Magic Mini is a series of Velotech miniature ESCs to fit limited space in small multirotors, inheriting the great features and high reliability of the Magic ESCs. Velotech Magic series is one of the best multirotor ESCs we have tested: quick response, smooth throttle, low running temperature, and high reliability. Featured with high efficiency, all N-channel MOSFET design, jitter-free hardware PWM input, and the most popular SimonK program, Velotech Magic speed controllers are an ideal choice for multirotors.Quality electronic parts are used to build Velotech Magic speed controllers, such as genuine Japanese Rubycon capacitor, IOR MOS tubes, heavy duty PCB. These parts cost much more than those cheaper counterparts that are frequently found in low price ESCs.The manufacturing process was strictly controlled and monitored to ensure all electronic parts are properly soldered. Every single ESC was examined in the factory with oscilloscope and other equipments, as well as burn-in test.This product is warranted for six month from the date of purchase to be free from manufacturing and component defects. Limited warranty is handled by Buddy RC at Columbus, Ohio.Specifications:Continuous Current: 16AVoltage Range: 2-4S LiPoBEC Output: N/ARefresh Rate: 600HzMotor Wires: 18 gauge soft silicone wiresBattery Wires: 18 gauge soft silicone wiresDimensions: 23x12x4.5mmWeight:5.6 gramsBootloader: SimonKFirmware: afro
