I keep thinking of people telling me how simplistic and maintenance free air is while I'm rebuilding retract valves, mixing up dish washing liquid so I can find leaks and trying to get the kids to be quiet so i can listen for hissing and wondering if my compressor is in the garage or the trailer while I'm at the field with just my truck.
FWIW I had about 200 flights on one of these with Robart 615 air and robo struts w/o any more aggravation than I would expect but if I were doing it today I'd go electric.
