Miniature airspeed sensor for RC plane and UAVs.

Build and test of a miniature Pitot static (Prandtl) tube. Parts and electronic design are described. In flight airspeed performance is compared to a GPS ground speed used as reference. Wind speed is estimated to remove bias between airspeed and ground speed.

MATEKSYS PDB-XPW Dual BEC & Current Module tweak to increase current measurement sensitivity

Adapt the MATEKSYS PDB-XPW power module for quad rotor to fit electric RC plane with lower current requirements. Change current measurement range by replacing one single resistor from the Op-Amp current measurement circuit.
