Correct. Somewhere back in the early 60's if memory serves, and it probably doesn't, the Cessna 150 went from a uhhmm, vertical, vertical sabilizer to a swept, vertical stabilizer. The C150 pilots, mostly CFI's, said the deterioration in handling was definitely noticeable. The design change was made so it'd look more like a jet- even tho the high wing and struts remained.
