Newbie here... but, fwiw, I had over two decades of full time soaring
ending up owning and running a full time soaring center in central
texas (windermere soaring) until I completely flamed out and padlocked
the hangar doors in the early 80's

I'm currently trying to revive a quarter century old project of
writing a soaring textbook, a project that I began shortly after I
closed the school.

I think I have a good start and working this week with the idea of
publishing chapters online as I finish them. As I am working on one
on patterns, I find I have no good info on _full spoiler_ sink
rates... think a 2-33 at 55k is around 7/1.

Can anyone here help with figures for full spoiler sink rates for the
2-33 and current trainers at a general pattern speed (60mph?)

Thanks in advance,
Beverly Howard

Just ran the numbers and that looks _way_ too low... from the
measurements of our pattern, it would require full spoiler approaches,
so, assume that it is much lower... 4/1 perhaps, but 2-33 manual and
searches come up devoid of solid figures.

Thanks again for your attention to this post,
Beverly Howard

Yep, that's about how I remember the 2-33.
See ya, Dave

You might have a look at the Idaflieg publications or ask them directly
). I have seen speed polars with full spoilers for
several gliders in one of the older reports (70s or 80s).
