Had a Kougar in the late '70's and loved it so much I bought another one about three years ago and fly it often! I have an OS .46 FX on it and I built it light. It has almost unlimited vertical performance. I probably have over 200 flights on it now, in fact I need to replace the light weight wheels because they are so worn. It is very dependable - stable slow or reasonably aerobatic. I don't know how experienced of a flyer you are, but I would recommend it as a great low wing airplane. BTW, it flies like its one rails on approach and landings. Keep it light and make sure the CG is right.
