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
Ohms. 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.
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.
BEC
(Battery Elimination Circuit) – The BEC is used to eliminate
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.
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.
ESC
(Electronic Speed Control) – The ESC is what translates
the signals past from the transmitter trigger through the
receiver into commands that reach the motor to signal
forward or reverse, acceleration or braking.
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.
