Safety notes
!
These safety instructions are intended not only to protect the product, but also for your own and other people’s safety. Therefore please
read this section very carefully before using the product!.
• Do not leave the packaging material lying around, this could be a
dangerous toy for children.
• Persons, including children, with reduced physical, sensory or
mental capabilities, or lack of experience or knowledge, or not
capable to use safely the receiver must not use the receiver without supervision or instruction by a responsible person.
• Operation and use of radio-controlled models needs to be learnt!
If you have never driven such a model, then start extra carefully
and make sure to be familiar with the reactions of the model to
the remote control commands. Proceed responsibly.
7 / 16
33508_sh_V1
• First, always perform a range and function test on the ground (to
do so, hold your model tight), before you use your model. Repeat
the test with running motor and with short throttle bursts.
• Only use the components and spare parts that we recommend.
Always use matching, original Graupner plug-in connections of
the same design and material.
• Make sure that all of the plug-in connections are tight. When disconnecting the plug-in connections, do not pull the cables.
• Protect the receiver from dust, dirt, moisture and foreign parts.
It must be protected from vibration as well as excessive heat or
cold. The models may only be operated remotely in normal outside temperatures such as from -10°C to +55°C.
• Always use all your HoTT components only with the latest firmware version.
• If you have questions which cannot be answered by the operating manual, please contact us or another expert in the field.
For your safety by handling the transmitter and the receiver
!
WARNING
Also while programming the transmitter, make sure that a connected motor cannot accidentally start. Disconnect the fuel supply or drive battery beforehand.
!
CAUTION
Avoid every kind of short-circuit in all sockets of the transmitter!
Risk of fire! Use only the suitable connectors. In no case the electronic component of the transmitter or of the receiver 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 batteries
!
CAUTION
• Protect the batteries from dust, dirt, moisture, heat and vibrations. Only use in dry locations.
• Do not use any damaged battery.
• Batteries may not be heated, burned, short-circuited.
• If handled improperly, there is a danger of fire, explosion, irritation and burns.
• Leaked electrolyte is caustic and should not be touched or
come into contact with your eyes. In case of emergency, rinse
with a large quantity of water and consult a Med. Doctor.
• Stock the batteries in dry and fresh conditions.
• Dispose of the battery in the proper disposal centers.
Installation
The receiver must be protected against dust, exhaust gases, splash
water, etc. in the model. When you install your receiver, make sure
that it is not excessively airtight to prevent it from overheating during
operation.
Servo cables may not be wound around antennas or run next to
them. Make sure that the cables cannot shift to lie directly adjacent
to antennas during flight.
In the case of carbon fibre fuselage, at least the last 35 mm of the
antennas shall be routed from the fuselage.
Connections
Connect the devices that have to be connected to the receiver to the
row of sockets on one end of the receiver. The servo connections of
the Graupner-HoTT receiver are numbered.
The polarity of the plug-in system cannot be reversed. Do not apply
force.
Power supply
For the battery connection are designated the ports 1 and 6, they
are also provided with an additional "B". In principle, however, you
can connect a battery to any free socket. By V- or Y-cable, but also
with any remote control component. We recommend that you connect the power supply to the socket(s) close to the servos already
connected to the receiver. If you wish to connect multiple separate
batteries, the batteries must be of the same nominal voltage and
capacity.
9 / 16
33508_sh_V1
Never connect different battery types or batteries with strongly different charges since this can cause an effect similar to a short circuit.
In such cases for safety reasons, insert voltage stabilizing elements
such as PRX-5A (No. 4136) receiver power supplies between the batteries and receiver.
Attention
When selecting and connecting a power supply, be aware that
although the operating range of the receiver ranges from 3.6 to 8.4
V. However, practically all of the previously marketed servos, speed
controllers, gyros, etc. as well as many which are offered today have
a permissible operating voltage range of 4.8 to 6 V.
binding
To establish a connection with the transmitter, the Graupner HoTT
receiver must first be "bound" to at least one model memory in "its"
Graupner HoTT transmitter. This process is generally called "binding".
Binding step by step
1. Prepare the transmitter to be bound according to its instructions
for binding.
2. Switch the receiver power supply on.
The LED of the GR-16 HoTT receiver blinks in red with a slow
rhythm.
3. Push and hold for about three seconds the SET button on the
receiver.
After this time has elapsed, the LED flashes red and green simultaneously for a further approx. three seconds. During this time,
the receiver is in bind mode.
4. Start the transmitter-side binding according to the instructions
of the transmitter.
5. If the LED of the receiver starts to light constantly green within
approximately three seconds, the binding process has been completed successfully.
Your transmitter/receiver combination is ready for operation.
If the LED flashes slowly red, the "binding" has failed. Change the
positions of the associated antennas and try the entire procedure again.
Display and adjusting the receiver settings
The settings of the receiver can be displayed with a suitable HoTT
transmitter or the SMART-BOX and some can also be changed. Refer
to the "Telemetry" section for detailed descriptions.

Depending on the settings in the "6CH FUNCTION" line of the "RX

to connect RC components or a circuit for voltage measurement.
Carry out the changeover as described in the instructions for the
transmitter or the SMART-BOX.
• SERVO
The connection 6 is suitable for the operation of RC components.
• BATT V
After switching as described before, a DC voltage off max. 25,5 V
can be displayed instead of the receiver voltage. This way it is
possible to monitor the main battery voltage without using external sensors. The ESCs S3082 and S3083 have this switch already
included.

Firmware update
Updates to the receiver’s firmware are made via the receiver connection 5 using a PC running Windows 7 ... 10. You will also need a
USB interface, order no. 7168.6, and adapter lead, order no. 7168.6A
or 7168.S, which are available separately.
The programs and files required can be found in the Download area
for the corresponding products at www.graupner.de.
Connect the adapter lead to the USB interface. The polarity of the
plug-in system cannot be reversed. Note the small chamfers on the
sides. Do not use force, the plug should click into place easily.
Connect the other end of the adapter lead to the receiver's socket
labelled with "- + T". The polarity of the plug-in system cannot be
reversed. Do not apply force. The plug should be fully inserted.
The update is carried out via the "HoTT device" program section of
the program "Firmware_Upgrade_gr_Studio". Please follow the
notes of the software. The further procedure is also described in
detail in the manual contained in the data package. You can also
download these from the download page of the product at
www.graupner.de.
Differences of the offered firmware versions
• The version "FS_gr_rx8…" uses the original SUMD protocol with
Fail-Safe-Bit = 1 in case of Failsafe.
• The version "gr_rx8…" uses a SUMD protocol with Fail-Safe-Bit =
0 in case of Fail-Safe.
Some flybarless systems can only use this protocol. In this case,
the correct effect in the case of fail-safe must also be set in the
flybarless system and checked with disassembled blades.
