My Hobbs time is a little over 500 hours now, but tach time using 2500 RPM (my usual cruise RPM) is around 432.
What do you all use for the interval for the recommended magneto overhaul? Tach or Hobbs? I know tach time relates more closely to the theoretical grand total number of revolutions, which is what *should* determine wear and tear, but is that a good measure? Or just the total accumulated time that the engine (and hence mags) are turning?
