There were only a select few Cessna 150's and 152's available to me that I would spin. Most were just a little to sketchy in normal flight much less a spin. I also would not spin cherokees even though technically they were allowed within set CG/weight ranges. The Warriors are not allowed, as I understand it they were not spun due to fears of the new wing potentially blanking out the tail so they never even tried to spin it. That is just what I remember hearing, but I never researched it. Again they are a very useful learning tool, but you need to be very confident with the airplane and pilot, and don't push your luck.

P.S. Eddie I know what you mean about other peoples planes. I flew into a little airport just south of Memphis to pick up a Warrior for a new lease back for the school. I left late in the afternoon and flew IMC for the first 3 hrs of the flight. At the end of the flight I was picking up what I thought was moisture on the windshield about 10 miles out. By the time I landed the whole left side of the airplane was covered in oil and I had just under 2 qts. of oil left. Turns out a push rod bent suddenly at the end of the flight and broke the seal on the pushrod tube allowing oil to start pouring out. Had it happened in the middle of the flight I would have been in solid IMC at night with no engine. I shudder to think.[:@]
