There are alternative places to mount the XRX. However, placement depends on the aircraft structure and material. On an aluminum air_frame_ such as a Vans, XRX needs to be mounted in a place where the air_frame_ is below the antenna hump, which is why the glareshield is the optimum place. If your canopy slides, there's little room in the back behind the seats. If it hinges, you may have some space on the turtledeck. To be certain, send me a photo of your cockpit and we'll see if we can determine the best place. I have heard of some RVers placing XRX in the fiberglass rudder cap with success. The only wiring needed is ground, power and data. Be sure we do a simple free modification to allow the XRX to automatically power on and set itself up for remote mounting such as this.
