Introduction
Beginning with the Ver. 1.07 software Aurora transmitters will be fully capable of advanced 2.4G downlink data telemetry.
When using a combination of sensors and Hitecs micro “Sensor Station”, all of the following functions can be displayed on
the Aurora screen during the ight, and viewed on a PC in real time!
- On-Board Battery Voltage, (this is displayed without the use of sensors when the Auroras SPC function is used).
- Up to four dierent temperatures
- Measure RPM with either magnetic or optical encoders.
- Monitor liquid fuel usage
- Gather GPS data to see speed, altitude and location information
This installation guide will cover the physical installation of the Sensor Stations and sensors in airplanes and helicopters
including the related Aurora software screens and their features.
At the end of this manual is a description of how the HPP-22 PC interface can be used to display in real time, record and
play data collected during a ight.

1. Are You Updated?
One of the great features of the Aurora transmitter, Spectra 2.4 module and the Optima receivers is their ability to “be
up-dated” with new software. The HTS-SS sensor station now joins the product line with its software up-date capability.
To take advantage of the sensor telemetry we need to be sure your equipment has the latest software.
Step 1.
Does your Aurora have Software V 1.07 or greater? Check in the Aurora system menu – info menu screen, for your Aurora
software version. If not, You will need to update the Aurora software using the HPP-22 device.
Step 2.
Does your Spectra 2.4 module have Software V 2.00 or greater? If not, You will need to update the module software using
the HPP-22 device.
Step 3.
Does your Optima receiver have Software V 2.00 or greater? If not, You will need to update the Aurora software using the
HPP-22 device.
2. On-Board Battery Voltage
A key advantage to electric aircraft pilots is knowing the voltage of their on-board motor battery. This is done by using the
Auroras SPC function. When the SPC is connected, the motor battery voltage is shown on the Auroras home screen and in
the Cockpit mode.
Please note the SPC connection directions as found in the Aurora manual.
The voltage of your on-board battery can be viewed in real time on the Aurora’s screen three ways;
1. The rst is on the home screen.

3. The adjustable function on this screen is
the ability to set a Low Voltage Warning.
Depending on the number of cells used in
the on-board battery, use the +RST- icon to
set a low voltage warning point. It is not
good practice to allow each Lipo cell to fall
below 3 volts. That’s 6 volts for a 2 cell, 9
volts for 3 cell pack etc.
4. Note the MIN and MAX values of the
battery voltage shown on this screen.
5. The third way to view the battery voltage
is on the Cockpit screen.
The 3rd method is active even if the Sensor Station is NOT used.
Note
4. Temperature Sensor
The Temperature Sensors (HTS-TEMP) can measure temperatures from -40 to 392 degrees Fahrenheit(-40 to 200 degrees
Celsius). Up to four temp sensors can be used. These will most commonly be used in combination to read the temperatures
of the following model accessories;
Electric motor
ESC
Glow and Gas engine cylinder head
Battery
Muer
Voltage regulator
B.E.C.
Tailpipe
Ambient air
Installation
Installation will vary on the dierent applications. Note it is important to have the loop of
the sensor wire held tightly against the
device. Consider using zip ties, a piece of tape
and/or small dabs of silicone to hold the wire
in place.
Aurora transmitter interface
To access the temp screen menu the aircraft must be turned “on” and the temp sensors installed in the Sensor Station
properly attached to the receiver.
a. Access the System menu
3. Sensor Station
The on-board Sensor Station (HTS-SS) - collects all the data from each sensor, sending it back to your transmitter via the
Optima 7 or Optima 9 receivers.
Installation
Don’t install the Sensor Station right away. It
is best to t the sensors you will use into the
aircraft rst. Take the length of the sensor
wire leads into consideration before
permanently mounting. Then, install the
Sensor Station in your model using the
supplied double-sided tape.

b. Select “Sensor”
c. Press “TEMP”
The temp reading for any “unconnected” temp sensor will show -40.
Note
d. Press ▶ (arrow) to select between
F(Fahrenheit) and C (Celsius) readings.
