Hitec Installation Notes and Equipment Selection

Note: This page is a Draft/Work in Progress. We request feedback from customers to make this page better based on your experience.

There are two ways to connect the Aura to your Futaba Receiver:

• S.Bus (Hitech implementation of Futaba S.bus)
• Traditional PWM Servo Connection

NOTE: Any recommendations are based on years of knowledge and product use and are informational only.

• We do not 'specify' radio installations. Consult your radio manufacturer for radio information.
• We test and support the use genuine Hitec brand equipment.

Hitec S.Bus

• Preferred way to connect the Aura to Futaba Receivers
• S.Bus - S.Bus is serial data on one wire (Digital). It gives the Aura knowledge of all of the available Hitec channels.
  • Aura will follow the Failsafe outputs of the Hitec Receiver.
  • Recommended for all aircraft types
  • S.Bus Input plugs into Aura Port B (Servo Bus)
  • Precise digital Data
  • Availability of all 8 Aura Ports as outputs
  • Receiver ports are also active and available for use

Notes on using Hitec S.Bus

• Hitec has elected to use the Futaba Header Bytes, so the Aura will work and/or auto-detect as a "Futaba S.Bus"
• Hitec has duplicated some of the Futaba data format such as Channel Order in the data
• Hitec has chosen NOT to duplicate other Futaba data standards such as channel center data, a and direction of travel away from center.
• Due to these variations, you must make some additional changes to your Hitec Transmitter settings in order to 'emulate' a Futaba.
  • Reverse Transmitter Channels
    • Reverse the Elevator Channel
    • Reverse the Throttle Channel (To use the Aura throttle port for an ESC, else as required)
    • Reverse the Flap Channel (If needed to match Futaba, or as required)
  • Adjust Transmitter EPA (Travel) Settings to make equivalent to Futaba at +-125%
    • Aileron Left and Right to 133%
    • Elevator Left and Right to 133%
    • Rudder Left to 140%, Right to 133% (output not symmetric in Tx's we evaluated)
    • CH5/Gear to 100% in both directions
  • Subtrim Transmitter Settings (To emulate Futaba Centers, Aura expects CENTERED Data)
    • Aileron to +7
    • Elevator to -7
    • Rudder to +7
    • Gear to +7
    • Flap to +7
    • Throttle to -7

Traditional PWM Servo Connections

• Least preferred
• Recommended for all aircraft types.
• Supports virtually all receivers
• Limits port availability. Typically Aura will be configured with 4 inputs and 4 outputs with PWM.
