The SimpliFly 40A ESC is a high-performance speed controller for brushless DC motors that supports 2S to 6S LiPo batteries. The page describes ultra-smooth control through DShot and OneShot125 compatibility and programmable motor direction for drones, RC planes and helicopters.
The specification table gives a 7.4V to 22.2V voltage, 40A continuous, 50A burst, dimensions of 65 x 22 x 5 mm, a weight of 25 g and a black colour. Optimised software supports disc-type motors and all settings except timing are predefined. The page showed only 1 left at Rs 921 (SKU TIFQC0198).
40A continuous, 50A burst: for 2S to 6S.
DShot and OneShot125: listed as DShot1200 on the page.
Twisted-pair throttle signal cable: as listed.
Signal frequency up to 12 kHz: compatible flight controllers.
Programmable motor direction: as listed.
Overheat, overcurrent and low-voltage protection: 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.

The ESC works with flight controllers up to a 12 kHz signal frequency. The package includes 3 bullet connectors and a user manual.
The page prints the protocol as DShot1200, which is unusual, so check what your flight controller supports.
