The ReadytoSky 30A ESC is a reliable speed controller for RC helicopters and quadcopters. The page notes that it requires calibration before use, has no forward or reverse capability and works with flight controllers that output PWM.
The specification list gives 30A continuous current, 40A maximum current, no BEC (OPTO) and 2-6S Li-ion or LiPo. The page says the firmware cannot be updated. It has twisted-pair signal wires to reduce crosstalk and supports refresh rates up to 621 Hz. The page showed it in stock at Rs 799 (SKU RS7072).
30A continuous, 40A max: for 2-6S.
OPTO ESC: no BEC.
Refresh rates up to 621 Hz: as listed.
Twisted-pair signal wires: to reduce crosstalk.
MOSFET driver chip: for better performance.
Optimised firmware: with strong compatibility.
An electronic speed controller (ESC) converts the throttle signal from the flight controller into the three-phase power that a brushless motor needs. It switches battery current through MOSFETs at high speed, so the motor turns at the speed that the pilot or autopilot asks for. The continuous current rating shows how much current the ESC can carry all the time, and the burst rating shows what it can survive for a few seconds.
Match the ESC to the rest of the power system. The battery cell count must fall inside the listed range, the continuous current must be higher than what your motor and propeller draw at full throttle, and the signal protocol (for example PWM, Oneshot, Multishot or DShot) must be supported by your flight controller. An ESC marked OPTO has no built-in BEC, so the receiver and flight controller need power from another source. An ESC with a BEC can supply a regulated voltage, usually 5V, to small electronics.
Install and test carefully. Solder joints must be clean and strong, the motor wires should be kept short and tidy, and the ESC needs airflow because current makes heat. Calibrate the throttle range if the ESC needs it, check the motor direction with the propellers removed, and never connect a battery with the propellers fitted while you are working on the wiring. Use a battery with a cell count and connector that suit the ESC, and check for a heat problem after a short test hover.

Simple ESC swaps
This ESC needs throttle calibration before its first use and cannot reverse. It has no BEC, so power the receiver separately.
Firmware updates are not possible, so choose it for simple PWM setups.
Continuous current: 30A
Max current: 40A
BEC: none (OPTO)
Battery: 2-6S Li-ion/LiPo
Refresh rate: up to 621 Hz
Firmware: not updateable
