|Hinged pitot tube protector will open automatically in take off at speed of about 40 MPH and close automatically at end of landing roll. Fits pitot tube with 3/16" O.D.|
Cheaply made, the flap does not even cover the hole in the pitot , Nor will the nut tighen up enough to keep from moving it around with your fingers. I bent the small door some to try make it aline with the pitot hole, but then it still has issues with the door alinement. That defeats the purpose .
