BEC: Battery Eliminator Circuit
UBEC: Ultimate (or universal) Battery Eliminator Circuit
ESC: Electronic Speed Control
COG or CG: Center of Gravity. "Cog" could also mean motor cogging, but the letters are not usually all capitalized.
CD: Center Differential
MM: Mamba Max or MetalMan :)
MMM: Mamba Monster Max. Will be here someday.
RPM: Revolutions per Minute or the RPM company
KV: RPM per volt motor constant
Y or Wye or Asterisk or Star: A brushless motor coil configuration. Looks like the letter Y.
D or Delta or Triangle: A brushless motor coil configuration. Looks like a triangle.
CC/CV: Refers to the Constant Current/Constant Voltage threshold for lipo charging.
CC: Castle Creations company.
LMT: Lehner Motoren Technik brand of brushless motor, commonly shortened to simply Lehner.
S, L, XL: Refers to the motor can length when talking about Feigao/Wanderer/Nemesis brushless motors.
S&T: Sky and Technology company - makes the Quark ESCs.
MGM: ESC brand.
AC: Alternating Current
DC: Direct Current
PWM: Pulse Width Modulation. Refers to the method ESCs use to send partial power to a motor. Highly efficient. Can also refer to the signal from a radio receiver to servos/speed controllers.
RCM: RC Monster. Can refer to the main site, the forum site, or "the man" Mike.
LVC: Low Voltage Cut-off device to protect the lipo cells from being discharged bellow 3V per cell
HV: High Voltage
FET: Field-Effect Transistor. High current devices used in speed controllers that channel battery current to the motor.
MOSFET: Metal-Oxide Semiconductor Field-Effect Transistor. Other less common versions: Metal-Oxide Silicon Field-Effect Transistor, and Metal-Oxide Substrate Field-Effect Transistor.
NiMH: Nickel Metal Hydride Battery
NiCD: Nickel Cadmium Battery
Lipo: Lithium Polymer Battery
Cap: Actually not an acronym, but an abbreviation for capacitor.
A: Amps. Electrical term for current.
V: Volts. Electrical term for voltage.
W: Watts. Electrical term for wattage or power. 1 horsepower = 745.7 watts.
mAh: milliamp-hours. Battery capacity rating. How many milliamps a battery can deliver for one hour. There are 1,000 milliamps (mA) in one amp. So 1000mAh is the same as 1Ah.
WOT: Wide Open Throttle
Forum "shorthand" acronyms:
IIRC: If I Remember Correctly
ATM: At The Moment
IMO: In My Opinion
IMHO: In My Honest (or Humble) Opinion
BTW: By The Way
OTOH: On The Other Hand
AFAIK: As Far As I Know
FWIW: For What It's Worth
FYI: For Your Information
ATB: All The Best
FTW: For the Win
