Photo 1, blind nuts installed, control horn bolted in with double lock washers for depth in blind nust, balsa cover sheet glued in.
Photo 2 - 3, stab extension prototype in place and max travel is available.
Prototype can now be use to create the actual stab extensions, one left and one right. Note, that extension can not go past fabric on outboard side of rudder, so I may set up a physical stop rather than depend on a servo adjustment.
Ailerons

Photo 6 - 7, Leading edge sanded to shape and aileron cut to fit wing.
