I try to do all of my hinges either with tape or clear covering, Sometimes it is just to hard to do the rudder. On most ARFs from Hanger 9 the tail just fits so well it seems like a waste of time, But the ailerons most defantly. However I am sure there are far better builders out there that can get them perfect right from the start.! BTW I got to look at a new Hanger 9 carden yak today the hinges are the pin type and are taped from the factory.
