According to Radio South instruction, Radio South hinges should be CA glued to the control surface first, let dry, and then CA glue the other half(s) to the LE (see Radio South's instruction photo below).

This is different from most of the CA hinging methods I read: put the control surface in place first and then apply the CA to all hinges.

I wonder if the Radio South method allows a strong bound at the LE side. How did you install the Radio South CA hinges?
