check from the transmitter that the motor spins in
the correct direction. If not, reverse the wires at
the motor terminals; on no account reverse the
battery wires!
•
Since the water-cooling coil (part 16) is made of
conductive aluminium, it is essential to insulate
the motor terminals
accomplished by
insulating tape (part 17) round the motor
terminals. Slide the water-cooling coil over the
motor, taking care not to damage the insulating
tape or push it out of position.
•
NOTE: the propeller shaft in the model is longer
than required; this allows it to be shortened to
suit different power systems or shaft couplings.
Assemble the shaft coupling (part 18), and screw
it to the motor shaft. Install the motor in the motor
mount inside the hull. Angle the shaft coupling as
shown in the photo. Shorten the shaft in such a
way that there is a clear gap of about 2 mm at
the connection. Lubricate the shaft with plenty of
grease. The shaft coupling can now be screwed
to the propeller shaft.
•
Locate the 2 mm Ø steel rudder pushrod (part
19), and cut it to a length of about 160 mm.
Cautiously slide the rudder pushrod through the
rubber bellows
connectors. Set the servo and the rudder to
centre, then tighten the screws in the two swivel
connectors to clamp the pushrod permanently.
•
Screw the propeller (part 20) onto the exposed
end of the shaft, and tighten the locknut against
it.
•
Attach the speed controller to one inside face of
the hull using a piece of Velcro (hook-and-loop)
tape (part 21) about 20 mm long.
•
Connect the rudder servo and the speed
controller to the receiver (part 22), and then
mount the receiver towards the stern of the hull
using another 20 mm length of Velcro tape.
•
Drill a 2.5 mm Ø hole in the stern end of the hull
in the approximate position shown in the photo.
The exact location is not critical; the only
important factor is that you can easily gain
access to it inside the hull. Form a 3 mm Ø loop
in both ends of the 0.5 mm Ø steel wire to form the external whip aerial (part 23). Shorten the flexible
aerial attached to the receiver by the length of the external aerial (approx. 350 mm). Solder the cut
