How to glide in a circular pattern? I was just curious as to how you would make a glider glide in a circular pattern ( or helical ). 

Will there be a large difference when considering a conventional glider vs a delta wing glider?
Assuming there is no wind, a circular pattern is most easily achieved by flying a constant speed and a constant bank angle. Maintain coordinated flight (no  skidding, no slipping). There is no difference in turn dynamics between a conventional glider vs a delta wing glider.
