Hi,

You only need to seal one side. Just use a strip of the covering film you used to cover the wing and aileron/rudder/elevator, or Dubro hinge tape, or clear strips cut from a laminating pouch. There are heaps of methods, (type into the search facility). Some don't use seperate hinges at all and use the covering as the hinge, (two birds one throw).

I would suggest you work on the underside and flex the control surface fully up and then attach you stirip to seal the gap. Check you still have free movement when you finish. Which way is up on the rudder???


Cheers,

Colin
