I understand that the XRXi development has now been dropped.
From my post in the "Sales" forum you will see that I have posted an enquiry ref. remote mounting in an RV8. We have mounted a remote aerial in the fibreglass fin top in anticipation of the release of the XRXi, but have seen in the post above that you believe that the XRX will fit in this space.....it looks very tight......

Have you got any reports of whether modification is required to make this work?

Have any of your users had any success in mounting in the space behind the rear seat above the baggage compartment?

How important is levellingthe unit?

I look forward to hearing back from you.
