Move the transmitter stick in a circular path, and check that the control lever does
not foul the guide sleeve at any point. If there is any contact, you will hear a rattling
sound from the VSP. If this should occur, reduce the end-points for the corres-
ponding servo slightly. Movement of the VSP’s control lever must not generate
noises of any sort.
•
Important:
never operate the boat without the travel limiters in place, as they
protect the VSP and the servos from overloading.
•
If the control lever strikes or rubs on the guide sleeve, the mechanism and servos
will be under excessive strain, and this in turn will cause the bearings to leak. The
ball-links on the control lever will also wear much more quickly under these
circumstances.
•
For your information:
the maximum travel is about 4 mm to each side.
•
Untie the cord from the model. When you give a ‘forward’ command, the boat
should now travel in a straight line forward. With only one VSP operating, the
model will always tend to turn when reversing. However, for the setting-up stage
only forward running is relevant.
•
Once you have completed the set-up procedure for one VSP, disconnect its motor
from the speed controller and connect the other VSP to the controller.
•
At this point the same adjustments have to be carried out on the other VSP.
•
Once you have completed the settings on the second VSP, disconnect it from the
speed controller.
•
Now connect both VSPs to the controller, and carry out a test-run with the boat.
•
The model should run straight in the forward and reverse directions.
•
Now set the maximum motor speed: the rotational speed of the propeller wheel
should be about 457 rpm, which corresponds to a motor speed of N
nom
: 6000 rpm.
This is the same speed as the full-size power plants.
•
On a 12 V supply this rotational speed corresponds to a speed controller setting of
about 52% (Graupner RC system)
•
Maximum speed is available at 8800 rpm. Note that motor speeds higher than this
may damage the VSPs.
•
Special manoeuvres such as tight turns, rotating on the spot and traversing are
certainly possible with this model, but they do require practice. You must use both
dual-axis sticks to control the boat.
•
The stick positions are shown in the diagram. Note that any movement of the
transmitter stick causes the VSP’s control lever to move in the opposite direction.
•
TIP:
the best method of steering large, broad turns is to allow one VSP to run
forwards, and steer with the other. Tight turns are best initiated using both VSPs.
•
When traversing, keep one stick motionless and control the model with the other.
Oil the linkage balls in the ball-links at regular intervals, but take care that no oil runs
through the guide sleeve into the propeller wheel. The plain bearing can be lubricated
lightly with gearbox grease or high-viscosity oil: apply a little grease between the
guide sleeve and the control lever of the VSP.
Important:
do not use mineral oil.
It will take you a lot of practice and many runs before you completely master the
model’s manoeuvring capabilities.
All of us in the Graupner team hope you have loads of fun running your Voith
Schneider VELOX escort tug.
