Maintenance - Traxxas BLAST Bedienungsanleitung

5. Check the wiring for any frayed wires or loose connections.
6. Check the tightness of the set screws in the collars on the steering linkages
and in the universal joint yokes (connecting the outdrive to the driveshaft
and the driveshaft to the motor). Threadlocking compound can be applied
to these screws to prevent them from loosening.
7. Check the mounting of the receiver and servos.
8. Check the rubber driveshaft seal for cuts and tears. Do not attempt to run
the Blast if this seal is damaged.
9. Check the tightness of the propeller. Hold the u-joint and turn the
propeller clockwise until it's fingertight. Visually inspect the propeller for
nicks, dings and warpage. Replace if damaged.
10. Check the operation of the radio system, especially the condition of the
batteries.
11. Visually inspect the hull for any cracks, damage or possible leaks.
12. Check for deterioration of the rubber band that holds the top hatch.
13. Before operating the Blast,
make certain the water pickup
(A) and the exit tube (B) are
clear of debris and are properly
connected. Otherwise, motor
overheating may occur.
After Running Your Blast
1. Spray all the bearings, drivetrain,
and fasteners with WD-40® or similar water displacing light oil.
2. Let the boat stand or blow it off with compressed air.
Removing the hatch and placing the boat in a warm sunny
spot will help with drying.
3. As a precautionary step, remove the sealed receiver box cover. While
unlikely, humidity or tiny amounts of moisture or condensation may
enter the receiver box during running. This can cause long-term
problems with the sensitive electronics in the receiver. Removing the
receiver box cover during storage allows the air inside to dry. This step
can improve the long-term reliability of the receiver. It is not necessary
to remove the receiver or unplug any of the wires.
Receiver Box: Maintaining a Watertight Seal
Removing and Installing Radio Gear
The unique design of the receiver box allows the removal and installation
of the receiver without losing the ability to maintain a watertight seal in
the box. The patented wire clamp feature gives you the ability to also
install aftermarket radio systems and maintain the watertight features of
the receiver box.
Removing the Receiver
1. To remove the cover, remove the two 3x10mm button-head
cap screws.
2. To remove the receiver from the box, simply lift it out and set to the
side. The antenna wire is still inside the clamp area and cannot be
removed yet.
3. Remove the wire clamp by removing the two 2.5x8mm cap screws.
4. Unplug the servo and ESC cables from
the receiver and remove the receiver.
Receiver Installation
1. Always install the wires into the receiver
box before installing the receiver.
2. Install the antenna wire and the servo
cables into the receiver box.
3. Arrange the wires neatly using the wire
guides in the receiver box. The excess
wire will be bundled inside the receiver
box. Label which wire is for which channel.
4. Apply a small bead of silicone grease
(Traxxas part #1647) to the wire clamp.
5. Install the wire clamp and tighten the two
2.5x8mm cap screws securely.
6. Install the receiver into the
box and plug the wires into
the receiver.
7. Make sure the O-ring is properly
seated into the groove in the receiver
box so that the cover will not pinch it
or damage it in any way.

8. Install the cover and tighten the two 3x10mm button-head cap screws
securely.
9. Inspect the cover to make sure that the O-ring seal is not visible.
Tuning Adjustments
Adjusting the Trim Angle
The outdrive strut on the Blast will
allow you to adjust the trim angle of
the propeller. The trim angle changes
how high the bow of the boat rides
out of the water. Setting the trim angle
correctly will provide the maximum
speed and efficiency from the Blast.
As the outdrive is trimmed up, the
bow (front) of the boat will ride higher
causing the boat to run slightly faster; however, it will be more unstable in
the wind. Do not trim the outdrive up on windy days or when running in
choppy water. If the trim is set to high, the bow will bounce up and down
("porpoise"), and the propeller may begin to cavitate. As the outdrive is
trimmed down, the bow of the boat is lowered, increasing the wetted
surface of the boat. This will slow the Blast slightly, but stability and
control will be improved. Experiment
with this adjustment to find out what
works best for your particular conditions.
Adjusting the Outdrive Shaft End Play
There should be a slight amount of shaft
end play in the outdrive housing. To
adjust the end play, loosen the set screw
on the U-joint yoke (see image). Pull the
propeller shaft until there is no more
than 1mm of distance at "arrow 2" in the
drawing. Retighten the set screw.
Boat Retrieval
DANGER! DO NOT SWIM OR WADE INTO THE WATER TO RETRIEVE A BOAT.
If your Blast accidentally flips over and fills with water, it is equipped with
foam flotation to help prevent it from sinking. If you have chosen your
launch sight carefully (downwind), your model will probably drift back to
you on its own. If there is no wind, you will need a tennis ball and a length
of string. Tie the tennis ball securely to one end of the string and then
throw the ball over the drifting boat. Pull the ball in and try to entangle
the boat in the string. Pull the boat back slowly to shore. If only the bow
of the boat remains visible, try using a fishing lure with many hooks and a
fishing pole. Try to snag the lip of the upper deck or drive mechanism with
the hooks.

Maintenance

• Keep the Blast clean of accumulated dirt and oil.
• Re-oil the motor bushings before each day of running. Use an oil made
for electric motors such as 3-in-1 Oil.
• Periodically re-oil the bushing in the outdrive housing and the driveshaft
tube. The oil hole for the driveshaft tube is located underneath the
sealed receiver box.
Storage
Drain all water out of the Blast and thoroughly dry it before storage. Store
the Blast with the hatch cover removed so that any remaining moisture
can to evaporate.
Painting the Hull
If you wish to paint your hull some other color besides the factory white,
choose your paint with caution. Only use paint made for plastic models
(available from your hobby dealer). Test the paint on an inconspicuous
and non-critical area before painting the entire boat. The paint on the
bottom must be smooth to prevent a loss of performance.
Battery iD
Your model's included battery pack is equipped with Traxxas Battery iD.
This exclusive feature allows Traxxas battery chargers (sold separately) to
automatically recognize connected battery packs and optimize the charge
settings for the battery. This eliminates the need to fumble with charger
settings and menus for the easiest and safest charging solution possible.
