You can use the dubro hinges, but instead of using the supplied pins use music wire which is almost as long as the control surface.Simply make a j bend at the end, cut a small slot in the end of the control surface.Sharpen the point on the j bend so you can push it in so that the wire is recessed or drill a hole for the wire.After all the covering is done and all of the control surfaces are on then put a small piece of covering over the wire at the end of the control surfaces.This way you can pin the hinges and still be able to remove the control surfaces in the future if needed and the wire fills the gap between the control surfaces.Also if you have any hinges not working freely you can replace them since they are installed before covering.You can also do this with robart hinges.You can buy them without pins and do the same set-up with the music wire.Just be sure to use the right size wire.Buy wire that is as close to the original size as possible.Normally it will be a few thousanths smaller.This kind of set-up works great and it makes repairs easier.Simply cut the covering and pull the wire out.
