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.

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.

There are two slots in the Sensor Station for RPM sensors. Any combination of optical or magnetic sensors can be used.
sensor with heli main gear / head speed ratios
Magnetic Sensor Installation
A. The magnetic sensor consists of two main parts, the sensor and magnet. Three small magnets are supplied with the unit.
B. The typical installation will have the sensor mounted on the motor mount or airframe, and one magnet attached to the
spinner backing plate or prop hub in such a way as to “trigger” a signal every time the rotating magnet passes in front of the
stationary sensor.
C. It is suggested a small hole be drilled in the spinner backing plate, or prop hub into which one of the magnets is set ush
using hobby CA.
D. Note the tolerances here are very tight, the distance between the sensor and spinning magnet need to be 1mm.
Each magnet has a X mark to identify polarity, please make sure the X mark to be faced out.
Note
Otherwise the sensor cannot detect the magnet.
