About this product
ASPD-4525 is a digital airspeed sensor running on 4 to 6 V, listed for MATEK F405-WING, F411-WING and F722-WING flight controllers. On a fixed wing it gives the controller a real airspeed reading instead of a GPS ground speed, which is what stall protection and auto-throttle logic actually need. Whether a pitot tube and cable are in the box is not stated here, and the probe must face forward in clean air.

Pros & cons
Pros
- Real airspeed lets the controller act before a stall instead of after it
- Digital output on a known MATEK part number, so wiring is documented
- Wide 4-6 V range works off the 5 V rail most wing builds already have
Cons
- Listed for MATEK wing controllers; other flight controllers may need different firmware support
- Pitot tube and cable inclusion is not stated, and a missing tube stops the install
- Requires a clean, forward-facing probe position that many fuselages do not offer out of the box
