Use the shaft coupling to connect the propeller shaft to the motor shaft.
Attach your preferred connectors to the power wires, then solder the
wires and capacitors to the motor terminals. Screw the motor plate (11)
to the motor.
Glue the wedge (10) to the underside of the hull bottom (7). Fit the prepared motor assembly through the slot in the
hull bottom (7) from the inside, then fit the shaft support (9) through the bottom (7) from the outside, sliding it into
the slot in the motor mount (11). You may need to trim the shaft opening slightly.
Caution: check that the motor and shaft rotate freely and smoothly, and make any adjustments required to the
openings in the hull bottom and the bottom edge of the motor mount.
Glue the servo mount (14 + 15) to the hull
bottom and the transom. Lightly sand the
joint surfaces of the rudder bush (16) to
provide a key for the glue, then insert the
bush through the holes in the hull bottom (7)
and the servo mount (14). Leave about 1
mm of the bush protruding on the underside
to allow a fillet of resin to be applied, and
glue it in place permanently. It is also
possible to apply glue from above through
the annular openings in the servo mount
(14).
Roughen one end of the rudder shaft (17) over a length of 40 mm,
and glue parts (18, 18.1 + 18.2) to the shaft using two-pack
adhesive. Sand the rudder to a streamlined profile when the glue
has set hard.
