RADIO CHECK
Check the radio manual to familiar with the
adjustment of the throttle activity and the steering
dual rates.
In above figures, squeeze the trigger on the
transmitter; throttle is opened. Conversely, moving
the trigger forward, throttle is closed completely. If
this is not the case, you will need to reverse the
direction of the servo. Check the instruction manual
that came with your radio system for the correct
procedure.
Now you may break-in your outboard marine engine.
Refer to engine manual about the engine break-in
procedure.

the power. However, higher nitro means higher
price and also will decrease the life of engine.
The suggested initial setting:

PERFORMANCE TIPS& RACING
BALANCING THE PROPELLER
To improve performance, balancing the metal
propeller is highly recommend. First remove any
flashing on the propeller then use quality propeller
balancer to do the balancing. It is not necessary to
polish the propeller as it only improve the out-looking.
THRUST ANGLE
The default setting of the thrust angle is in the neutral
position. However, it might be necessary to adjust if
you meet the following situation.
Bow Up-Adjust the thrust angle to negative so it will
Downward the bow.
Bow Down-Adjust the thrust angle to positive so it will
Upward the bow.
PROP DEPTH
The default setting is 3mm from prop shaft to the
bottom line. If user use other engine then you will have
to re-drill the mounting hole for correct depth. Please
refer to Engine Manual to adjust the propeller depth
when cornering to reach peak performance if
necessary.
Submerging-Adjust the angle to positive.
Sliding-Lower the depth will help reducing
By carefully adjusting the prop depth and the thrust
angle you can find more speed and increase the
stability of the boat to suit your driving style.
Different props also change the characteristics of the
boat. Please take your time with this set-up!
RUNNING THE BANDIT
LAUNCH PROCEDURE
1.Refer to radio manual and always transmitter on first
receiver last.
2.Start the engine and (Refer to Engine Manual to
start the engine). always stay clear of spinning
propeller.
3. Place the Bandit carefully in the water and make
sure that there are no obstacles in the way like rocks
and weeds.
4. When finished running, stop the engine then
receiver off first transmitter off last.
MAINTENANCE
RADIO BOX
Check Radio box immediately once flipping is occurred.
Always keep radio box open after running to absorb
any moisture.
Always place the receiver and battery in the balloon.
Always remove receive and battery from balloon after
running.
Water resistant tape is good for sealing the radio box
cover to the radio box.
Use “Hair Gun” or any way to dry the radio box,
connectors, switch and all the components in the box.
HULL
1.Always clean the hull after each run special at the
areas where has fuel or exhaust residue.
2.Pull the rubber plug located on the transom every
post-run and drain out any water that may have found
inside the hull. Insert the plug before running and
check its tightness.
3.Always unplug the rubber plug once you would store
for a period of time, this is to keep the moisture out of
the hull.
ENGINE
Pump out all fuel after running. Then remove the glow
plug and drop some After-Run-Oil or spray WD-40 in
the carburetor (Full Throttle) then using starter to
rotate the cone and make sure the lubricating oil is in.
RACING
It is always exciting to race with other boats. Be aware
of following suggestions before you go race with other
boats.
1.Fine tune your engine and boat. Make sure all
screws are fasten firmly.
2.Aware of the environments and racing course.
3.Aware of the rough water created by other boats.
4.Keep distance to other boats and avoid crash.
Make sure the steering is correct when rotate the
wheel on the transmitter. Later on when running the
boat you may trim the steering by adjusting the trim
knob on your transmitter until it runs straight when
the steering wheel is at neutral position.
Adjust washer
for prop depth
Congratulations!
Now you are ready to test your boat!
The thrust angle and prop depth are the most
important two factors for cornering characteristics
that you may adjust if you encounter following
situation. Basically the tunnel hull is suit for running
on calm water. All the adjustment must do on calm
water.

MORE RUNNING TIPS!
Besides the “Safety Precautions” at the beginning of
this manual we recommend you read through the
following valuable tips that help you enjoy boating the
Bandit successfully and safely.
Make sure the water cooling system is working
properly or it will cause engine overheated.
Refer to engine manual to lubricate your engine
periodically.
Choose a windless day to run your Bandit as wind
can cause rough water that will affect the performance.
The running of Bandit is about 7~9 minutes (full tank
of fuel). Always notice the running time and have it
back to the shore before engine quits.
Check the lake and wind direction then choose a
good location for boating. The wind can carry it back to
the shore if engine is quit. The following is a good way
to get your boat back. Retrieve the stalled or capsized
model boat with a fishing rod that equips a real. Tie a
tennis ball on at least 12 lb. string.
Do not run your Bandit on a flowing water like creeks
or rivers as well as jump into the water or swim after a
stalled or capsized boat!
Always keep running away from wildlife, do not
intend to threaten with any wildlife with your Bandit.
This is prohibit at any lake or pond.
Happy Boating!
