Rigid point for aileron horn
The BL 125 rib is where the aileron horn will be mounted. The rigid point for this
mount can be installed more easily before gluing the ribs to the wing. Take the aluminum
rigid points provided, demarcate their position on the outer shell of the tank (this rigid
point is centered on the rib and with the front face aligned with its internal flange, see
figure). Cut the casing and dig the core in these positions. Prepare a FLOX paste and glue
this hard spot in place. Roll in place with 3 layers 1-inch BID overlay.

Top coat bonding
Replace all rib and spar sections following the modifications and ensure that no
modifications made previously created any problems with the fit. When the placement is
satisfactory, gluing can be started. Again, this is accomplished by working from the rear
spar to the front. Prepare the top coat and face bonding areas of the sections to be bonded.
