GPS Foldable mast for FPV airplane

Here is my final version (V3) for a foldable mini GPS - naze Mini - mast for a FPV airplane.
Installed and tested sever hours. This last version overcomes the brittleness of my previous that were destroyed in the bottom part of the mast.
Total height is 65mm from the support good enought to avoid EMF without causing a lot of drag.
Folding movement is allowed only in one direction so during transportation or hard landing GPS may be preserved.
