Ron's newest RC plane design

Flies great but it just won't turn. This model is a great example of what happens when you try to use rudder as the turn control on an aircraft which has almost no dihedral. The lack of roll coupling means that the rudder is almost completely ineffective and even though Ron held on full right, the model kept flying straight and true.
Ron's now planning to fit ailerons, after which it should fly very nicely.
