The HK Pilot Analog Airspeed sensor is a perfect match for the HK Pilot Mega flight control system, giving you telemetry feedback and a more accurate way for the flight controller to determine airspeed over just GPS ground speed.
The MPXV7002 is designed to measure positive and negative pressure. In addition, with an offset specifically at 2.5V instead of the conventional 0V, this new series allows to measure pressure up to 7kPa through each port for pressure sensing or vacuum sensing
The included differential presser pitot tube and hose are perfect for most aircraft installations
