FrSky Advanced Engine Suite
Advanced Engine Suite (AES) is a multi-functional management box suitable for application in airplanes equipped with engines.
The AES module is equipped with a wealth of sensor interfaces, including 2 RPM sensor ports, 1 flowmeter sensor port, and 5 temperature sensor ports (Sensors are required to be purchased separately. Sensor options: TEMS Temperature Sensor [04100427], Flowmeter [03040703] ). In addition, AES also provides 2 AD ports, allowing users to flexibly use different types of AD devices required in your airplane. At the same time, through the FBUS/S.Port feature of the connected receiver, users can monitor the telemetry data in real-time on the transmitter to know the aircraft’s operating status.
Why We Recommend This
The original Advanced Engine Suite is the straightforward choice for gas-plane pilots who want engine telemetry without the added complexity of the AES II — RPM and temperature monitoring on your FrSky radio screen, making engine health monitoring part of every flight. FPV Builds RC provides U.S.-based product support and setup guidance for FrSky products purchased through our store.
Frequently Asked Questions:
What aircraft is the FrSky Advanced Engine Suite designed for?
The Advanced Engine Suite (AES) is a multi-function engine management and telemetry hub for RC aircraft powered by gas engines. It centralizes ignition control, kill switch operation, engine temperature monitoring, and RPM telemetry in one unit — ideal for large-scale gas warbirds, giant-scale aerobatics aircraft, and single-engine gas models where you want live engine data on your FrSky transmitter without complex individual sensor wiring.
What is the difference between the AES and the AES II?
The original AES is a capable engine management box for most single-engine gas applications. The AES II is the second-generation model with expanded sensor port capabilities and broader support for complex installations including turbines and multi-engine setups. If you're building a straightforward gas-engine fixed-wing, the AES is a proven, cost-effective solution. If you need more sensor ports or turbine compatibility, step up to the AES II.
Which FrSky receivers is the AES compatible with?
The AES connects to FrSky receivers via FBUS or S.Port, making it intended for compatible FrSky receiver telemetry connections; verify the receiver port, protocol, firmware, and sensor wiring before purchase. Browse compatible receivers at https://www.fpvbuildsrc.com/frsky-receivers.
What telemetry does the AES send to my transmitter?
The AES streams engine telemetry including RPM and temperature data to your FrSky transmitter. On a Tandem X18 or X20 series radio running ETHOS, these values appear as live telemetry fields you can display on your home screen and configure with audio alerts — for example, an overtemperature warning if your engine runs hot under full power.
How do the sensor ports on the AES work?
The AES provides dedicated ports for temperature sensors and an RPM pickup, along with an ignition control and kill switch interface. Sensor data from each port is aggregated and transmitted to your receiver via FBUS or S.Port as a single telemetry feed. Refer to the FrSky AES wiring documentation for connector types and installation guidance specific to your engine model.
Can the AES work alongside other FrSky ADV telemetry sensors?
Yes. The AES can share the FBUS connection on a compatible receiver alongside other ADV sensors such as the GPS ADV, VARI ADV, or FAS current sensors. FBUS supports multiple devices on the same port, simplifying wiring on gas-powered models where you want comprehensive telemetry without running a separate wire per sensor.

Does FPV Builds RC offer setup support for the AES?
Yes. FPV Builds RC is a U.S.-based FrSky dealer and our team can assist with AES wiring, FBUS setup, and ETHOS telemetry screen configuration for gas-engine aircraft. Contact us via the site for project-specific guidance.
