I have to say that I didn't like the S6 when I flew it. I flew a tricycle 912 powered machine. I found it had poor control harmony and I recall it needed an excessive amount of rudder to keep it in balance making it very tiring and uncomfortable to fly. It is however the only S6 I have flown so it may have been that particular airframe that flew like that.
