BMK E36+ Timer with Integral RDT for Free Flight

Regular price £35.99

E36+ is a light-weight(<1g) RDT/timer solution with DT/Multi-Function Servo and ESC/servo signal outputs.

The onboard receiver is compatible with our BMK B1 transmitter which can be ordered as a bundle or sold separately. Each transmitter has its own unique code and you can connect a transmitter with an unlimited number of receivers.


E36+ is designed to work with RC ESC 5v voltage output but is also compatible with any power supply between 3-15V. Just make sure your servo is supporting the supply voltage.

You can also connect a 1S battery and an additional servo into the ESC power pins if you want to install it on a rubber powered or gas engine model.
