I'm not familiar with Hartzell constant speeds. What is the recommended number of hours between overhauls? And if there is nothing major to take care of what is the typical cost? Thanks
Mike is flying a TWIN. There's no way I would fly one of our single-engine airplanes without constantly paying close attention to the propeller, including complying with the manufacture's recommendations on overhauls.
Just last week I inspected an RV-6 that had been flying since 2002, with no overhaul on the prop and no record of greasing it either! In fact, the owner said he didn't grease it because that way it would not sling grease.
Amazing what you hear sometimes.

Personally I don't feel like Lycoming and Hartzell's worst case scenero for environmental deterioration applies to most well taken care of and always hangered RV's. I like to let folks know what the recommended schedule is, but pulling a perfectly operating and properly maintained prop or engine due to calendar time, well it's just not what I would call a show stopper.
But to each thier own.
I do them religiously (500 hr mag inspections). Certainly worth checking all of the moving parts if you have an impulse coupling, as it failing can ruin your engine. The points always get replaced, and the engines seem to start better as well.

Totally with Vic on this one..
Gosh this thread is meandering like Ole Miss !

Mags - It is a Service Bulletin... Service bulletins are advisory and not mandatory. If the mag is not showing any issues, no mag drop etc then carry on. That said, at the rate most of us put hours on our motors, 500 hours will take many years ! Anyhow, we are all modern thinking futurists so should be on electronic ignition or EFI by now surely ?

Dumb question, but on all these hours do you typically use Tach time or Hobbs? Since our modern EFISs track both, and there is a decent difference, 15% or so.
