I used Robart hinges on my Sig 1/4 Clipped Wing Cub and the Ercoupe's I am building now, I will not use any other hinges after useing these. If you decide on Robart hinges spend the few extra dollars to get the Robart Hinge Drilling Guide. The hinges are easy to install and work much better than C/A hinges and will outlast any other hinge in my opinion.
Good Luck!!
