ST24™ QUICK START GUIDE
FEATURES
Transmier and Ground Staon – All in One
The ST24 is not only an advanced 24-channel RC transmier – it’s also a powerful Personal
Ground Staon (PGS) that includes built-in hardware and funconality 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-me 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-
ons.
Two-Way Communicaon With Telemetry
The ST24 not only transmits control informaon, it also downloads vital aircra status informa-
on. During flight the pilot can see telemetry data including real-me baery voltage, signal
strength, aircra altude, 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-me video on the ST24’s 7”
LCD screen. And when used in conjuncon with the Yuneec C-GO1 camera or other Flying Eyes
downlink transmiers, range can be up to 2,600 feet (800 meters) or more.
Universal Channel Control System
The Universal Channel Control System offers an innovave and revoluonary way to view, set
and adjust every channel. From input devices and hardware to output channels and funcons,
every seng 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
abbreviaons – the ST24 makes it easier to see and customize more channel sengs than any
transmier 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 praccing to fly using the same transmier 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
funconality, flexibility and convenience packed into your very own Personal Ground Staon
(PGS).
IMPORTANT NOTE: This Quick Start Guide is NOT intended to replace the complete content
included in the ST24 instrucon manual. Although the following informaon covers some of the
basic details you need to know we strongly recommend reading through the instrucon 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 baery installed in the ST24. The me it takes to fully charge
the baery will depend on the current voltage/charge state of the baery 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 baery 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 boom of the ST24
3. When the transmier is turned on the baery icon located in the upper right-hand corner of
the
screen (in select menus) will show a ‘plug’ inside while the baery is charging
You can also remove the baery from the back of the ST24 and charge it separately using a
suitable Li-Ion baery charger and a lead with a compable 2-pin JST connector (at a maximum
recommended charge rate of 1.5 amps).
IMPORTANT NOTE: Charging the Li-Ion baery using an incompable charger (such as a NiCd or
NiMH baery charger), or even a compable baery charger with the incorrect sengs, may
result in damage to the baery or even fire resulng in property damage and/or personal injury.
USING YOUR ST24
In the Radio Control (RC) Mode
For RC-only (non-FPV/camera-equipped) models
1. Power on the ST24 and enter RC mode
· Slide the Power Switch to the le to power on the ST24
NOTE: The switch does not extend beyond the surface of the transmier tominimize the risk
of accidentally powering the transmier off during use
Power Switch
·Tap the RC buon/icon
·Tap the Model Select buon/icon
· Select the type of model (Mul-copter, Airplane, etc.) you’d like to create or load
·Select an exisng model or create a New Model
·To create a new model tap the New Model buon/icon
· Give the new model a name, take or select an image (oponal), select a type (if applicable)
then Save the new model
2. Bind the ST24 to your receiver/model
· Follow the instrucons included with your receiver/model to enter the bind mode
· Tap the System Sengs buon/icon
· Tap the Refresh buon/icon
· Select the corresponding ID of the receiver/model
· Tap the Bind buon/icon
· The receiver/model should now be bound to the ST24. Or, if the receiver/model was not bound
successfully repeat the steps outlined above to complete the binding process.
3. Define the channels
·Return to the main RC Mode screen (tap the ’Back’ or ‘Home’ icons located near the boom of the
screen as needed)
· Tap the Channel Sengs buon/icon
