Model type selection (Type of model):
here you can choose the model type.
By selecting “Plane” you will be able to access the gyrosettings for surface models, as described in chapter 4.
The selection “Heli” will be made available through a future software update. It will enable a receiver-integrated
flybarless system, which can be adjusted inside the transmitters telemetry settings.
Low-voltage warning (ALARM VOLT):
if the receiver voltage falls below the set value, a low-voltage warning is
generated by the transmitter’s RF module in the form of the “general alarm tone”: a regular beeping at a rate of about
one per second; alternatively the speech output message “Receiver voltage”.
Temperature warning (ALARM TEMP):
if the receiver temperature exceeds the set temperature threshold, a warning
is generated by the transmitter’s RF module in the form of the “general alarm tone”: a regular beeping at a rate of
about one per second; alternatively the speech output message “Receiver temperature”.
Maximum altitude (Max. altitude):
at this point you can enter a maximum altitude, at which an alarm is triggered,
either via the transmitter’s RF module in the form of the “general alarm tone”: a regular beeping at a rate of about one
per second; alternatively the speech output message “Height”. Note: the model’s actual height is adopted as zero
when the receiver is switched on; the indicated height is therefore the altitude relative to the launch point.
Cycle time (PERIOD):
if your system is used exclusively with digital servos, you can set a cycle time (frame rate) of
10 ms at this point. If your system includes some or all analogue servos, you should always select 20 ms, as many
analogue servos cannot process the higher frame rate, and may respond by “jittering” or “growling”.
HoTT sum signal (SUMD):
if you activate the digital sum signal at channel 8, a sum signal containing eight channels
is present at this socket, instead of a servo signal. The HoTT receiver configured as SUMD constantly generates a
digital sum signal from 8 control signals from the transmitter and makes this signal available at the appropriate servo
socket, which is receiver-specific. At the time these instructions were revised, this type of signal is used by several of
the latest electronic developments in the area of flybarless systems, heavy-duty airborne power supplies, etc.
WARNING:
if you wish to use this facility, it is essential to observe the set-up information supplied with the
devices connected to the receiver, otherwise there is a risk that your model may be uncontrollable!

Telemetry sensor (sensor at K9): This jack allows you to use either for telemetry or for an extra channel (9). (Note:
Both together is not possible!) Switching is done in this menu item. If you select “Yes”, the socket is connected to the
connection of a sensor. If you select “No” a jack is connected to the control channel 9.
