Install Propeller, Rudder and Fins
1. Align the propeller with the drive dog on the flex shaft
and install the propeller using the included locknut.
Tip: Remove the left and right trim tabs from the boat to
install the vertical fins more easily.
2. Install the left and right turn fins using two M3x8 cap
screws for each turn fin (total of four screws). Adjust the
vertical fins for the desired stability.
3. Install the left and right trim tabs using two M3x10 cap
screws for each trim tab (total of four screws).
4. Attach the rudder to the rudder pivot plate using one
M3x15 cap screw and one 3mm locknut (top hole).
5. Install one M3x10 Phillips head screw in the rudder
pivot plate (bottom hole). The Phillips head screw also
acts as a shear pin for the break-away rudder.
7. When the boat is moving forward, ensure water flows
out of the coolant outlet on the side of the boat. If water
does not flow out of this outlet, remove any blockage
from the rudder inlet and coolant system or the motor and
ESC (electronic speed control) may overheat.
Ensure the trim tab panels are flush with the bottom of
the boat. You may desire to bend the trim tabs for wind
and water conditions. To adjust the angle of the trim tabs,
use a large pair of pliers to bend the tabs. This must be
done carefully so that you do not damage the hull.
CAUTION: Always use caution when installing the
fins or handling your boat, the turn fins are sharp. Failure
to do so could cause personal injury
6. Connect the cooling line to the top of the rudder.

Antenna Tube Installation
1. Carefully feed the end of the longer receiver
antenna through the grommet inside the hull.
2. Pull the antenna wire out of the grommet
towards the outside of the boat, then slide the
antenna through the antenna tube.
3. Insert the tube into the grommet, then
fit the cap onto the tube.
Arrange the shorter antenna in the hull at a right or near
90 degree angle to the antenna in the tube. Attach the
antenna inside the hull, away from all electrical wiring and
components using clear tape.
The antennas must be installed correctly above the boat's
water line to get the best reception of your transmitter's
signal.
4. Apply clear tape to the antenna, grommet
and hull in the boat to keep the antenna
from moving.

Battery Safety Precautions
• When using a Li-Po battery, always ensure the
Battery Chemistry Switch is in the ON position.
• Always disconnect a battery from the ESC when
not in use.
• Never discharge a Li-Po battery below 3V per cell.
• Avoid continually operating to LVC, as this could
result in damage to the battery.
Installing the Battery Pack(s)
2. Remove the radio box cover. Where needed, install
the included self-adhesive hook strips on your battery
pack(s).
5. Install the cover over the pack(s) and tighten the wing
nut on the screw to hold the pack(s). Loosen the wing
nut and move the pack(s) forward or back to adjust
the center of gravity for your boat. Move the pack(s)
toward the bow so the bow rides lower in the water.
Move the pack(s) away from the bow so that the bow
rides higher in the water.
3. Remove the wing nut and cover from the battery
compartment.
6. Connect the battery pack(s) to the ESC power
connectors.
4. Install the included hook and loop tape on the battery
packs. Install the batteries on the hook and loop strips
in the compartment, then place the included clear tube
on the screw to prevent the screw from cutting the
packs.
7. Disassemble in reverse order.
1. Turn the latch so that the tab is parallel with the back
of the hull, then lift the hatch up and back from the
hull.

Checking the Radio System
4. Power on the ESC and the boat will beep 5 times.
CAUTION: Always keep all body parts, hair
and dangling or loose items away from the propeller
and fin, as these could become entangled.
NOTICE: Always power on the transmitter before
powering on the ESC. Always power off the ESC
before powering off the transmitter. Never transport
the boat with the battery connected to the ESC.
1. Turn the transmitter throttle and steering trim knobs
to the 10 o’clock position.
2. Power on the transmitter.
5. Ensure the rudder moves to the left when
the steering wheel is turned left.
6. Pull the throttle to full, then return the throttle to
neutral, ensuring the propeller turns counterclockwise.
Brushless boats have an over-rev limit that will not allow
you to hold full throttle when the propeller is not loaded
(out of the water).
If the over-rev limiter becomes engaged, rearm
the ESC by returning the throttle trigger to neutral.
The auto-sensing voltage cutoff will also engage when
the ESC detects low battery charge. If this occurs,
release the throttle and recharge the boat batteries.
3. Connect a fully charged battery to the ESC.

