*I will use english to allow ours foreign members to take part of this discusions. During the visit to Bahia Glide, Gugui introduced me to a technique on thermals was quite strange (for me), on that time. In fact i were not able to see any advantage using the Outside foot (when you use oposite rudder on the thermals keeping the chord drifted (a little) to outside of the turn. After flying a lot in Condor trying it, i think i found the balance and the reasons some guys defends that technique. The technique is a way to counteract the tendency of the nose of the glider to slips into the turn and point all the fuselage to a nose down attitude, decreasing the altitude gain. What is normal? I think normal procedure is to keep coordinated turn and conteract the nose down tendency with little aileron + elevator continuous (almost) correction. What is the Outside foot technique. Is simple do the samething just using a continuous rudder preesure to keep the noose high. In the end the question is: What is most effective? What is the less drag inducer technique? The guys who defends the outside foot says the aileron will cause a lot of more drag than the rudder. Questions for interaction: 1) What is you opinion? 2) Is there any real data about maximum drag force produced by ailerons and rudders? (any glider will give us a example). 3) Is there anything about this theme in the literature? Regards, Cristiano
