Make from 3 mm rest plywood two triangular
pieces with 5 mm hole inside to fix the water
tube along the corner in the hull to the pump.
Adapt the triangular pieces to the shape of the
hull and glue them with Uhu Acrylit.
The pump will be placed on the RC board in
front of the battery box.
Fit the input and output tube (from the monitor)
to the pump
For the control of the pump you will need an
extra electronic switch for use at one channel
of the radio control.
V. Radio Control
For running your model on the water, you will
need a 2 channel radio control system with one
servo.
Stand Juli 2014
For the control of the motor you will need an
electronic speed control with forward and re-
verse control. This should have a constant
capacity of minimum 20 Ampere and should be
equipped with BEC.
The steering servo needs to be fitted to the
motor mount. Before assembly you should
check it is standing in the neutral position, as
adjusting later will be difficult.
For steering the rudder first the rudder lever
(97) needs to be fixed to the rudder shaft and
combined with the steering rod, made of parts
98, 99 and 107, then aligned. Please check
that the rudder turns to the left when the radio
command is left. If not you should be able to
revers the servo with the channel reversing
switch on your transmitter.
Fix the receiver to the front of the battery with
double sided adhesive tape.
The electronic speed control should also be
fixed with double adhesive tape to one side of
the motor mount. It should be positioned so
that switches or potentiometers can easily be
adjusted.
Join the cables from the motor with the cables
from the speed control in the shortest possible
way and solder together.
Please note the instruction of the speed control
for the adjusting and use of it. If a BEC is sup-
plied wit the speed control, you will not need
an extra battery for your receiver.
VI. Final Work
When all installation is done, please make a
final check all over your model. All joints and
installations should be checked for their clear
and stabile fit and if necessary corrected. Also
please make a test of the trim of the model in
the bath tub before you go to a lake for the first
run. The trim normally needs to be adjusted
with some weights of lead.
Before the first run on the water please make a
range check of your radio. For this place the
model onto the stand. Switch on the transmitter
and receiver, but leave the antenna of the
transmitter short. Now let the motor run full
speed and use the rudder lever slowly but
constantly left and right. If the rudder also
moves without any tremor, your radio works
well.