Failsafe
In the unlikely event that the radio link is lost during use,
the receiver will drive the servos to their preprogrammed
failsafe positions (normally no throttle and straight
steering). If the receiver is powered on before powering
on the transmitter, the receiver will enter failsafe mode,
driving the servos to their preset failsafe positions. When
the transmitter is powered on, normal control is resumed.
Failsafe servo positions are set during binding.
Impulse 31

Binding
Binding is the process of programming the receiver of
the control unit to recognize the GUID (Globally Unique
Identifier) code of a single specific transmitter. The DX2E
and MR200 are bound at the factory. If you need to
rebind, follow the instructions below.
4. Release the bind button when the green LED flashes.

receiver.
5. The receiver's LED will turn solid when
the transmitter and receiver are bound.
2. When a battery is connected to the
ESC and the ESC is connected to
the throttle port on the receiver,
power on the ESC switch. An LED on the receiver will
flash rapidly, showing the receiver is in Bind mode.
You must rebind when:
3. Do not touch the throttle or steering controls, as this
sets failsafe settings. The throttle and throttle trim
should always be at the lowest setting during bind
mode. Press and hold the bind button and power on the transmitter. The green LED on the front of the
transmitter will flash within three seconds, indicating
the transmitter is in bind mode.
Testing Your Boat in the Water
1. Carefully place the boat in the water.
2. Operate the boat at slow speeds near the shoreline.
Avoid objects in the water at all times.
3. Once you are comfortable operating the boat at
slow speeds, it is safe to operate the boat farther
from the shore.
4. When the boat is moving forward, ensure water flows
out of the coolant outlet. Remove any blockage from
the rudder inlet and coolant system or the motor and
ESC (electronic speed control) may overheat.
6. Remove the bind plug and store it in
a convenient place.
• Changing receiver types e.g., changing from a DSM®
receiver to a DSM2® or Marine receiver.
• Binding the receiver to a different transmitter.
Important: If you are using too much steering trim
on your transmitter to make the boat steer straight,
mechanically center the rudder. Return the steering
control to neutral, loosen the ball link on the rudder
horn, then turn the linkage threads until the ruder is
centered
5. Bring the boat back to shore when you notice
the boat starting to lose speed.
6. Power off the ESC and disconnect the battery packs.
7. Allow the motor, ESC and battery packs to cool before
charging the batteries or operating the boat again.
NOTICE: Do not turn off the transmitter first
or the receiver may pick up stray signals and
run out of control.
Boating Tips
CAUTION: Always ensure you are operating
this boat a safe distance (15 feet, 5 meters) away
from people and/or other vehicles in the water.
Avoid boating near other watercraft, stationary objects,
waves, wakes and other rapidly moving water, wildlife,
floating debris or overhanging trees. You should also be
careful to avoid boating in areas where there are many
people, such as swimming areas, park waterways or
fishing areas. Consult local laws and ordinances before
choosing a location to pilot your boat.
Maximum speeds are only achieved when the water
conditions are smooth and there is little wind. A sharp
turn, wind or waves can turn over a boat when it is
moving quickly. Always pilot your boat for the wind and
water conditions so that the boat does not turn over.
8
When running your boat for the first time, we
recommend calm wind and water conditions so that
you can learn how the boat responds to your control.
When making turns, decrease the throttle position
in order to decrease speed and probability of flipping
the boat over.
NOTICE: When running at full speed in choppy
waters, the prop may exit and re-enter the water
repeatedly and very quickly, subjecting the propeller
to some stress. Frequent stress may damage
the propeller.
CAUTION: Never retrieve your boat from
the water in extreme temperatures, turbulence
or without supervision.
Impulse 31
Center of Gravity
Moving the batteries to the front or back can significantly
affect the boat's performance.
1. Move the batteries toward the rear of the boat
to raise the front of the hull out of the water for
increased speed.
2. Move the batteries toward the front of the boat for
faster initial acceleration to eliminate oscillation or
bouncing and to increase stability.
Drive Height
Lowering the drive will increase the propeller's ability to
bite at takeoff, but excessive lowering can cause the back
of the boat to feel loose and decrease top end stability.
Raising the drive helps eliminate oscillation or bouncing
and with top end stability, but excessively raising the
drive can reduce top speeds and cause cavitation.
You may also turn the dual rate dial down to reduce
rudder travel in rough water conditions.
If the conditions are questionable, adjust the prop strut
down a bit to reduce the likelihood of having the boat
overturn. The motor mount is slotted to allow you to
move the motor slightly when adjusting the propeller
strut. Loosen the motor mounting screws when
adjusting the propeller strut angle trim and retighten
after adjustment is complete. Use a 3mm hex wrench
and 7mm nut driver to loosen the bolt that attaches
the output to the bracket to adjust the height. Raise or
lower the prop strut. Tighten the bolt when adjustment is
complete.
Motor Care
• Prolong motor life by preventing overheating
conditions. Undue motor wear results from frequent
turns, stops and starts, pushing objects, boating in
rough water or vegetation and boating continuously at
high speed.
• Over-temperature protection is installed on the ESC to
prevent circuit damage, but cannot protect the motor
from pushing against heavy resistance.
When You are Finished
1. Power off the ESC.
2. Disconnect the battery.

