The HobbyKing 3A Single Cell Brushed Motor Speed Controller is designed for single lithium battery driven micro RC model applications. It is extremely light and is the perfect choice for indoor ultra micro airplane and helicopters. Due to the continuous 3A current capability, it is the perfect choice of wide range brushed motors. The ESC also features built in battery low voltage cut-off and high throttle start up protection, to ensure the safe operation. There is no integrated BEC circuit as this ESC works with a single cell Lipoly, RX power is therefore supplied at 1s voltage.
