Velotech Magic Multirotor Speed Controller 40A with SimonK Program OPTO 4 cells When UBEC worksThis ESC performs excellently with most motors. However, due to the limit of SimonK program, we do not recommend this ESC for those big pancake motors with large number of poles, such as SunnySky V40xx, X41xx motors. This is one of the best multirotor ESCs we have tested: quick response, smooth throttle, low running temperature, and high reliability. The ESC comes with no BEC. Featured with high efficiency, all N channel MOSFET design, jitter free
