An instrument shop tells me that RC Allen electric gyros are very
rugged, so say a lowball 1,000 hours MTBF is good. That means then an
electronic gyro box by a little Mom & Pop company is assumed to be
10,000 hrs MTBF? They may be very good items to buy based on limited
user feedback, but how could they establish such a MTBF, or assumed by
us if Mom or Pop can't?
I have a couple Monroy air traffic detectors now, which work very
well, but it has to be a one-man company. He's the only guy who ever
answers the phone, and he (the design guy) once told me he outsources
the PC boards, so I guess he assembles them into cases, and answers
the phone, and works his web site. I'll ask their "QC Dept" about
MTBF next phone call... :-)
