Thank you for your purchase of the TTR Seawolf submarine. The Seawolf submarine is the 1st
underwater R/C model by TTR. Equipped with high technology operating system in the inner hull
tube, covered by bright orange color outer hull, the Seawolf will let you enjoy the underwater
world.
With static diving system, operating the Seawolf submarine is just like the real thing. The system
equip with a ballast tank that comes with a pump unit. Start the pump to induct the water into the
ballast tank. Control the amount of water into the ballast tank, the Seawolf submarine can dive
from the surface and stay underwater in static. Using the propulsion power unit and full elevator
and rudder control, you can drive the Seawolf submarine gracefully into water. Install a digital
camera and you can watch the amazing underwater scenes.
Equipped with an auto protecting system, if the system detects low battery power, low transmis-
sion signal or leakage, the pump will start automatically to flood the water out of the ballast tank
to make the Seawolf submarine float back to the surface.
TTRobotix Seawolf submarine will take you to enjoy the mystery world under the water!

One 4S LiFe battery is included in the kit to supply the requiring power for all the electric
equipment and drive system. DO NOT leave the charger unattended, DO NOT operate
the charging process in flammable environment.
1. This radio control submarine is not a toy. If not properly assembled and operated, it is
capable of causing property damage. TTRobotix and it’s distributor have no control
over damage resulting from shipping, improper construction, or improper usage.
2. You must choose the suitable and safety area to operate the submarine. It is danger-
ous to drop the Seawolf into water.

1) The radio show in the drawing is similar to MODE 2 of RC airplanes: throttle is at the left stick and elevator is at
the right one. However, the stick radio easily allows to shift to Mode 1. Open the inner hull and exchange the
servo connectors at the receiver.
2) Due to it’s more difficult for the RF signal through the water(especially in sea water). The control distance is
much shorter than the radio system operating on the surface. Base on our experience, maximum controllable
depth for 40Mhz RF radio system is about 5M.

On the main control PCB unit, there are 3 LED lights are designed to show the current status of the Seawolf
submarine. You can observe the light and refer to the following chart to get the light information.
AUTO PROTECTING SYSTEM
Combined with a auto protecting system on the main PCB control board, if the system detects low battery power,
low transmission signal, leakage(water inside hull), then the roll pump will auto start to flood the water out of the
ballast tank to make the submarine float back to the surface. At the same time, the Red LED light will flash.
PUMP WITH BALLAST FOR THE STATIC DIVING SYSTEM
05
Light Sign Light SignSeawolf Status Seawolf Status
Base on the Archimedes principle—principle that states a body immersed in a fluid is buoyed up by a force equal
to the weight of the displaced fluid. The principle applies to both floating and submerged bodies.
So base on this principle, equipped with a roll pump with ballast tank device in the inner hull, through the pump
operating system to draw or drain the water into or out of the ballast tank to change the weight of the submarine.
With suitable design of the volume and weight, then it is easy to operate the Seawolf diving or floating and even
static stay under the water. So we call this the static diving system just like the real submarine.
The buoyancy of an object depends, therefore, only upon two factors: the object's volume, and the density of
the surrounding fluid. So when you choose the diffierence water(with diffierence density) to play, you have to read-
just the weight unit to make the submarine can be diving and floating smoothly and quickly. Normally, it need take
about 50 seconds from floating to diving.

06
Switch on the transmitter. Check again TX battery status.
Switch on the receiver (main switch). Check no interference from any other RC transmitter
If the submarine doesn’t switch on, check the fuse and replace if necessary.
Check that the front hood is perfectly installed. If it isn’t, any hit during the launch will cause it to fall down
into the water. It will sink, being heavier that the water. Therefore, pay much attention.
If the camera is not used, check that the cap of the cable connector is tightened. If the camera is used,
see “Camera operation” paragraph.
Start the pump and empty the bag (left stick to left), until the bag is totally emptied. This will be shown by
the changed noise and the absence of air coming out from the water intake.
The main power switch is located at the bottom of the front
flange. From the bottom view, the left switch is to control the
main battery power for all the electric devices. The right switch
is unused.
For fresh water use only.
Check if there is no water is inside the hull. If water is found inside the hull, the submarine shouldn’t be
used until you discover the cause of the problem and solve it.
Close the front cap and tighten the nuts (sequence: opposite nuts). After locking, the front O-Ring should
appear uniformly flattened against the cap.
Switch on the transmitter and check TX battery status.
Switch on the submarine and check the following functions:
Check throttle: move left stick up/down and verify that full forward and reverse speed is reached. In
centre position (idle) the propeller should not move. Correct TX trim if necessary
Check pump: move left stick right and left and verify that the pump starts running and inflates or empties
the ballast. You may hear the noise of the motor and also feel the pump action by placing a finger at the
water intake.
Check dive planes (right stick up/down). Verify that stick neutral position corresponds to horizontal dive
planes. Trim if necessary.
Check rudder (right stick left right). Verify that stick neutral position corresponds to straight rudder. Trim if
necessary.
Switch off RX and TX respectively.
NOTE: Pump action is on-off and it’s normal that it is not proportional. However, be sure that the
centre idle position of the stick is equally far from left and right working position.
Trim if necessary.
NOTE: If the fuse is burnt again, then should be a short circuit inside. Don’t use the model.
Open it and search for any electrical problem)

