Miniature air-speed sensor for RC plane or UAVs.

Miniature Pitot-tube with mechanic and electronics descriptions. In flight air-speed performance is compared to a GPS ground speed used as reference. Estimate wind strength and direction mixing GPS and Pitot outputs.

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.
