I used 3 inch aluminum duct that I picked up at Home Depot, it was available, inexpensive, and did not affect the AHRS. Eugene Long Lancair Super ES glong2@netzero.net """ 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? Bob Comyn """
