This SunnySky X series 18A airplane ESC features 2-6S LiPo input, strong 4A BEC, one key to change propeller rotation, programmable BLHeli_S firmware, a fast 32bit processor, and lightweight, smooth operation.
We highly recommend using this ESC with SunnySky small X series motors, such as X2204, X2206, X2302, X2305, X2306, and those R series competition F3P airplane motors including R2304 and R2305. All these motors have 2mm bullet connectors soldered in the factory and can be plugged into the bullet connectors of the ESC directly.
