The FalconX AMRT (Altimeter/Motor Run Timer) only weighs 8 grams and is ultra compact to fit in nearly any fuselage is FAI approved, packed with precision sensors and other features that allow easy setup and use in F5J, F5K and ALES, and data logging your flight.

The FalconX connects between your ESC and receiver throttle channel, it uses a precision pressure sensor and 3 axis accelerometer to compile flight data. Configuration is done via Bluetooth, through the RC Electronics App for iOS/Android and allows EASY configuration for different flight modes, you can even create your own flight mode.
In F5J mode, the Falcon automatically cuts motor power after 30 seconds, unless the motor has already been switched off manually, and records the F5J Start Height.
In F5L mode, the module cuts motor power when either the preset altitude or motor run-time limit is reached.
You can make up your own modes too!
The built in TFT display is easy to read, even in direct sunlight and displays your max altitude and flight time after landing.
