Drone ESC

Choosing a best drone esc combo is a combination of science, guess-work, and
magic! Here is a process to select the "right" motor, ESC and battery.

(1) Estimate the AUW ("All-Up-Weight") of the plane;
(2) Select a motor and propeller with (a) the proper thrust, and/or (b) the
proper power, given the estimated AUW;
(3) Determine the battery voltage compatible with the motor;
(4) Determine what flight times you want;
(5) Select a battery with the desired voltage and capacity;
(7) Determine the resulting current flow in Amps; and
(6) Select an ESC compatible with motor type (brush or brushless motor), and
battery type (NiCD, NiMH and/or Li-poly) that can handle the maximum current
your motor and prop will draw.

After selecting a motor, the next logical step is to select a brushless
electronic speed controller (ESC) that matches your motor. The motor will have
an Amp (A) rating, quadcopter ESC is good general practice to select an ESC
rated for 30 percent or 10A more than the max current draw of your motor. Say I
have a motor that pulls 10 amps. I do not want to buy an ESC that is rated for
10 amps. I would want to get an ESC that is rated for 15 or 18 amps. It is
always good to go higher. The higher amp-rated ESC you get the less heat will
be radiated.
Speaking of heat, this ESC can get very warm at times! That's why it is
important to get an ESC with an amperage rating higher than your motor or your
motor will pull too many amps through the ESC and cause the ESC to overheat and
possible catch fire.

Brushless Speed Controller ESC Types
For base on motor, ESC can be divided into brushed and brushless. It according
to the control signal to adjust the speed of the motor.
#1 Brushed and brushless

For their connection, control ESC usually goes like this:

The ESC input line connected to the battery;
The output of the ESC line (brushed have two lines, brushless have three lines)
connected to the motor;
ESC signal lines connected to the receiver.
