3. FEATURES
2. FLYING SAFETY
Read the ENTIRE instruction manual to become familiar with the features of the
product before operating. Failure to operate the product correctly can result in
damage to the product, personal property and cause serious injury.
WARNING
Graupner HoTT receivers are compatible with all of Graupner transmitters and used to
airplane, helicopter and glider. HoTT system gives user real-time information on various
useful data such as user model’s RPM, voltage, temperature, user programmable warn
-
ing, and so on which are directly obtained from telemetric speed controllers equipped
with this HoTT system without having to install separate sensor devices. Of course, all of
those telemetric data can be also transmitted from separate sensor devices. The use of
up to 75 hopping channels provides advanced reliable operation while keeping from any
external interference.
All instructions, warranties and other collateral documents are subject to change at the
sole discretion of Graupner. For up-to-date product literature, visit http://www.openhob

1. Do not y your model near spectators, parking areas or any other area that could
result in injury to people or damage of property.
2. Ensure that all channels are working in the proper manner.
3. Perform a ground range check prior to the initial ight of the day
4. Do not y during adverse weather conditions. Poor visibility can cause disorientation
and loss of control of your aircraft. Strong winds can cause similar problems
5. We strongly recommend to set the Failsafe function and also recommend that the
preset Failsafe would be idle position
6. You need to set the function of the transmitter after removing a power battery from a
model or stopping a engine of a model.
7. Ensure that all your batteries have been properly charged prior to ight.
- The use of up to 75 channels ensures extreme operating reliability and immunity to
external interference.
- The broad reception voltage range of 3.6 V - 8.4 V (functional to 2.5 V) ensures full
func tionality even when voltage uctuates.
- Two LEDs signal operating status.
- The optimized sizes and weights
- Receiver input sensitivity and thus the range have been increased further.
- Servo connections in the front panel.

- SPECIFICATION
When switching on or adjusting the radio control system it is essential to keep the
transmitter antenna at least 30 cm away from the receiver antenna all the time. If
the transmitter antenna is too close to the receiver antenna, the receiver will be
overloaded and the status LED on the receiver blinks red. The transmitter
responds by repeating a single beep every second and the radio control system is
entered Fail-Safe mode. If the distance of the antennas between transmitter and
receiver would be simply longer than 30cm in this situation, the beep of transmit
-
ter is ceased and the status LED on the receiver turns solid green
1) Binding
- Switch on the transmitter and receiver. The status LED of the receiver blinks red until
the receiver is bound to the transmitter.
- Enter BIND mode of your specic transmitter and press & hold the SET button on the
receiver for over 3 sec, the red status LED and the green status LED blink together.
After that, follow the procedures of your specic transmitter to bind, the system will
connect within a few seconds. Once connected, the status LED on the receiver turns
solid green, indicating the receiver is bound to the transmitter. If the binding process
has failed, repeat the whole procedure.
- Binding a number of receivers in one model
It is possible to bind a number of receivers to a transmitter in one model. Every receiv-
er must be bound to the transmitter individually according to the procedure already
described.

- Mount the bound receiver in the target place in the model.
- Switch on the RC system so that you could observe the movement of the servos.
- Put the model on a at surface (pavement, closely mown grass or earth), and ensure
that the receiver antenna should be at least 15cm above from the ground.
- Face the model with the transmitter in your normal ying position, the antenna on
the transmitter shouldn’t be toward the model directly and it keeps stand horizontally
during range checking
- Enter range check mode of your specic transmitter and follow the procedures of your
specic transmitter to check the range. the transmitter repeat a single beep with a
regular rhythm, indicating the Range checking is processed normally.
- Walk over 50 meters away from the model with controlling the transmitter sticks
constantly and check whether the model is operating normally. You should have total
control of the model with the trainer switch pulled
- If control issues exist within 50 meters, the system should not be used. And contact
your local Service Department of SJ INCORPERATED.
- Range-check is automatically terminated in 90 seconds and it is also terminated by
turning off the range check function of your specic transmitter. the status LED on the
receiver turns solid green when terminated.
- Have your helper position the model and check effective radio range before every
ight while simulate all the servo movements which will take place when the model is
in ght. The ground range must always be at least 50m in order to ensure safe and
reliable model control.
The last bound receiver is the master receiver when the system would be in use. Every
telemetry sensors installed in the model must be connected to the master receiver,
since the only master receiver transmits sensor data through the downlink channel. The
second and all further receivers are operated as the slave mode which are connected
in parallel to the master, with the downlink channel switched off. The control signals can
be passed to a number of receivers simultaneously and also the different signal can be
assigned to each receiver through the Channel Mapping function of the transmitter or
the optional SMART BOX. The typical example would be the use of two servos for each
aileron, etc.
NOTICE : Make sure to double check that transmitter is bound to receiver by turning
off/on transmitter’s power after binging process is completed
2) Range checking
Before every ying session and especially with a new model, it is important to perform a
range check. All Graupner aircraft transmitters incorporate a range testing system which,
when activated, reduces the output power, allowing a range check. Notice that every
ying must not be permitted in the range checking mode and the model is restrained on
the ground. After binding the receiver to the transmitter, switch the on transmitter and
the receiver and wait until the status LED on the receiver turns solid red.

3. Fail-safe function
In its default state, the receiver is set to “Hold” mode. If you lose connection, all
channels hold last given command and the status LED on the receiver turn solid red.
The transmitter also repeats a single warning beep every second. You can use the fail
safe option by programming the throttle channel to respond to a fail-safe situation. : the
throttle channel of an engine-powered model should be set to idle, the throttle channel
of an electric-powered model to “stop”, and the throttle channel of a model helicopter to
“Hold”. When a signal is lost the throttle channel, all channels are driven to the failsafe
position so that it could prevent the model crashing and the personal injury or property
damage.
During normal operations (i. e. when controlling a model) never enter
the range check mode !
CAUTION
The two functions “Binding” and “Range check” described above can be
used by the programming button or the SMART-BOX without any inuence
on the setting value saved in the transmitter and the receiver. However, if
the fail safe option is used by the programming button, all the setting value
which is seen on the fail safe screen in SMART BOX, including the setting
value that could be installed by the programming button, might be reset. For
this reason, we recommend the programming by SMART BOX.
4. Range warning
Since the transmitter’s output is much higher than that of the receiver, the user tends
to be hard to notice the seriousness of the situation and try to keep full control of the
model. So when the receiver signal in the down-link channel becomes too weak, the
transmitter repeats a single warning beep every second. You should y back the model
towards the safe place until the warning signal ceases. If the beep warning does not
cease when you y back, it is that the transmitter or receiver low voltage warning or tem
perature warning is activated, you must land the model and cease operations without
delay in this situation.
