Note: The Buddy is for aircraft without flaps only.

The RiteAngle™ Buddy is a modern, up to date system that accurately determines your aircraft’s angle of attack. This series uses an improved easy-to-understand LED display. This instrument is designed to FAA standards.
Green indicates safe, amber indicates caution, and red indicates danger.

In addition to the color of the LED’s the “arrows” show which way to put the nose to prevent stalling the aircraft. The Diamond of Green LED’s indicate the “On Speed” AOA, 1.3 Vso regardless of bank angle density altitude or any of the other variables where the airspeed is inaccurate. We introduced the LED display in 1995 and it has been so successful that all of our competitors now have an LED display available.

Vane (Refer to Image):
Next time you are getting on an airliner, look in the general area below the Captains and First Officers windows, about in the middle of the fuselage, notice a vane?? I had a vane in my nearly 19 years flying for a major airline, and in business jets several years before that. If it was reliable enough for me when I was carrying over 150 passengers plus my crew it is reliable enough for our homebuilt aircraft. The same polymer vane is used with the RiteAngle™ Basic as is used on our custom designed systems which cost $3500. We have wing, fuselage and jury strut mounts. These mounts will satisfy all types of aircraft from the simple ultralight to Jets and have been in use for over 11 years.

Note: Small vane (compared to standard vane) is more streamlined and smaller as requested by owners of aircraft cruising over 200 kts, however it requires the ball bearing sensor due to the reduced airfoil area (except with the Elite System). See Accessories.
