oke, just ordered a whole mess of stuff from stein...
I bought a 100 bag of both pins and sockets, although I'm pretty sure I need only the sockets for the garmin install. I bought 20 each of the high density pins and sockets. I also ordered some DB connectors of various sizes and genders to have on hand. I ordered pin insertion/extraction tools, some BNC connectors, and a BNC die plus crimp frame to handle the antenna install. Also 30' of RG-400.
Oh, and a gretz pitot mount
This airplane building business is expensive!
