Product Description


ON SALE thru December 2021 at $349.95.

Our popular Angle Of Attack sensor and companion Radiant display gauge is back in production!

29647039126-f2c3d972d1-o.jpgThe Radiant Angle of Attack Sensor & Display System includes vane, sensor, LCD RADIANT color Display, and aural alert output, which sounds when angle is in the red.

 The vane is mounted on the leading edge of your wing (for tractor airplanes) or on the forward side of your fuselage (for pusher airplanes).  The Radiant AOA comes complete with fittings for either mount.

The actual angle of attack is shown in continuous digital format as well.  This is a differential angle from the base (cruise) setting.  The bar graph and the numerical value fall rapidly as the elevator is shoved forward.

All instruments are designed for a standard 2.25” cutout, and use approximately 100 milliamps of power from a supply of 11 to 14 volts.  All instruments are dimmable. 



  • Provides immediate feedback on Angle of Attack using weathervane probe. May be used to display Angle of Attack on experimental, ultralight, and LSA aircraft with manufacturer approval.
  • Displays Angle of Attack simultaneously in color coded bar graph form and in digital (degrees of attack angle.)
  • Loud aural alarm is included.
  • Harness is completely pre-wired! With 15 feet of cable.
  • Display weighs 1.6 ounces (50 grams)
  • Wind vane sensor mounts on 3/8” tube in leading edge (or flush mount version available.) Approximate length of 12”. Tail of weathervane should be at least six inches ahead of leading edge.
  • For flush mounting, remove the tube and unscrew the tube mounting base from the sensor.
  • For use in mounting to lift struts, use a much longer 3/8” tube (not supplied).
