I broke out my Protege, been in moth balls for a year. Converted it to tail dragger, put an OS 70 on it and flew it this weekend. Flys just the way I remembered it, maybe a bit under powered with the 70, an 82 or 90 may be better. But it's a great relaxing plane to fly, lands on rails. I also put an 18 oz tank in it to extend flying time.
