FrSky Advanced Engine Suite II – AES Telemetry & Ignition Control System

FrSky Advanced Engine Suite II (AES II) – Engine Management & Telemetry Hub

The FrSky Advanced Engine Suite II (AES II) is the central control hub for your gas engine and telemetry system. It connects your ignition system, receiver, and engine sensors into one integrated module, allowing you to monitor fuel flow, RPM, temperature, voltage, and engine status in real time from your transmitter.

Key Features

• Central telemetry and engine management hub for gas-powered RC airplanes
• Replaces separate ignition battery by powering the ignition system directly
• Built-in ignition noise isolation to help protect receiver signal integrity
• Real-time telemetry data through FBUS / S.Port
• Supports RPM, fuel flow, temperature, and AD sensor inputs
• Designed for use with FrSky telemetry-compatible receivers
• Helps simplify wiring and reduce separate onboard components
• Ideal for large gas aircraft, warbirds, scale airplanes, and complex engine setups

Advanced Sensor Interface System

The AES II module is equipped with a wide range of sensor interfaces, allowing for full engine monitoring and system integration:

• 4 RPM sensor ports (2 sets of dual inputs)
• 1 fuel flow sensor port
• 7 temperature sensor ports (4 × PT100 type, 3 × TEMS type)
• 2 analog (AD) ports for additional sensor expansion

Through the connected receiver using FBUS or S.Port, all telemetry data is transmitted in real time to your transmitter, giving you complete visibility of your aircraft’s operating status during flight.

Specifications

• Dimensions: 50 × 46.4 × 18 mm
• Weight: 53.5g
• Input Voltage: 4.5V – 13V
• Connector: XT30
• Telemetry: FBUS / S.Port

How It Works

The AES II connects between your receiver, ignition system, and engine sensors. It collects real-time operating data from connected sensors, then sends that information through your FrSky telemetry system so it can be viewed on your transmitter.

This allows you to monitor critical engine information such as RPM, fuel usage, engine temperature, voltage, and overall operating condition while the aircraft is in use.

Build a Complete Engine Monitoring System

• Fuel Flow Sensor: Track fuel consumption in real time
• RPM Sensors: Monitor engine speed and performance
• Temperature Sensors: Monitor cylinder, exhaust, or engine bay temperatures
• AD Devices: Expand monitoring with compatible analog sensor devices

Replaces Multiple Components

• Separate ignition battery systems
• Standalone telemetry modules
• Basic ignition kill switch setups
• More complex multi-device wiring layouts

What’s Included

• FrSky Advanced Engine Suite II module
• Connection cables

What You’ll Need

• FrSky telemetry-compatible receiver
• Compatible sensors as needed: fuel flow, RPM, temperature, or AD devices
• Gas-powered RC airplane engine setup
• Compatible FrSky transmitter for viewing telemetry data

Best Use Applications

• Gas RC airplanes from 30cc to 120cc+
• Warbirds with complex engine and telemetry setups
• Scale aircraft requiring real-time engine monitoring
• Large models where ignition reliability and telemetry visibility matter
• Pilots wanting a cleaner, more integrated onboard electronics system

Why This System Matters

A large gas-powered RC aircraft often relies on several separate systems: ignition power, receiver power, RPM monitoring, temperature monitoring, fuel tracking, and telemetry. The AES II brings these functions together into one integrated engine management hub, helping reduce wiring complexity while giving the pilot real-time operating data.

For serious gas aircraft setups, this type of system provides better visibility, cleaner installation, and more confidence during flight.

Modeler’s Tip

Pair the AES II with the FrSky Fuel Flow Sensor, RPM sensors, and temperature sensors to build a complete gas engine monitoring system. This setup is especially valuable for large-scale aircraft where fuel usage, ignition reliability, and engine temperature are critical.
