Mount designed to hold an Eagletree pitot tube and secure it to a foam plane.Install the static and pressure lines onto the pitot tube before you insert the tube into the mount. Route the tubes down the channel in the mount (making sure you don't kink them) and out the bottom. The mount halves can be secured with a M3 bolt and nut. You may want to glue the front of the mount (where the tube exits) together. I was trying to design a streamlined positive retention/clamp for the front but gave up. I zip tied mine - looks crappy but does the job. The barb on the bottom of the mount helps to secure it in the foam (I used gorilla glue on mine).
