The air duct hose supplied by Lancair that runs from the rear NACA forward
has wire in it and is therefore magnetic.  My Chelton AHRS is located on top
of the FS171 bulkhead and Kirk says that that hose will interfere with the
operation of the AHRS.

Does anyone know where I can get some 3" ducting hose that is non-magnetic?
