I'm working on getting my new Pixhawk2 up and running in an RC plane, and I keep running into the problem that I don't have specific connectors or cables for making connections between the various components.  For example, I don't have a 3-wire cable to connect the PPM receiver to the RC IN port on the Pixhawk2.  Is there a vendor that stocks the wide variety of connectors needed for both RC gear and the Pixhawk2?  I don't mind making my own cables if necessary (though I'd prefer to buy pre-made, if the cable exists).
