Do you have a name or two of full scale planes with thick, square TEs on any surface? I've never seen any ever and would really like to see what thickness is being used.
The Gloster Javelin, a British all weather interceptor of the 1950s, had a thick TE on the ailerons, about 15-20 mm thick. This one is at the museum at Elvington, York.
