BEC: Battery Eliminator Circuit

UBEC: Ultimate (or universal) Battery Eliminator Circuit

ESC: Electronic Speed Control

BL: Brushless

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.

Rx: Receiver.

Tx: Transmitter.

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
