I've been following this post with some interest as I used to own a
Russia AC-4c. I moved up to a Zuni II and also 1/2 of an LS-8. Last
year, I took a club member on a drag and drop. He flew my Zuni with
me in the LS-8. After a decent 200km flight, we were on a final glide
home. After 26 miles at 80-90 kts, the Zuni was 1000' lower than the
LS-8. So 5 times the price will get you a 1000' in 26 miles. The
Zuni will also thermal with a PW5. There is now another Zuni on the
field at Tucson. I really enjoy my Zuni.
