accurate. Depending on the type of ESC and the design of
the brushless motor, different pulse widths may be
produced for the same RPM. Hence the display does not
always give consistent results. Whether the RPM readout
is useful will depend on the ESC and motor you are using.4
Receiver and Flight Pack voltage
The telemetry unit is accurate to +/- 0.1v and the resolution
of the Spektrum™ transmitter display is limited to one
decimal place. Accordingly a true voltage of 13.00 V may legitimately
display as 12.9, 13.0 or 13.1 V. This resolution is adequate for tracking pack voltage during flight.
Either the internal or the external temperature sensor (if connected) will display on this screen. As
well, the RPM value will display if the sensor wire is connected to a motor wire.
Current and mAh used
The flight battery sensor is factory calibrated to the telemetry unit it ships with, but can be re-
initialized if used with another unit. Voltage limit is 30v and current 60 Amps. Again, the Hyperion
telemetry unit is within the resolution of the Spektrum™ display, which reads only in full Amps.
However, the pack voltage can be displayed to higher resolution on the “PowerBox™” screen of the
transmitter display, as well as the consumption from the flight battery in mAh. Hyperion claim better
than 5% accuracy in mAh consumption reporting, and in normal use, you can expect 2-3% accuracy.
This is quite good by hobby standards and is ample for tracking the state of discharge of the battery.
The PowerBox™ display will show Voltage and Capacity for only a single flight pack. Battery2 and
Capacity2 will always be zero.
Alarms
Alarms can be set in the transmitter telemetry setup screen for Min and Max values of Pack Voltage,
Current, RPM, Temperature, Altitude and Receiver voltage. Spektrum™ PowerBox™ and Flight Log
alarms are not applicable to the Hyperion unit. Alarms and
displays can be activated or inhibited. Alarms can be Tone,
Vibration or both.
Telemetry Range
While the Hyperion telemetry system peaks at 22dB. This
higher RF transmission power is intended to give better RF
transmission reliability. Practical tests by users have shown
that even with surrounding WiFi traffic a range of around
1000ft/300m is routinely achievable. Under better
conditions, about 1500ft/450m line of sight seems to be a
reasonable limit.
Advanced Adjustments
The unit has a small hidden rotating calibration pot that also acts as a 3-position switch. This
“pot/switch” is revealed by peeling back a corner of the label and is normally in the middle position. It
can be used to initialize a new current sensor, change the altitude display and calibrate the voltage
and current readings for maximum accuracy.
