Flex Innovations Aura 12 Professional Flight Control System

In stock

The Aura Professional line has been carefully engineered and optimized for larger and more complex aircraft while simplifying installation. The new Aura Professional case is exquisitely CNC machined from aluminium and hard anodized. The new case design also features mounting lugs with grommets and slots for hook and loop straps so that it can be easily well-secured to any air-frame.

Product Information

The Aura 12 Professional incorporates two dedicated, isolated battery power connections with high-current handling capabilities and EC3 connectors. The system can be switched on and off with an included fail-on soft switch. On-board LEDs confirm each battery is online and general system status. Additional LEDs indicate the voltage level of each servo battery to warn of low voltages at a glance.

Two standard Servo connector ports (Port A and Port B) are available for Digital Receiver Input connections such as S.Bus, SRXL, SUMD, EX-Bus, etc. The Aura Professionals also supports automatic dual Receiver selection for ‘single receiver’ systems such as S.Bus. Automatic Receiver selection increases redundancy and provides greater radio path and antenna orientation diversity. The Aura Professional can also provide configurable S.Bus or SRXL Output to enable compatible servos and devices.

The Aura 12 Professional offers 12 Servo Ports which are available for standard PWM Servo signals. Every Servo Port on the Aura can be customized to support complex aircraft control surfaces such as Elevons, Flaperons, Canards, V-Tail, Tailerons, etc. Each Servo Port can also be configured as Input to capture the PWM channel from the Receiver for a traditional setup. The Aura Professional capability is maximized when using a modern, Digital Receiver connection such as Futaba or FrSky or Hitec S.Bus, Spektrum SRXL, Jeti UDI or EX Bus, JR DSM Mode A or B, or Graupner SumD to allow up to 24 internal channels. Individual Buttons included on the Aura Professional eliminate needing bind plugs and make using features like Quick Trim easy!

An external gyro sensor port is provided. The optional external gyro sensor is available separately and is hardened against the noise that can be generated by large turbine jets.

Like the standard Aura 8, the Aura Professional offers the same great stability and a direct, connected feel that does not interfere with the pilot’s commands. Each of the Aura’s settings (gain, stick priority, dual rates, expos etc.) can be tuned specifically to the pilot’s preference. Each Aura Flight Mode can even have two simultaneous gyro settings for advanced features such as thrust vectoring nozzles, nose wheel steering, or canards. Gyro corrections can even be applied multiple servo ports such as in a Live Wing setup where Roll gyro corrections are applied to the Ailerons AND the Flaps (most gyro systems can only apply Roll gyro correction to the programmed Aileron servo ports).

Whether you fly a medium to large size jet, warbird, sport or aerobatic airplane, the Aura Professional is sure to make your airplane feel larger, smoother and as if it were flying in less wind!
