120 I thought but my experience there was long ago.

I think you are right about the 120 days,...anybody know how much it costs
to have one repacked? Do we have any parachute riggers on the group?

Is it? Why would it be shorter than any other engine TBO? Do you have a
reference? If my engine's running out, I'd like to read up on it and find
out what's different.

Yes, hundreds of owners who fly competition aerobatics.
In competition aerobatics you are constantly and repeatedly going from
full throttle to idle. There is no in between setting.
The only time you fly at a given power setting for any length of time is
when you are flying from one contest to another.

Sure, I understand that part, but where is there a Lycoming or FAA reference
that says an engine installed in an aerobatic engine has a shorter TBO? The
reason I ask is that, to my knowledge, all the Pitts drivers here in the UK
are operating on 1500 or so hours (mine's so short of that mark as to not
have to even worry about it for a while yet). No one has ever mentioned a
shorter TBO requirement and, even with binary throttle application like
you're talking about, I don't hear of too many of my colleagues having to do
any more maintenance than anyone else.

The answer to the $300/hour Pitts must lie someplace else...

Heck!
That's pretty reasonable , may have to find me a chute!

Typical repack costs for emergency chute are $25 - $35 in
the NY area.

Do not spin this aircraft. If the aircraft does enter a spin it will
return to earth without further attention on the part of the aeronaut.

All I can say, is figures lie, and liers figure. I'm not calling you a
liar, since I know you are just quoting. g

Seriously, I can't see how that could be true. The same things that a
regular flight can still happen, and added to that, sometimes the wing is
over stressed and folds, or there is spacial disoreintation, and flight
finds ground, or......

If this is true, why is it required to wear a parachute? I could go on.


Ground handling a Pitts is another thing, though.

Perhaps I should have said that the engines need to be rebuilt after
600-700 hours.

Obviously you don't fly aerobatics yourself.

Same question applies as that is what TBO is.

Actually, TBO is the manufacturer's recommended time between overhauls. The
engine may last a lot longer than that if it's babied. If you abuse the engine
(and competion aerobatics abuses engines), it will have to be rebuilt long
before TBO. I don't know if John's figure of 600-700 hours is correct, but it
wouldn't surprise me.
