Blast, 230's OPS has gone now,full needle deflection so cancelled late afternoon local flight.Next morning was able to reach thru and tap
sender unit with a spanner and it returned to normal so went for a fly,gauge showing normal 3.5 bar. New sender ordered.These VDO's appear fragile,Tacho hours go on the blink
quickly into a flight,Flip flop Microair won't monitor 2 channels now. Always something?
