This ZTW Gecko series ESC

More info:

is a high-quality, efficient brushless electronic speed control. It can operate without the need for a separate receiver battery to power your servos and receivers saving you weight and simplifying your electronic connections (but a separate BEC is required, see below). The Gecko series includes an aluminum heat sink body which is lightweight and helps dissipate heat more efficiently. If you are looking for a top of the line, full-featured ESC at a competitive price, the ZTW Gecko is the logical choice.
