all,
I am experiencing large swings in the compass of my RV-8. It is a panel mount,
not vertical, from Vans. There is nothing really near it that carries
substantial current, just a G meter and the VOR indicator head. A Garmin 430 is
about 8 inches away. I have all of my fuses/breakers on the side panels so the
main panel has little on it with current flow. Could the rollover hoop be
magnitized? If it is, why doesn't the compass show a constant error rather than
swinging? Or could the (Chinese) compass just be junk?
Confused

I used a bulk tape eraser to degauss the roll bar and the forward canopy
frame. This solved my compass error problem. After degaussing the compass
error correction screws were enough to zero out all remaining error.
If you do this make sure you take out all panel electronics first, including
CDI heads and such.
