ST24™ QUICK START GUIDE
FEATURES
Transmitter and Ground Station – All in One
The ST24 is not only an advanced 24-channel RC transmitter – it’s also a powerful Personal
Ground
Station (PGS) that includes built-in hardware and functionality for First-Person View
(FPV), a flight simulator and an Android™ tablet/pad. With the convenient and portable ST24 it’s
no longer necessary to use separate components to view and even record real-time video during
flight.
Improved Radio Diversity and Range
Dual 2.4GHz antennas are installed in the ST24 to improve radio transmission diversity
and
range. The result is a more reliable radio link with range that exceeds typical line of sight opera
-
tions.
Two-Way Communication With Telemetry
The ST24 not only transmits control information, it also downloads vital aircraft status informa
-
tion. During flight the pilot can see telemetry data including real-time battery voltage, signal
strength, aircraft altitude, airspeed, distance from home and more right on the screen.
Extended-Range Video Downlink
The built-in 5.8GHz video downlink makes it possible to view real-time video on the ST24’s 7”
LCD screen. And when used in conjunction with the Yuneec C-GO1 camera or other Flying Eyes
downlink transmitters, range can be up to 2,600 feet (800 meters) or more.
Universal Channel Control System
The Universal Channel Control System offers an innovative and revolutionary way to view,
set
and adjust every channel. From input devices and hardware to output channels and functions,
every setting and adjustment including reversing, dual rates, mixing and more is found in a single
menu. No longer do you need to struggle with cumbersome sub-menus or difficult to understand
abbreviations – the ST24 makes it easier to see and customize more channel settings than any
transmitter before.
Built-In Flight Simulator
You can use the built-in Android™ app based flight simulator to enjoy the convenience and bene
-
fit of learning or practicing to fly using the same transmitter and controls you’ll actually be flying
with.
Built-in Android™ Tablet/Pad
The built-in Android tablet/pad makes it possible to listen to music, watch videos, run apps
and
more. And when you’re connected to WiFi you can even check email, surf the web and upload
your latest photos and videos without the need for a separate device. This means you have more
functionality, flexibility and convenience packed into your very own Personal Ground Station
(PGS).
IMPORTANT NOTE:
This Quick Start Guide is NOT intended to replace the complete content
included in the ST24 instruction manual. Although the following information covers some of the
basic details you need to know we strongly recommend reading through the instruction manual
completely before charging/using the ST24.
CHARGING YOUR ST24
Use a suitable power source/supply (1.5A and 5V MAX output) and a cable with a Micro USB
connector to charge the 3.7V Li-Ion battery installed in the ST24. The time it takes to fully charge
the battery will depend on the current voltage/charge state of the battery and the charge rate of
your chosen power source/supply. For reference it will typically take approximately 6 hours to
charge a near fully discharged battery at the maximum recommended charge rate of 1.5 amps.
1. Connect the cable with the Micro USB connector to the suitable power source/supply
2. Connect the Micro USB connector to the corresponding port on the bottom of the ST24
3. When the transmitter is turned on the battery icon located in the upper right-hand corner of
the
screen (in select menus) will show a ‘plug’ inside while the battery is charging
You can also remove the battery from the back of the ST24 and charge it separately using
a
suitable Li-Ion battery charger and a lead with a compatible 2-pin JST connector (at a maximum
recommended charge rate of 1.5 amps).
IMPORTANT NOTE:
Charging the Li-Ion battery using an incompatible charger (such as a NiCd or
NiMH battery charger), or even a compatible battery charger with the incorrect settings, may
result in damage to the battery or even fire resulting in property damage and/or personal injury.
