Lightly tack glue the cowl ring assembly jig on top of the
inside (blind nut side) of 1/8" plywood C1. Place 1/8"
plywood C2 onto the jig and lightly tack glue. Wrap the
1/32" plywood strip around the C1, C2 pieces and glue.
A�er the glue has dried, sand the plywood even with C2 if
needed.
Glue and stack C3, C4, C4 and C5 onto the cowl ring
assembly jig. Put some weight on top and allow to dry.

This builder likes to make a fixture, copied from the plans,
to sand the proper radiuson the cowl balsa. This builder
also added two 1/8" wood dowel pins to the rear side of C1
that went into the F1d former at the datum line point on
each side.
The cowl is held onto the fuselage via the Neo Magnets at
the top and the 1/4" 4-40 machine screw at the bo�om.
A couple more items and the fuselage will be pre�y much
finished. A 1/32" plywood ba�ery hatch is furnished in the
kit. It can be secured in your favorite manner. The plans
show 1/32" plywood tabs slipping under the forward
landing gear mounting plate. This requires an 1/8" spacer
between the tabs and the ba�ery hatch. The photo below
will show how this builder mounted the hatch. It lays
on the outside of the fuselage sides and over the front
wing strut mount. This mount needs to be sanded down
quite a bit as well as rounded to the fuselage curve. This
builder choose to also have a hatch to access the servos
and receiver. The ba�ery hatch is held in position by Neo
Magnets. The a� hatch is inset into the fuselage and held
with 4-40 x 1/4" wood screws. Two finger holes were put
in the ba�ery hatch to take the hatch off and also to allow
cooling air to enter or exit – whichever.
This is a good time to mount the rudder and elevator
servos while the fuselage is open.
The tail skid TS1 and 1/8" plywood tail skid can be
assembled now, but not a�ached until a�er the fuselage is
covered. Remember keep the tail lite.
