For demanding telemetry or model identification applications the use of an appropriate air data boom is required, a DIY well tested design is here presented.
Angle of attack wind vane, or alfa beta drawings are available here.
The presented data boom can measure:
Figure 1: Miniature DIY Wind Vane detail, JLJ and GC 1 Counter weight, 2 Fin, 3 Main rotation shaft, 4 Bearings, 5 Potentiometer, 6 vane body
Angle of attack and angle of sideslip are measured by mean of a mechanical wind vane
. The vane deflection is converted to a electronic signal by mean of angle sensor.

The angle sensor can be a simple potentiometer or a performant, hall sensor based, rotation sensor.
Consult this page for details about sizing the vane. The drawing of the vane components are reported here below:
