We use these on our airplanes, and they stay firmly in place - we didn't lose any of them during the tornado at Sun 'n' Fun 2011.
This double-sided stall warning plug fits any Diamond DA40 or DA20. This composite-reinforced, ergonomic stall plug is the perfect all-weather, easy-in, easy-out way to prevent insects and ice from clogging your stall indicator. The blazing yellow color of the firmly attached foot-long, ANSI-compliant and weather-resistant reflective remove-before-flight streamer stands out equally well in daylight or darkness under all weather conditions, so it can’t be missed during pre-flight inspection.
