Safety notes
General
!
These safety instructions are intended to protect this product,
yourself and the safety of others. Please read this section very
carefully before using this product!
To avoid risk of suffocation, keep packaging materials away from
babies and small children.
Supervision by an experienced adult is required for chil-
dren, persons mentally or physically handicapped, nov-
ices, or anyone not capable of safely using this product.
Always perform a range and function test on the ground
before you use your model (hold your model tight). Repeat
the test with running motor and with short throttle bursts.
Check all relevant laws and regulations before using this
remote control model. These laws and regulations must
be observed in for the safety of yourself and others and
may vary by state, region, or country.
Special liability insurance policies are mandatory for all
device operations. If you already own a device, determine
if the respective model is covered by your insurance.

9 / 48
S1008_X-8E_jh_V1
Protect all equipment from dust, dirt, moisture, vibration and
excessive heat or cold. The models may only be operated
remotely in normal outside temperatures ranging from 14° to
130°F (-10°C to 55°C).
Maintain frequent updates of your HoTT components with
the latest firmware version.
For additional questions or support, contact the Graupner
USA Service Center, or an experienced user.
Battery Safety
CAUTION
Protect batteries from dust, moisture, heat and vibrations.
For use in dry locations only.
Do not use damaged batteries.
Batteries not handled properly may catch fire, explode, or
cause irritation and burns. To extinguish a battery fire use
either water, CO² or sand.
Batteries should not be heated, burned, short-circuited,
incorrectly inserted, modified, soldered or welded.
Charge batteries in a room outfitted with a smoke detec-
tor, on a non-flammable, heat-resistant and non-conduc-
tive surface. Keep away from combustible or highly flam-
mable objects while charging. Always monitor batteries
during the charging process.
Do not exceed the maximum quick-charging current
specified for the respective cell type.
If a battery reaches temperatures above 140°F (60°C)
while it is being charged, immediately stop charging and
let the battery cool down to approximately 86 - 104°F (30
- 40°C).
Never charge batteries that have already been charged,
are hot or are not fully discharged. If a cell in a battery pack
heats up following a quick-charge process, this may indi-
cate a defective cell. Discard the battery immediately!
!

10 / 48 S1008_X-8E_jh_V1
Damaged or corroded batteries may leak an electrolyte
that is caustic and should not be touched or come into
contact with your skin or eyes. In case of emergency,
rinse thoroughly with water and seek immediate
medical attention.
Always fully recharge the battery.
Special instructions on charging LiPo batteries
To charge and discharge LiPo batteries, only use specifi-
cally designed chargers/dischargers with balancer con-
nector.
The white connector (cell count + 1 pole) is designed for
the connection to a LiPo balancer or a battery charger as
a single cell charger with a manual cell balancer. Always
charge the battery with the balancer connector.
Safety notes for stocking LiPo batteries
LiPo batteries should be stored with a voltage of about
3.8V per cell. If the cell voltage falls below 3V, then the bat-
tery must be charged. Fully discharging or storing a bat-
tery with a cell voltage < 3V renders the battery useless.
Exersize safety procautions when charging and transport-
ing your LiPo batteries. Always use a safety bag.

Commissioning
Battery connection
Remove the cover from the bottom of the transmitter and con-
nect the battery, paying attention to the correct polarity. Shut
the cover and ensure it is securely closed.
Set the the battery warning threshold in accordance with the
battery used. (see Chapter “SYS SET”)
If a voltage warning is triggered, charge the batteries.
Battery charging
Charge the LiPo batteries in the transmitter through the micro
USB socket using the USB cable provided. For all other battery
types, use an USB connection, e.g. a PC USB port or an USB
net adapter. During the charging process the LED under the dis-
play lights up red. When the battery is full the LED turns off.
Alternatively, you can charge the battery outside the transmitter
with an RC battery charger (not included).
Transmitter power switch
On the top of the transmitter there are two buttons. To turn on
the transmitter with RF off, push the right button for about 2 sec-
onds. When the RF mode is off, a safety feature is activated that
prevents switched-on models from accidentally starting during
programming. Additionally, power consumption is reduced,
significantly conserving battery life.
To turn on the transmitter with RF on, push the left button.

RF SET
Binding and range test
Binding
To establish a communication link, bind the Graupner-HoTT
receiver to the X-8E Graupner-HoTT transmitter. The binding
process has already been performed for the transmitter and the
receiver included. However, binding is required for each addi-
tional receiver added to this transmitter. To bind additional
receivers:
NOTE: The transmitter can be turned ON or OFF with one of
two buttons. When using the white button, the transmitter RF
functions are completely disabled and it will not be possible
to turn on the RF or bind a receiver.
1. Turn on the transmitter using the RED button. If no
receiver is bound to the model, select SET. Selecting SET
will bring up the bind finction of the RF SET menu.
2. Select the correct RF system. (HoTT V2 for the GR-8 or
HoTT for the GR-4.) GR-8: The red LED flashes slowly
when there is no communications link. GR-4: The red
LED glows solid red when there is no communications
link.
3. Press and hold the SET button on the receiver for about
3 seconds.
4. Press the BIND button on the transmitter.
5. The OFF will change to CHK momentarily.
6. If the bind is successful, the number of receiver channels
will be displayed. If not successful, the button will return
to OFF status.
Repeat the bind process until successful. It is all a matter of tim-
ing. (Counting "one thousand one, one thousand two, one
thousand three" will help with the timing.)

Range test
Always perform a range test before each operation. Have an
assistant to help with the range test. Range test instructions are
as follows:
1. Bind the receiver with the transmitter and insert into the
model. Switch on the transmitter first, then the receiver.
Servo movements can now be monitored.
2. Place the model on a flat surface (cement, mowed lawn
or level ground) with the receiver antennas at least 6 in (15
cm) above the ground. If necessary, place a support
underneath the model during the test. Hold the transmit-
ter at waist-level at a comfortable distance from your
body. Do not point the aerial directly at the model.
Turn or angle the aerial tip so it stands vertical during oper-
ation. In the “RF SET” menu, press OFF in the “RANGE
TEST” line. This switches the option ON and begins the
range test. The test will ramian active for 99 seconds,
after which it will automatically switch off. (Quit the range
test at any time by pressing ON in the “RANGE TEST” line
to switch this option OFF.)
3. Walk away from the model and turn the wheel to simulate
all servo movements and normal operations. If at any time
you detect an interruption in the link within a range of
about 164 ft (50 m), attempt to reastablish the link.
4. To check interference resistance, switch on an existing
motor. Move away from the model until it no longer
responds. Manually terminate the range test mode.
5. The model should now respond again. If not, do not use
the system and contact the Graupner Service Center.
6. Ground range for safe operation and handling should be
within 164 ft (50 m).
