On a trip back to the Bay Area from Las Vegas this past June, I got my
'77 Archer up to 17,000 going over the sierras just south of Mt.
Whitney. The climb over the desert was tough and slow. The
temperature out of Las Vegas was around 110F. Anyone know what %
power I was running up there?

I frequently take out 78 Archer II to 10-11,000 ft. Not for
short trips, of course, but for 300+ miles and if the
winds are reasonable, it works well. Gets me that much
above the low level clouds and turblance.
I'm only climbing about 250-300 fpm torward the end,
but no controller has complained.

This is slow for an Archer, but 10,000 feet means nothing without

150mph (130kts) wide open throttle at 8000ft DA.

Btw, how do you guys get that high with a non-aspirated and
not-so-powerful engine? Do you do it even with full load? (it seems that
all Americans fly Archers at about 10k ft...

I'm interetested in what kind of airspeed/fpm you use and how do you
lean in climb?

I don't usually go higher than 7000-8000 ft (with full load) and that is
difficult enough in my opinion I try to maintain at least 300fpm all
the way, with airspeed 80kts and leaning gradually after 5000ft.
