Syd, the 7/16 inch play you refer to is for planes with the aileron weights. Ercoupe memorandum no. 57 say 5/16 inch for plane without the aileron weights. Most coupes today have the weights removed. I may be interpreting this wrong, but I think 5/16 inch play is right for most Coupes. 5/16 may be allright but I replace parts when the play gets to a 1/4 inch or less. Many Coupes at Oshkosh last year had no play in the controls.
