 My AHRS (Crossbow 500) is located above the leading edge of the horizontal
stab. Other wires go thru the floor of the tail, so they appear to have no
effect on it. The only interference I have found is when I push full down
elevator and the counterweight arm swings near the AHRS. That creates a 2
degree right deflection on the AHRS.
 
 How many times are you going to use full down?
