After the introduction of RB30/RB50 high performance
brushless speed controllers, TEAM WAVE has targeted
development on a stock class optimized brushless speed
controller. In 2010, TEAM WAVE is proud to present the
stock spec brushless speed controller RB-S.
Stock spec racing is the most popular and competitive
class all over the world. Even non experienced drivers
can enjoy RC racing in stock class. With brushless motor
technology, drivers can now concentrate in improving
their driving skills instead of tuning and maintaining
In the past, high performance brushed motor is the
key to win in stock spec racing. Factory team drivers
with the best resources and access to selected motors
usually dominate in this class. Nowadays, performances
of brushless motors are very close between different
brands and instead, the speed controller plays a more
important role. In stock class racing, a well designed
stock spec brushless controller can out-perform more
expensive general purpose / modified class oriented
speed controller. This is the mission of RB-S, a purpose-built
stock spec brushless speed controller.
Twin Turbo Technology
Based on the highly successful turbo technology used
in RB30/RB50, TEAM WAVE now introduces TWIN TURBO technology
in RB-S. Twin turbo technology offers double the power
that single turbo offers. It drains large amount of
electric current to the motor and push the motor to
its limit instantly. Drivers can feel turbo kick in
just like the engagement of the second gear in nitro
RC car. With such feature, drivers no longer need to
lower the gear ratio in order to gain top-end speed
but sacrificed low-end torque and punch.
Turbo technology is also very useful in off-road application,
especially in stock spec racing while the car does not
have enough power in some long jump or double jump.
Turbo can deliver power to the wheel instantly for the
jump and maintain smooth control in the rest of the
Extended Time Shift technolohy
Compared to other sensored brushless system, TEAM WAVE
raised the bar to the next level by introducing the
"Time Shift" technology - motor timing is
no longer fixed in sensored brushless system. Together
with Turbo/Twin turbo technology which gives an instant
power boost to the motor at full throttle, smoothness
and high top-end speed can now be achieved at the same
Based on the "Time Shift" technology used
in RB30/RB50, RB-S features extended "Time Shift"
technology in which 2 more steps are available (5+2=7).
The diagram above shows how Turbo and "Time Shift"
work together. Twin turbo can give much higher speed
and acceleration when engaged. Higher "Time Shift"
offers smoother transition during turbo engagement and
it is especially useful in stock class racing.With Turbo,
Twin Turbo, extended "Time Shift" and mechanical
motor timing, racers can find the best to suit for any
driving style, track layout, track size and condition.*
Smooth throttle response
Smooth throttle and brake responses are the keys to
fast and consistent lap times. RB series brushless controller
features 10-bit resolution in both forward and brake
mode, i.e. 1024 steps for forward and 1024 steps for
brake! Together with 9 throttle and 9 brake curves,
there is always a profile that suits your driving style.
RB-S features bit-to-bit mapping technology
such that every bit on the radio signal is directly
mapped to the throttle signal. Since the radio signal
always has much lower frequency than the throttle signal,
manufacturers usually use different resolution for these
two signals, resulting in data loss or under-resolution.
With bit-to-bit mapping and fast signal processing algorithm,
the motor can respond to the throttle trigger more naturally,
accurately and responsively.
in small size
The size of the controller is not compromised for high
performance in the RB series. By utilizing high density
multilayer multistack PCB, RB series brushless controllers
provide enormous power to today's high-drain motor and
at the same time features an ULDO (Ultra Low Drop Out)
BEC (Battery Eliminated Circuit) which can deliver 3A
continuous current without significant voltage drop
(BEC output 6V at normal and over 5.6V at 3A load).
Your expensive steering servo can now work at full force
and won't loss power/speed at high traction tracks or
A specially designed ventilation hole is drilled through
the heatsink such that cool air can be blown directly
into the controller to cool down the lower stack MOSFET
and the hot air can then escape from the back of the
High quality and high
Every component used in the RB series is carefully
chosen and specially designed with high quality and
fidelity at a reasonable price. All components are imported
from the original manufacturer and all controllers are
designed/made in Hong Kong which ensures highest quality.
Our passion is embedded in every design detail and no
other OEM products can compare.
RB-S is capable of updating firmware through the optional
handheld programmer. The handheld programmer not only
provides easy setup of the controller but also features
a USB link. With updateable firmware, you can enjoy
all new features later without paying extra!

*Zero (middle B) is recommended for the mechanical motor
timing if turbo/twin turbo is applied.
*Mechanical motor timing should be inversely proportional
to "Time Shift" setting (when TURBO OFF) such
as low mechanical motor timing for higher "Time
Shift" and higher mechanical motor timing for lower
*Adjusting mechanical motor timing needs advanced skill
and experience. It is not suitable for inexperienced
users. Improper tuning of gear ratio, mechanical motor
timing and ESC settings will result in damages of both
ESC and motor.
*Motor temperature should be monitored at all time.
