Quick Trim with Aura Professional

Buttons and Status Window

This process transfers the trim in your transmitter into the Aura's subtrim.

  • Fly and trim in any selected Flight Mode. Land.
  • Leave Transmitter powered ON in the selected Flight Mode and set it aside.
  • Power OFF the Aura Professional.
  • Hold down the Button #2 and power ON the Aura. After about 5 seconds, release the Button. You should observe a slow-flashing Blue LED in the Aura status window.
  • Press and hold Button #2 for about 5 seconds. You should observe the Blue LED flashing more quickly. The trims are now stored in the Aura.
  • Power OFF the Aura. Center the transmitter trims.
  • You are now finished, and you can power up the Aura and fly!

Programming the Battery LEDs

  • Use the Aura Config Tool to set the thresholds for the red LED to come on. (hover the mouse cursor over key words for fly-out help)
    • The first 'higher' voltage sets the point where the Red LED will BLINK if lower.
    • The second 'lower' voltage sets the point where the Red LED will be ON if lower.

Battery Choices

Power for Aura 8 and 12 Professional

The choice of the battery/power supply is completely up to the user. Here are some suggestions based on our teams experience.

  • We are primarily using LiPo and LiFe 2-cell batteries with high voltage servos and accessories for our Pro Class aircraft
    • For smaller sized aircraft, each pack can be 1200 to 2500mAh
    • For medium sized aircraft, each pack can be 2000 to 4000mAh
    • For large sized aircraft, each pack can be 3000 to 6000mAh
  • 15C or higher discharge ratings are generally a good choice solid voltage under load.
  • EC3 Battery connectors should be used for high current capability.
  • Flex Innovations sells several batteries intended for this use. They are linked on the product page.
  • Our team generally does not use regulators. In the world of high voltage servos and lithium batteries, many consider the most reliable system is free of these regulators. In the past Spektrum (SPMVR6007, SPMVR6010) made ones that are since discontinued that can be used between each battery and the Aura Professional. The two regulators must be very well matched to keep the packs current draw balanced.
