I installed the compass today. I had this one lying on a shelf for a while now but never got to install it. Since I'm now waiting for the wheel pants to come from Sonex, it was a good time to do this job now. This is an SIRS compass that can be hung upside down from the windscreen in case of the Sonex. It can be attached to most surfaces using just the 3M adhesive that comes with it, however you can install some screws/nuts as well to make it more secure, which is what I chose to do.
