‘93’ Series RTR Brushless EP Racing Boat
Note: The ‘Offshore Warrior’, ‘Offshore Sea Rider’ and ‘Offshore Sea Drifter’ will also be referred to as
‘Warrior’, ‘Sea Rider and ‘Sea Drifter’ in these instructions, as well as “93’ series models’.
IMPORTANT
Before using this ‘93’ series model and its radio control system, and to ensure the safety of yourself and
others, it is very important that you read these instructions thoroughly and understand them.
‘93’ series models are capable of speeds in excess of 50km/h! Care should be taken to avoid the
possibility of injury and/or property damage.
‘93’ series models are designed for use in fresh water only. They are not designed for use in salt water!
‘93’ series models are not intended for persons under 14 years of age, unless closely supervised by an
adult.
ASSEMBLING THE BOAT STAND
Assemble the included boat stand by slotting the
pieces together as shown (Warrior stand shown for
reference). Apply cyanoacrylate glue or 2-part epoxy
to secure the joints and allow the glue to completely
set before placing your ‘93’ series model on it.
INSTALLING THE BATTERY PACK IN '93' SERIES MODELS
(Model should be placed on its supplied boat stand with the transmitter switched 'ON', having previously
read and understood the radio control instructions)
1) Remove the '93' series model’s upper deck by unscrewing the knurled knob at its rear section.
2) Remove the clear plastic cover.
3) Insert the battery pack into the hull as shown below and secure with the hook and loop strap inside
the hull.
4) Attach the LiPo battery pack’s connector to the matching connector in the model. Do not force them
together - they only attach one way!
5) Replace the clear plastic cover (seal with the provided waterproof tape) and re-position the upper
deck, securing with the knurled knob.
Attention: Before replacing the '93' series model's clear plastic cover and upper deck, check to ensure
that the water-cooling tubing that connects to the motor is not obstructed or kinked, as this can cause
the motor and speed controller to overheat and potentially burn out.
Note 1: ‘93’ series models will typically run for around 8 minutes on a fully charged LiPo battery pack,
although this will vary depending on the type and capacity of LiPo pack you choose. As soon as you
notice a drop off in speed you should bring the model back to shore or control may be lost.
Note 2: If you want to run your ‘93’ series model for extended periods, you can purchase additional LiPo
battery packs. However, continuous running of the model will generate high heat levels, which will lead
to premature wear of the brushless motor. Once your LiPo battery pack is exhausted, we recommend
that you let the model cool down for 5~10 minutes before installing a fresh one.

WATERPROOFING TIPS
You should take steps to ensure that your ‘93’ series model and its radio control equipment are adequately
protected against the possibility of water damage. We recommend that you place your model’s receiver
inside a rubber bag (balloon) and tie the end off with a cable tie or similar.
Use the clear plastic sheet and waterproofing tape provided to seal the hull as shown after you have
connected the LiPo battery pack, before placing your ‘93’ series model on the water.
Ensure the propeller’s flexible shaft is properly lubricated
(see below) as this too will reduce the possibility of water
entering the hull during operation.
LUBRICATING THE PROPELLER SHAFT
Lubricating the '93' series model's flexible propeller shaft is vital to its
smooth operation and lifespan. The lubricant also acts as a water seal,
helping to prevent water from entering the hull via the propeller tube.
It is recommended that you lubricate the propeller shaft and tube every
2~3 hours.
1) Use the 2.0mm Allen key provided to loosen the grub screws that
secure the flexible shaft to the coupler, then slide the flexible shaft out
of the propeller tube.
2) Lubricate the flexible shaft and propeller tube with waterproof marine
grease and reinstall the flexible shaft, re-tightening the grub screws in
the coupler.
Note: Never apply grease to the '93' series model's brushless motor.
HOW TO CONTROL/OPERATE YOUR ‘93’ SERIES BOAT
1) Forward Throttle Trigger
Your '93' series boat can be driven forward by pulling the throttle trigger.
Release the trigger and the model will stop.
2) Left/Right Steering Wheel
2
The steering wheel controls the '93' series model's left and right movement.
Turn the wheel to the left to steer to the left. Turn the wheel to the right to
steer to the right. Release the wheel to go straight.
Racing Tip: '93' series models are designed for racing, and will be less
responsive to steering inputs at high speed. Decrease your speed to allow
tighter turning.
Note: For full details of the operation of your transmitter, refer to the
separately included radio control instruction manual.

TURN FINS
The Warrior and Sea Rider feature adjustable turn fins to aid in turning. These can
be adjusted using the included Allen key. The optimum angle of adjustment is 45
degrees to the hull.
GETTING READY TO USE YOUR '93' SERIES MODEL
(Model should be placed on its supplied boat stand)
1) Check that the turn fins are adjusted correctly (for
Warrior/Sea Rider).
2) Switch ‘ON’ the transmitter. Check that the transmitter’s
power LED glows green.
3) Plug the LiPo battery into the ESC - you will hear three
continuous audible beeps.
4) Pull the throttle trigger on the transmitter - the boat’s
propeller should turn anticlockwise.
5) Check that the rudder responds correctly to transmitter
inputs.
6) Seal the clear plastic cover with the included waterproof
tape, taking care to ensure the water-cooling tubing is not
kinked.
7) Fit the upper deck and secure with the included fixing
knob.
AFTER USE
1) When you have finished using your '93' series model, you should first switch ‘OFF’ the model
(disconnect the LiPo battery pack), then switch ‘OFF’ your transmitter.
2) Remove all batteries from the transmitter and model.
3) Leave the '93' series model’s upper deck and clear plastic cover off to allow moisture to evaporate. If
fitted, also temporarily remove the receiver from its rubber bag. Ideally, place the model in this way in a
warm and dry place, like an airing cupboard, until you are sure it is dry and then store it away.
4) Periodically grease the '93' series model’s propeller shaft and tube as this will reduce wear and also
help prevent water from entering the hull.

IF THE ‘93’ SERIES MODEL DOES NOT RUN IN A STRAIGHT LINE
Note: These adjustments should be carried out in conjunction with the separately included radio control
instructions.
If your '93' series model does not run in a straight line when not being steered, you can adjust it by using
the steering trim located on the transmitter.
1) Run your '93' series model on calm water when adjusting the steering. If your model runs to the right
when not being steered, adjust the trim control a little to the left, re-centre the model and see if this has
corrected the problem. Keep making small adjustments in this way until the model runs straight.
Adjust the trim control to the right to correct if your model steers to the left without being steered in the
same way as detailed above.
2) You can also adjust the '93' series model's throttle response using the Throttle Trim, located on the
transmitter.
If, when you connect the LiPo battery pack, the '93' series model’s propeller starts turning without
transmitter input, you can adjust it back to neutral (stopped) moving the Throttle Trim control to the left.
You should adjust this trim so that the propeller starts to turn as soon as you depress the transmitter’s
trigger, but the propeller stops turning immediately the trigger is released.
CIRCUIT & COOLING SYSTEM DIAGRAM FOR '93' SERIES BOATS
Each '93' series model is supplied from the factory with radio and cooling systems already set up.
However, if you have cause to maintenance, repair or replace parts in your model in the future, this chart
can be of help when it comes time to re-install/re-connect everything.
ESC (ELECTRONIC SPEED CONTROLLER) CALIBRATION & SPECIFICATION
Calibration:
1) First, ensure the brushless motor and receiver are properly connected to the ESC.
2) Next, pull and hold the transmitter's throttle trigger at maximum, then switch 'ON' the transmitter.
