I did no modifications to the wing or elevator just simply hinged and horned the rudder, mounted 3 servos and strapped the battery and reciever to the fuse, the elevator already had the horn, I still remember how magnificant She flew free of any wire, this back in the late 70's. And of course I had balance the CG.
Aspeed I too am thinking of going back to control line I still have that McCoy and a ringmaster with a boken tail section to fix, still have a set of cables too! I'm going to climb up into the attic and get it tonight, that will certainly get me going, want to teach someone to RC and cable would be a good start.