Start piloting your Seawolf.
Find a good launch location, with the possibility to stand stable with no risk of falling into the water. The water
surface should be easily reachable and must not be too low. Becareful with tide.
Insert the handle into the holes of the external hull. Be sure that the hooks are connected to the metal rod of
the inner hull and not only to the outer plastics .
Lift the sub and gently place it into the water.
Wait until the front hood and the rear cone are totally full of water. These are free-flood compartments and it’s
normal they become totally full of water, no large air bubble should remain inside them.
At this point, disconnect the handle.
07
NOTE: Pay attention not to let the handle fall into the water, it will sink!

All the controls are described above.
Rudder and throttle functions are similar to other R/C models.
This submarine is capable to perform both static and dynamic dive.
For a full static dive, keep the motor idle and start the pump flooding the bag. You will see the waterline at the
turret become higher and higher until the entire submarine will be submerged and will go down vertically to
the bottom. The opposite command will cause the pump to empty the ballast bag and the submarine will raise
to the surface.
Dynamic dive is possible thanks to the speed of the boat and the action of the dive planes. The ideal situation
is reached when only the top ring of the turret is out of the water: at this point, start the motor full forward and
set the dive planes to the “down” position: the submarine will dive and you will have dynamic control of the
depth by operating the dive planes.
Pay attention to any collision. If the submarine is running in a swimming pool or any other place with hard
vertical walls, avoid any hit with these hard structures. The front elerator and hood might be damaged or even
broken.
Also, be aware to avoid algae, leafs or any other seaweed that may jam the propeller. If leafs or other are
tangled around the propeller shaft, its efficiency will be greatly reduced and the stress on the motor will be
much higher. This situation should be avoided in order not to have critical damages on the propulsion system.
If the submarine raises to the surface on its own, it’s possible that some safety function has switched on. Take
the submarine out of water and check the alarm code from the LED indicator on the PCB.
If the submarine raises to surface because of low battery, you will discover much lower motor power and no
capability of diving. At this point, recover immediately the sub before the battery is completely empty (Please
remember that the receiver is BEC-equipped and the power source is the same also for the electronics!).
08
Remove the outer hull panels and clean every part.
Before storing the submarine for a long time keep the inner hull open, disconnet the battery and fuse.
Check the pressure sensor (try to over fill the ballast bag).
Check the fail safe system (switch off the RC transmitter and see if the protection system activates).
Check the low battery safety system.
Check the integrity of inner hull. No cracks on inner tube.
Check there is no leakage from the inner linkages and tubing.
Check the dive planes and rudder operating angles. Adjust control rods and TX trims if necessary.
Check the O-Ring status and correct tightening.
Check operation of the switches and of all the other water proof exits. Devices must be tightened but must
retain a smooth movement.

CHARGER CONNECTION STEPS
Remove the fuse. Keep it in a safe place.
Connect the charger to the AC power source.
Connect the charging cables and balance board to the charger as shown.
Connect Red Cable to Red Jack on the Seawolf.
Connect BLACK Cable to BLACK Jack on the Seawolf.
Connect the balance cable of the battery to the balance board.
The charger should begin to charge the battery. When charge is done, disconnect the cables in reverse order.
Tight the front panel screws diagonally in order to seal the hull properly with even pressure. The front O ring
should appear uniformly flattened against the cap.or the electronics!).
