The GlitchBuster Opto-Isolator is designed to work with all popular brands of R/C receivers and servos. It converts any R/C electronic speed control (ESC) with a built-in battery eliminator circuit (BEC) to an opto- isolated input. This isolates any potentially harmful electrical noise from you ESC and motor away from your sensitive R/C receiver; resulting a glitch free operation. The Buster can also be used with a separate BEC that isolates the ESC power source from the receiver's power source. It is also equipped with male and female plugs to provide easy installation.
