The Cyclone 45A ESC uses a premium 6-layer, 3-ounce copper-thick PCB to improve anti-jamming performance. The page describes a built-in RGB multi-colour LED, DShot digital throttle compatibility and BLHeli-S firmware.
The page is inconsistent on its ratings: the title says 45A but the specification table gives a working current of 35A, and the description names DShot 150/300/600 while the table names dshot 125/300/600. Use the lower 35A figure when you size your power system. It supports a 2-6S supply, with an 18AWG 90 mm power cord and a 150 mm signal line. The page showed it in stock at Rs 956 (SKU RS7318).
6-layer, 3-ounce copper PCB: to improve anti-jamming.
Gold-plated PCB: as listed.
Built-in RGB multi-colour LED: as described.
DShot digital throttle: with BLHeli-S firmware.
Regenerative braking function: as listed.
2-6S power supply: as listed.
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.
