The Readytosky SimonK 30A ESC delivers high-power performance for RC helicopters and quadcopters. The page describes a compact design with 3.5 mm banana connectors and a stable, efficient power supply from an integrated BEC.
The specification list gives a constant current of 30A, a burst of 35A, a 3.5 mm connector size, a 5V/2A BEC output and support for 2-4S Li-ion/Li-poly or 4-12S NiMH/NiCd batteries. It supports throttle refresh up to 621 Hz and uses an ultra-low-resistance MOSFET. The page showed it in stock at Rs 439 (SKU RS8305).
30A constant, 35A burst: as listed.
5V/2A BEC: integrated.
3.5 mm banana connectors: compact and easy to install.
2-4S Li-ion/Li-poly: or 4-12S NiMH/NiCd.
Throttle refresh up to 621 Hz: as listed.
Ultra-low-resistance MOSFET: strong flow capacity.
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.
