left both contain four letters
STARBOARD: This is the right side of the boat when aboard
and facing the front (bow)
HULL: The body of the boat
DECK: The top of the boat
RUDDER: The hinged vertical plate mounted at the stern that
controls steering
Decals have been provided for your Hammer. Simply peel
and stick! See the photos on the box for decal placement.
TRANSMITTER ASSEMBLY
Important Note: The transmitter is not water resistant and
should never come in contact with water.
❏1. Remove the transmitter antenna from the parts bag and
screw it into the top of the transmitter. To ensure that the
antenna is attached, lightly pull on the base of the antenna. If
it slides out, it is not installed properly.
❏2.Slide off the battery door on the bottom of the transmitter.
Install 8 fresh “AA” batteries into the bottom of the transmitter
in the configuration molded into the battery holder. Re-install
the battery door onto the bottom of the transmitter.
❏3. Turn the transmitter “ON” using the switch on the front.
The red LED light next to the on/off switch should light up. If
the LED does not light up, turn the transmitter off and check to
make sure that the batteries are installed properly. If you see a
flashing LED, the batteries are low and need to be replaced.
BATTERY PACK INSTALLATION
IMPORTANT! Never leave a charger and battery pack
unattended while charging. Use only the recommended
battery pack and an appropriate charger. Do not attempt to
charge the battery while it is installed in the Hammer.
❏4. Remove the body clip at the rear of the top deck and
carefully remove the hatch.

❏ 5.Peel the backing off of the supplied hook & loop material
and apply the “loop” side to your 6-cell battery pack. Place a
fully charged battery pack onto the battery tray as shown.
❏6.Plug the battery pack into the boat’s ESC (Electronic Speed
Control) battery connector. Do not force them together; they
are designed to fit together only one way.
CHECK THE RADIO SYSTEM:
❏7.Turn the power “ON” to the transmitter and receiver (in
that order).
❏8. If the boat’s propeller begins to spin once power is turned
“ON”, make sure your your transmitter is “ON” and simply
rotate the throttle trim knob located atop the transmitter until
it stops.
❏9. Standing behind the boat with the radio system turned
“ON”, rotate the steering wheel of your transmitter to the left.
The back of the rudder should move towards the left. Rotate
the steering wheel of your transmitter to the right. The back of
the rudder should move towards the right. If this is not the
case, simply move the transmitter’s steering servo reverse
switch to the other position.
❏10. Squeeze the trigger on the transmitter; this should
activate the propeller in a counter-clockwise motion. If this is
not the case, try moving the throttle servo reversing switch to
the other position. Pushing the trigger forward will activate
the propeller in a clockwise rotation; this is the “REVERSE”
feature and it can be used to either back out of precarious
water or slow the boat down quickly.
❏11. The D/R knob located atop the transmitter is the
steering rate adjustment. Turning the knob to the right
increases the total movement of the rudder while turning it to
the left decreases the rudder movement.

❏12. Replace the hatch as shown, by first placing the hole at
the front of the hatch cover over the pin at the front of the
hatch opening. Replace the body clip. The boat is powered
“UP” and ready to go!
❏13. After running, turn the power “OFF” to your boat’s
receiver and then transmitter (always, in that order).
PLEASE READ BEFORE Running the Hammer:
• NEVER attempt to swim after a stalled or capsized boat!
Wait patiently for the wind currents to return the boat to
shore or use a tennis ball attached to the end of a fishing
rod to retrieve a stalled or capsized boat.
• It is dangerous to operate any R/C vehicle at any time that
there is not sufficient light.
• R/C models produce vibrations which will cause screws,
nuts, bolts, etc, on your model to become loose over
time. It is important to make sure that all hardware is
secure before operating your model.
• The edges of the propeller are very sharp and can cut your
fingers if you are not careful. At no time should you ever
attempt to stop the prop with your hand. In the event that
weeds become entangled in the propeller, turn the
Hammer’s power “OFF” before attempting to remove them.
• CAUTION: Your Hammer may take on small amounts of
water, especially when running in rough water due to
high winds or when making tight turns. Keep a roll of
paper towels handy and dry out the hull interior after
every run.
• Total run time of the Hammer is approximately 6-10
minutes (assuming you begin with a fully charged battery
pack). When you notice a decrease in power or sluggish
steering response, it means the battery pack is nearly
drained and it’s time to head for shore. As soon as the
boat reaches shore, turn off the power to the boat’s
receiver and transmitter (in that order).
• CAUTION: The motor may be hot! Allow it to cool for a
few minutes before attempting to remove the battery pack.
• After running, store your Hammer with the hatches opened
to allow the interior to dry out completely. If you fail to do
this, it may result in corrosion of the electronic components.
• IMPORTANT: If, for whatever reason your boat takes on a
large amount of water causing the radio equipment to get
wet, you must do the following immediately: Remove the
battery pack and radio equipment from the boat. Allow the
components to air dry completely before reassembling.
Reinstall the components and check for proper operation
before running the boat in water.
Launch Procedure:
1. Turn the power “ON” to the transmitter and receiver (in
that order).
2. Gently place the boat in water that is at least 8" deep and
free of obstacles (weeds, rocks, sticks, ducks, muskrats, etc.).
3. Slowly advance the throttle to full speed and note if the
boat has a tendency to turn right or left. Adjust the steering
trim knob on your transmitter until the boat runs in a straight
line when the steering wheel is at neutral.
4. When finished running, be sure to turn the power “OFF” to
your boat and transmitter (in that order).
The Waiting Game
If your Hammer should happen to stall, wind and/or water
currents will slowly carry it to shore. The bad news is that the
boat could be carried to the opposite shore. When surveying
areas to run your boat, keep variables in mind such as wind
direction, size of the lake, strength of river currents, etc.
Above all, NEVER attempt to swim after a stalled boat.
HELPFUL TIP:
Use a fishing rod with at least 12lb. line and a tennis ball tied
to the end to retrieve a stalled boat.
GOOD LUCK AND GREAT BOATING!
RUNNING THE HAMMER
5
Although it is very enjoyable to go out and run the Hammer by
yourself, we think the real fun and excitement is experienced
when you get involved in RACING!
Racing does not have to be an organized and sanctioned
competition to be fun. In fact, small, informal races can be
very exciting without the stress that comes with formal events.
Here are some suggestions for setting up a simple race course
for boats:
• Make 2 to 4 simple and inexpensive “marker buoys” with
empty milk jugs, string and heavy objects for anchors, similar
to the above sketch.
• For “drag racing” place the buoys similar to the above sketch.
•For “oval racing” place the buoys similar to the above
sketch. NOTE: The above patterns are not based on any sort
of official standards; therefore, you may set up race courses
any way you desire, using your imagination to make the races
more interesting. Usually the smaller courses will provide
more action and excitement.
The length of the races can be determined by a set number of
laps around the buoys (for example, the first boat to complete
5 laps is the winner); or by time (for example, whoever is
leading at the end of two minutes is the winner).
