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:

Angle of attack, AOA
Angle of sidelslip, AOS
Static pressure, $P_s$
Total pressure , $P_t$
Outside air temperature, OAT

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:
