Well...forgot to glue balsa blocks in the aileron for the hinges![&o]
Had to cut out a bit of the leading edge on 4 places and glue in the missing balsa. Then glue the leading edge bits in place again...an operation which wasn´t as bad as it sounds....
So now the Robart hinges are installed and this wing section laid aside while building the right wing panel.
PS:
Servo hatch has been cut out, and new hatch made of 2,5mm ply fabricated ready to be installed with servo and all.
