Why do gliders usually have a long wingspan with a short wing chord? I would think that the long wing span would create more drag than a shorter, wider wing with the same surface area.
I figure I am most likely wrong but can someone tell me why?
I am building my first airplane which is a motor glider and I think I am going to change the wings and give them some dihedral but I am trying to figure out what would work best as far as wing span and wing chord. right now I have a 60" WS and 7" chord with 2" ailerons.
