hi all,
I have had a non-responding compass since building the plane (RV- and finally
decided to do something about it. Removing the compass and walking around with
it shows it to be working OK. Get it within a foot of the roll-over hoop and it
goes nuts. So the hoop is magnetized. I have tried to degauss it with a TV type
degausser without success. I think that the degausser has to surround the metal
to work, thus the hoop would have to be removed or deguassed before installing
it. I am not about to remove it.
Anyway my solution was to install a remote compass. Good solid WW2 technology.
The transmitter sets in a hole cut in the aft part of the baggage compartment
floor. The front indicator is just a needle operated by a servo, connected to
the transmitter by 4 wires. There is a small inverter to supply 25 volts at 400
Hz. Works very well, just kind of pricey. This compass has aggravated me for so
long I am glad to pay it.
