Sukhoi SU 31M
Instructions
Insert the HR2-HR3 into the two holes on one
side of the hatch with the HR3 to the outside
next to the fuselage. The HR3 should be
flush with the top of the fuselage and the HR2
extends up ½”. Clamp into place.
Take the HR1 and glue to the backside of the
HR2 and to the hatch floor. The hatch
retainers should now be glued securely to the
hatch floor. Be careful and don’t glue the
hatch floor to the fuse top. Do this for both
sides.
Using two short sections of ¼” dowel, align
the H1 with the F1A and glue H1 to the hatch
floor. Glue the dowels in H1. Be careful not to
glue the hatch floor to the fuselage or to the
F1A. Now glue H2 and H3 to the hatch floor
in their slots. Make sure they are centered on
the floor. Glue the CR former at the rear of
the hatch floor. It should be .040” smaller
around the edges than the turtle deck. Sand
to fit. Now glue the ¼” balsa stringers in
place. The two outside stringers run from H1
to CR. The other stringers just go from H1 to
H3.
Prepare the sheeting by cutting two pieces of
3/32”x4” balsa to 15-1/2”. Take a 36” piece
and hold In place on the fuselage along the
top edge of fuselage and mark the angle at
the turtle deck and the front edge flush with
H1. Edge glue the 15-1/2” piece to the piece
you just cut flush with the front.
