MAINTAINING YOUR MODEL
Your model requires regular maintenance for top performance.
The following procedures should be taken very seriously.
Form the
habit of visually inspecting the mechanical integrity of the model
before and after each run.
Inspect the model for obvious damage or wear:
• Normally, some water will accumulate inside the boat. There
are drain holes in the rear of the boat. With the hatch removed,
turn the boat upside down and angle it so that the water will
drain from the holes. Empty any standing water out of the boat
between runs. Pour any water out the side or back of the boat.
• Check the wiring for any frayed wires or loose connections.
• Check the tightness of the set screws in the propeller drive dog.
Thread-locking compound can be applied to these screws to
prevent them from loosening.
• Check the mounting of the receiver and servo.
• Check the tightness of the propeller. Visually inspect the prop for
nicks, dings, and warping. Replace if any damage is noticed.
• Check the operation of the radio system, especially the condition
of the batteries.
• Visually inspect the hull for any cracks, damage, or possible leaks.
• Thoroughly dry the model before you store it. Store the model with
the hatch removed so that any remaining moisture will evaporate.
After each running session:
• Make certain the motor is completely dry, particularly the bearings.
• Lubricate the motor bearings with light oil.
• The flex cable should be removed and have the included
lubricant applied after every three runs (pairs of battery packs) or
15 minutes, whichever comes first.
Note:
A loud “shrieking” noise coming from the boat could
indicate a dry flex cable. Power users (driving at constant, full-
speed operation) will need to do the maintenance more often. If
the flex cable is not lubricated regularly, increased friction and heat
will damage the stuffing tube and it will have to be replaced.
• Release the flex cable from the motor coupler as explained on
page 26, and remove the flex cable by pulling the propeller away
from the drive strut. While the flex cable is removed from the
model, dry and generously apply the included lubricant. Reinstall
the flex cable by reversing the removal steps. Wipe away excess
lubricant.
• Keep all of the screws in the drive system tight.
• Disconnect and remove the batteries from the model and
transmitter.
Centering your Servo
Whenever your radio system has been removed for service or
cleaning, the steering servo must be re-centered prior to installing
the radio system in the model.
1. If the radio system is already installed in the boat, disconnect
the servo horn from the servo.
2. Connect the steering servo to channel 1 on your receiver and
the electronic speed control to channel 2.
3. Place fresh “AA” batteries in the transmitter and turn the power
switch on.
4. Turn off TSM (see page 17).
5. Turn the throttle and steering trim adjustments to the
center position.
6. Keep fingers and objects away from the propeller. Connect two
fresh battery packs to the electronic speed control. The servo
will automatically jump to its center position.
7. The servo horn is now ready to be installed.
8. Be careful not to move the servo shaft when installing the
linkages. Readjust the electronic speed control as described in
the previous section.
Always wear eye protection
when using compressed
air or spray cleaners and
lubricants.
