Different type of motors will be used on different applications in the RC world. The motors can be classified in brush, brushless and coreless motor.Though inexpensive, traditional "brushed" electric motors offer short run times and limited power. Current passes into the heart of the motor through soft to semi-hard blocks of material called brushes which contact the spinning commutator. Friction from this contact reduces power and causes wear, eventually requiring brush replacement."Brushless"motors avoid these inefficiencies. Current passing around the outside of the motor's can causes magnets on the motor shaft to follow in a circle (imagine the passing current acting like one magnet, pulling the magnets on the motor shaft toward it). Brushless technology is more expensive, but also more efficient-and can be MUCH more powerful!Classify with the rotating type, brushless motor has two type of mechanical design. One is out runner motor, other one is in runner motor. Each of them has their own usage."Coreless motor" is special motor that has been use on the high performance servo. Normally, it is used on the servo.

Nickel Metal Hydride provides incremental improvements in capacity over the Nickel Cadmium at the expense of reduced cycle life and lower load current. Ni-MH batteries do not use heavy metals that may have toxic effects. In addition, they can store up to 50% more power than NiCad batteries and do not suffer from memory effects.
Nickel Cadmium is a well known and understood battery the NiCad is used where long life, high discharge rate and economical price are important. Most Nickel Cadmium battery packs are assembled of 6 or 7 cells for use in cars or airplanes. Each cell provides 1.2V therefore a 6-cell pack is rated at 7.2V and a 7-cell pack at 8.4V. The most popular batteries in use today vary from 1500mAh to 4200mAh. The mAh rating of battery pack determines the length of time your model will run, while adding cells will increase the speed of your model.
Lithium lon fragile technology requiring protector circuit, the Li-ion is used where very high energy density is needed and cost is secondary. Lithium polymer technology provides extremely high capacity in an ultra-low weight package. Unlike any other battery chemistry, Lithium batteries are designed for parallel or series/parallel operation. The more cells you parallel, the more current you can draw from the battery pack.

As the name implies, this device controls the speed of your electric powered vehicle, very much like the throttle control on an engine. Most efficient ESC eliminates the need for a servo as it connects directly to the receiver and provides smooth, liner throttle control and variable brakes. Some units are even available with reverse, or programmable setting function.
