START UP
1. Turn on the transmitter, taking note that the power light is
illuminated on the transmitter.
2. Stand clear of the propeller and plug each of the main
power batteries into the ESC.
3. At this time you will hear one beep. To arm the ESC
squeeze the throttle trigger and hold until you hear one more
beep. Release the throttle trigger and you will hear three
more. You boat is now ready to operate.
Review:

➙ Three (3) beeps
Ready to operate
4. Now is a good time to check the rotation of the prop. Very
quickly jab the throttle trigger and check the rotation direction of
the motor. It should spin the propeller counterclockwise. If the
motor spins the wrong way, simply switch any two of the three
wires between the motor and ESC. WARNING: DO NOT hold
the throttle down for more than one or two seconds to check
the motor direction or you might risk damaging the motor.
5. Tape the cowl in place carefully, making sure you press it
securely down. Make sure you use a good quality hatch tape
like GrimRacer Pro Radio Box Tape. Other radio box tapes
can leave sticky adhesive that can be hard to remove.
6. Snap the forward canopy in place. Your UL-1 is ready to
dominate the water.
LAUNCHING THE UL-1
You can set the boat still in the water and hit the throttle or
hand launch it. The boat is designed to leave using either
method. When using the still method, you are going to have to
be quite aggressive with the throttle to get the boat on plane
but once on step you can back off. Having said this, if you
operate your boat at “less than full power” for the full duration
of the run, you might likely experience an ESC failure. The
extra voltage the batteries deliver is being managed by the
ESC and can cause the ESC to get hot enough to fail. When
doing a hand launch toss the boat in the water with a forward
motion. As the boat hits the water, apply throttle.
Its also good to note that ANY weeds, duck feathers or other
obstructions that could get hung up on the running hardware
can and will affect the performance of your UL-1. Any extra
drag can cause your power system to overheat and do a
thermal shut down or possibly fail. It is best to operate your
UL-1 in water that is weed free and clear of all obstructions.
If your ESC “thermals” in a short time, it will cool and you will
be able to re-arm the ESC.
MAINTENANCE
SIMPLE MAINTENANCE TIPS:
• After each run remove the drain plug from the transom and
drain any water that might have entered the hull.
• Allow the electrics to cool after each run.
• Check your prop for nicks or damage after each run.
• Lightly re-grease the drive cable every 6 or 7 runs.
• After running for the day remove the drive cable and wipe
away any water. Lightly re-grease the drive cable and re-
install in the boat.
• Spray WD-40 or some other water displacer through the
cooling system to prevent any oxidization of the metal parts.
• Clean the exterior of the boat and leave the canopy and
cowl off overnight to allow any water to evaporate that
might be in the center tub.
• At your earliest convenience re-charge your LiPo batteries
and store them in a safe storage container.
