This 30A brushless ESC comes with connectors for RC quadcopters, planes and helicopters. The page says it provides faster and better motor speed control for better flight performance and runs on 2S-3S batteries.
The specification list gives 30A maximum continuous current, a 40A peak for 10 seconds and a BEC of 5V/3A, although the description says the BEC is 5V at 2A maximum. It can be programmed for brake, battery type, low voltage cut-off, start mode and timing. The page showed 165 in stock at Rs 309.
30A continuous current: with a 40A peak for 10 s.
2-3S battery range: listed as 2-3S lixx.
5V BEC: listed as 5V/3A in the specs.
Programmable brake: enabled or disabled.
Selectable start mode: normal, soft or super soft.
Programming-card compatible: works with generic cards.
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.
