Maintenance - Traxxas 38104 Bedienungsanleitung

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
If the Blast accidentally flips over and fills with water, it is equipped
with foam flotation to help prevent it from sinking. Traxxas does not
recommend ever trying to swim or wade to retrieve a boat. If you have
chosen your launch sight carefully (downwind), the Blast 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; 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.
