too high! ! Please select RF on/off? ON OFF Notice-safety query throttle position As soon as the transmitter is switched on then the throttle position is checked. If the throttle position is not in the motor-off area, then the drive motor may start in an uncontrolled manner. This check is performed by all the models with the setting "Motor at CH1 front/ back". The warning alarm "Throttle too high" appears. For this reason in this case the RF module will not be switched on.
Switch the transmitter off Power off Cancel If you push on the POWER button, by switched on transmitter, for more than 2 sec. a safety query appears (see image). Select the desired option with one of the pouch pads (up or down) and push the SET button. This safety query avoids an accidental switch off of the transmitter while in use. Binding The description of the binding process can be found in the Part 2 of the manual. To use a transmitter you must associate a receiver to the transmitter.
Charging the transmitter battery You have two charge possibilities: 1. Removing the battery from its case and charging it with a charger ! WARNING The charger should always be supervised during charge and it should be used only in rooms fitted with a smoke detector. Removing transmitter battery Remove the battery case cover. Then remove and disconnect the battery plug by carefully pulling on the supply cable. Charge the battery following the charger manual.
