BEC (Battery Elimination Circuit)
The BEC eliminates the need for a receiver pack to power the radio system. On most electric vehicles
this is located in the electronic speed control (ESC), but can also be a stand-alone device.
BIND Process
Programming a receiver to recognize the GUID code of only one specific transmitter or
transmitter module.
Calibration
Also called ESC setup. It is the process used to match the transmitter throttle, brake and neutral to the
ESC.
Current
Refers to the power flow from the battery to the ESC and Motor when used in the RC vehicle
environment. Typically this is measured in Ampere or Amp.
Deadband
This refers to the amount of travel (movement) on the transmitter trigger before the vehicle is
requesting the ESC to move the vehicle forward or backwards. It is an advanced adjustment used by
experienced drivers.
DSM
(Digital Spectrum Modulation)
The 2.4GHz technology of Spektrum radios.
ESC (Electronic Speed Control)
The ESC is what translates the signals passed from the transmitter trigger through the receiver into
commands that reach the motor to signal forward or reverse, acceleration or braking. The Xcelorin sys-
tem is an advanced electronic speed controller that is very efficient in passing precise requests to the
brushless motor. The BEC is also controlled by the ESC along with the Low Voltage Protection circuit.
GUID
Globally Unique Identification Code. Each individual module or radio is factory programmed with its own
unique serial code. In the binding process, the receiver is programmed to only recognize the GUID code
of one specific radio or module.
LiPo
A Lithium Polymer battery’s abbreviation indicating the chemistry used in these rechargeable
batteries. These batteries require special attention by the user and are only recommended for
the most experienced of users.
mAh
The Milliampere Hour abbreviation, which represents the capacity of a battery pack. The higher this
rating the longer the run time of each charge.
Neutral Position
Referring to the Transmitter when at rest, meaning the throttle trigger and steering have no input. When
you turn the transmitter on, set it to the side while turning the car on, the transmitter will
be in a Neutral state.
NiMH
The abbreviation for nickel-metal hydride rechargeable batteries. These have replaced the use of NiCd
batteries as the battery of choice in RC vehicles.
Profiles
The MSC 12RB has two (2) preset profiles. Forward Only and Forward and Reverse profile. The Forward
only profile can be selected for racing purposes. The Forward/Reverse profile is great for running in
your neighborhood.
Receiver
A device mounted into the vehicle that receives and decodes a signal sent by a transmitter. Servos, ESC
and other devices are plugged into the receiver.
Resistance
As used here refers to the power loss from the battery to the ESC and Motor. Typically this is
measured in Ampere or Amp. Too much resistance between the battery, ESC and motor can result in
low performance and run time.
Servo
An electronic device connected to the receiver used to actuate steering control of the vehicle.
Spektrum
The technology brand of 2.4GHz radio system supplied with the XXX-SCB. The use of this technol-
ogy eliminates the concern of conflicting frequencies found with older legacy radio systems. It further
reduces to a minimum potential radio interference common with the legacy radio systems of the past.
Transmitter
Is the device held in your hand that relays steering and throttle/brake requests made to the receiver.
Trim
This is a setting used on the transmitter to make fine adjustments to the steering or throttle/brake
trigger. For steering you would use the trim to make the adjustment for the vehicle to drive straight
without adding steering input to the transmitter.
Thermal Shutdown
Refers to the ESC operating temperature. The MSC 12RB ESC monitors its internal temperature and
will automatically prevent the ESC from delivering power to the motor, preventing damage due to
overheating the ESC’s electronics.
