BMK Servo e-Timer is a compact timer module designed for free flight models or converting rubber-powered setups to electric. It comes in two variants:
- Servo Version: Changes the servo position when the countdown ends.
- ESC Version: Identified by a red dot. Starts the motor when the button is released and stops it at the end of the countdown.
Both versions support configurable timing between 1 and 250 seconds.
