Small Plane Stall Warning

If you need a wind direction warning circuit. Lines with ground on end is to show relative wind over plane wing and SPST switch (has flap to catch air stream) is in wing leading edge close to cabin and gets stall before outer wing stops flying. Normal flight the wind comes straight in and holds switch in open position. If wind direction is coming from bottom direction the SPST the switch closes turning on STALL lamp and sounding warning buzzer. Push control or yoke forward to get air moving over wing and plane flying again and warning system will go off. Flight instructor wants plane flying with minimum loss of altitude during stall practice. So? TIP: If power on plane stall, look on plane yoke where plane lock attaches to yoke shaft to lock flight controls on ground in neutral position. A simple hole drilled through yoke support and shaft to control yoke with a padlock was system on Cessna I was flying. Power on stall, push yoke in where hole in yoke is just past the neutral lock hole line up. This was little movement and breaks the stall. About the second stall you do this, the flight instructor is trying to figure out HOW you know distance to break stall and have low loss of altitude.
