I use the Digiflite II and distance does not seem to be a problem. The gold
box is a Crossbow AHRS including magnetometer and GPS; it is used with the
Cheltons although I believe it is also used with AFS and Optech. The black
box is the GRT magnetometer for the Sport which has its own internal AHRS
with the display unit.

That is similar to what I was thinking about. I assume you have an
autopilot servo and since you are flying, it must be far enough away. I was
thinking of going a little further back.
I'm curious, whose unit is that? AHRS and Magnetometer or just one of them.
As I recall, you are not using the Van's belt setup.
Thanks.
