Pilots in the second group at Emu 2 get to fly and get up to 9200'. Cloud Base is 9000' and the winds are strong. Great for a flat land flying day. RCS flaps Bob Baier and Josef Guggenmos are doing well on Guggenmos's RCS glider. The glider features a dynamically operated horizontal tail and pilot operated flaps.
Tails placed on other topless gliders are passive and stay in one position.
They are placed there to help prevent tucks and tumbles. If the pilot becomes unweighted, like in a tuck, the angle of the horizontal tail changes. The flaps are pilot operated and use a carbon fiber panel just as the Exxtacy does. If you look at the next photo you can see where the panels go in to form the flaps. I have heard now that there are a number of new rigid wing gliders in the works.
