Our group is investigating a summer competition using foam gliders from Walmart or Hobby Lobby converted to two ch RC. They will be piggy backed aloft to a prescribed altitude and released and longest time aloft wins. The only requirements are the 54" one design airframe and two channels. Control is the choice of the builder as well as adding di or polyhedral.

The immediate task is to build the first and test for adequate strength to endure the launch ride. In an effort to keep it simple, I'm wondering if elevons (on the wings) would provide enough pitch control on what is otherwise a conventional air frame, given that flying will require light air and not a lot of pitch control will be needed if the plane is otherwise in good trim.

Any thoughts?