3. Power off the transmitter.
4. Remove the battery from
the boat.
Always store the boat open (without
the hatch and innner liner sealed) or
moisture may allow mold and mildew
to grow in the boat.

Maintenance
CAUTION: Always replace the flexshaft when it is
damaged or shows visible wear. Failure to do so could
result in personal injury or property damage.
Lubricating the flexshaft is vital to the life of the
drivetrain. The lubricant also acts as a water seal, keeping
water from entering the hull through the stuffing box.
3. Remove the drive shaft by sliding it out of the stuffing
box. Wipe lubricant and material from the flexshaft.
Lubricate the full length of the flexshaft assembly
up to the drive dog using marine grease (PRB0101
or PRB0100).
4. Apply threadlock to the coupling setscrew.
Threadlock will help prevent the flexshaft
from loosening during use.
Lubricate the flexshaft, propeller shaft and all moving
parts after every 2–3 hours of operation. Always replace
any parts that show visible wear or damage.
1. Loosen the coupling between the motor and
the flexshaft.
5. Carefully reinstall the drive shaft, ensuring that there
is a 1–2mm gap between the prop strut and the drive
dog to allow for flexshaft shrinkage under load.
2. Loosen the setscrew from the flexshaft and remove
the flexshaft from the back of the boat.
NOTICE: Running the boat in saltwater could
cause some parts to corrode. If you run the boat
in saltwater, rinse it thoroughly in fresh water
after each use and lubricate the drive system.
NOTICE: Because of its corrosive effects,
running RC boats in saltwater is at the discretion
of the modeler.
Tip: Use paper or cloth to touch the flexshaft.

Impulse 31
ESC
The included ESC programming card (DYNM3821) allows
you to quickly program your Dynamite® Marine Brushless
ESC control settings.
Programmable Settings
Throttle Reverse: ON or OFF
Cutoff Voltage: High Cutoff or Low Cutoff
High Cutoff: The Ni-MH Cutoff voltage is .9 volts per
cell and the Li-Po Cutoff is 3.3 volts per cell. High Cutoff
allows ample power in reserve after Cutoff for returning
the boat to shore.
Low Cutoff: The Ni-MH Cutoff voltage is .7 volts per
cell and the Li-Po Cutoff is 3.0 volts per cell. Low Cutoff
allows longer runtimes, but leaves less power in reserve
after Cutoff for returning the boat to shore.
Cutoff Type: Idle or Slow Down
Idle: When the Cutoff voltage is reached, the ESC will
stop delivering power to the motor.
Slow Down: When the Cutoff voltage is reached, the
ESC will drop to 50% power at full throttle.
To reset, return the throttle to neutral.
Brake: ON or OFF
ON: The boat will stop immediately when the throttle is
returned to neutral.
OFF: The boat will coast to a stop.
Timing: Low Timing or High Timing
Low Timing: For 2-, 4- or 6-pole inrunner motors.
Allows the longest run times.
High Timing: For 6-pole or more inrunner and outrunner
motors.
High timing increases both motor RPM and current
draw (up to 20% increase compared to low timing)
using the same battery pack and prop. Run times will be
signicantly reduced.
Only use High Timing if the temperatures of the
electronic components do not exceed 130°F (54°C) in
Low Timing mode.
Throttle Curve: Linear or Logarithm
Linear: The ESC delivers 60% power at half throttle and
100% power at full throttle.
Logarithm: The ESC delivers 45% power at half throttle
and 80% power at full throttle (recommended for
beginners).
Using the ESC Programming Card
1. Set all programming card setting switches to the
desired positions.
2. Ensure the ESC is powered OFF and disconnected
from a battery.
3. Connect the ESC receiver lead to the ESC port on the
programming card, noting proper polarity.
4. Connect a fully charged battery to the ESC or the
programming card, then power on the ESC.
5. The ESC will beep, indicating that the new
programming has been accepted.

Horizon’s sole obligation and purchaser’s sole and
exclusive remedy shall be that Horizon will, at its option,
either (i) service, or (ii) replace, any Product determined
by Horizon to be defective. Horizon reserves the right
to inspect any and all Product(s) involved in a warranty

OF SUCH DAMAGES. Further, in no event shall the
liability of Horizon exceed the individual price of the

the right to change or modify this warranty at any
time without notice.
