RE: ESM BF-110C ZERSTORER 95
You can still actuate the entire flap section. Make a ply plug 1/4" thick that will fit into the cavity at the inboard section where it was cut. Glue only into this section. When you slide the wing panels together, the 1/8" part of the ply protruding will fir into the outboard section. I can take pics if I made it sound confusing.
