King of Shaves catamaran is a beautiful boat. The color scheme
matches the full size off shore racing boat and venom went the
distance including many scale details. The clear wind shield,
realistic looking air intake cowls, and metal exhaust tips put
this boat over the top.
laser cut and sealed boat stand offers a padded surface to display
this beautiful fiberglass boat.
hand laid fiberglass composite hull provides a solid base and
displays the scale King of Shaves graphics with glossy finish
beautifully. The hull is sturdy and a high level of craftsmanship
went into creating this catamaran style hull. Each sponson is
beautifully laid with great detail creating the clean sharp ribs
and steps molded into the bottom.
of foam is secured to the inside of the hull for flotation.
laser cut and sealed wood battery tray, receiver tray, ESC mounts,
and shaft stabilizers are glued to the hull with what appears
to be epoxy or resin. The shaft stabilizers are also reinforced
with an additional layer of fiberglass cloth.
hand laid fiberglass canopy includes a clear windshield and realistic
looking air scoops. Two pins in the front of the hatch work together
with the two Neodymium magnets in the rear to keep the hatch fastened.
Water proof hatch tape should also be added each time you run
to ensure water stays out of the boat. The underside of the hatch
is lines with thin foam just incase.
of the added details include a perimeter glued clear windshield,
molded center scoop, and two fiberglass air-scoops (non functional)
which are held in place with two screws.

Venom KOS brushless catamaran uses dual air cooled Venom V380
2700KV Brushless Outrunner Motors with 3.17mm shafts. The air
cooled motors use a rotating can design. The entire outer can
rotates with the shaft. This is effective in cooling because the
machined blades in the end of the can force air into the motor.
CNC machined aluminum motor mounts use a clam design to secure
the motors in place.
Battery: 2-5 LiPOs
Max Current: 42A
No Load Current: 2.1A
water cooled Venom 60A Pro Marine Brushless Speed Controls are
used to regulate power to the motors. The two ESCs are perched
on two laser cut sealed wood stands.
Venom VR3T 3 channel FM computer radio has many great features.
The multi data display screen clearly displays settings such as
end point adjustments, Steering dual rates, sub trims, channel
reversing, 15 model memories, steering/throttle center, modulation,
brake mixing, function mixing, throttle hold (for gas vehicles),
and fail safe.
buttons are laid out and marked well with an auxiliary switch
on top and steering dual rates on the handle. Throttle hold is
also located on the handle but is only used with gas vehicles.
Venom 4ch PPM/FM receiver operates on the 27MHz frequency. The
receiver is compact and is strapped into the laser cut sealed
wood receiver tray with a hook and loop strap. To keep moisture
out, the receiver is kept inside a balloon which is secured around
the exiting wires with a rubber band.
steering servo used in the KOS is a Venom VEN-1825 high torque
metal gear servo. The servo is held firm by a CNC machined aluminum
mount that has been anodized red. The mount is glued to the fiberglass
hull with epoxy or resin mixture.
first time I tested the Venom 34" brushless King of Shaves
there was a wind advisory with extremely choppy waters. I thought
that would be perfect to see how capable this thing really is.
I started with two 2s 5000Mah 20c LiPO battery packs. I had intentions
of also using the 3s packs but the conditions wouldn't allow it.
electric KOS is wide and sleek in design so it handled the waves
well. I managed to hold full throttle for about 5+ seconds each
pass. The waves weren't my most feared opponent, the wind gusts
were what worried me. Waves are predictable, but strong winds
can be costly. I could feel the wind catch the underside of the
boat at times. I flipped it three or four times total, which isn't
bad at all considering the conditions. Thankfully I sealed the
hatch with waterproof hull tape and the water stayed out of the
hull. The flipped boat floated on its top until I was able to
get the kayak out to right it. Off it went for some more adrenaline
filled power boating.
must say, the rough waters added a whole new level of fun and
excitement to RC boating. The 34" KOS did an excellent job
of bashing through the waves sometimes jumping and sometimes cutting
through. It was cool to watch the catamaran hull dive through
waves to come back up and tackle the next.
boat is definitely a stable one. Even in rough conditions, the
KOS was able to make high speed passes and fairly high speed turns.
KOS performs outstanding on calm waters. High speed passes with
high speed full throttle turns. This boat performs great with
the factory set-up and with a little tweeking, it performs amazing.
I actually tried to flip this boat with 3s 20-25c batteries and
was unable to in calm waters.
E-KOS easily and quickly turns in either direction. Turns are
sharp and stable. During extremely high speed turns, the KOS literally
shaves a layer of water off the top and throws it aside as seen
in one of the action photos above.
full throttle, the boat performs stable sweeping turns. Let off
the throttle some and sharp turns are served.
boat is stable enough for a beginner and powerful enough for the
electric KOS rockets to speed. From a dead stop, the boat actually
launched itself out of the water and quickly reached top speed.
I'm not sure what was more fun, driving at top speed or the thrill
of quick acceleration.
was not an issue with the KOS brushless C1 boat. The counter rotating
props also removed any thought of torque roll. This boat is dead
on when it comes to acceleration.
tested the KOS with 2s LiPOs and 3s LiPOs. The boat is capable
of handling more power but that was all I had at the time of review.
The KOS is no slouch with either battery, but the 3s was definitely
are the top speeds as tested with a GPS unit. Unfortunately, because
of the lack of extra space in the cock pit, I had to put the GPS
in the front of the boat which caused excess nose weight. This
slowed the boat some, so even though these speeds are not a true
depiction of the speeds this boat is capaple of (with the two
batteries below), it's fairly close.
2s 5000mah 20c LiPOs: 28mph with added weight of the GPS. (looks
more like 30-31mph without GPS installed)
Two 3s 3200mah 20c LiPOs: 32mph with added weight of GPS. (looks
more like 34-35mph without GPS installed)
the "c" rating will increase the speed of the boat.
KOS allows for ample time for decent runs. With the Double 2s
5000mah 20c LiPOs I was getting 8-10 minutes of run time.
the Double 3s 3200mah 20c LiPOs I was reaching 8-9 minutes.
See the 34" King of
Shaves C1 brushless off shore racing boat in action!
electric King of Shaves from Venom racing is a well built fiberglass
catamaran power boat with near unlimited potential. Out of the
box this boat is stable enough for a beginner and the dual brushless
motors with dual ESCs provide more than enough power to get your
adrenaline flowing and onlookers eyes popping out. Hopefully not
finish and realistic rendering of the full size King of Shave
C1 catamaran are stunning, to say the least. This is a solid boat
with quality parts. If you like RC boats, you will love the Venom
C1 34" RTR Electric Boat.
