E36+ is a lightweight (<1g) integrated RDT and timer solution featuring DT/Multi-Function servo output and ESC/servo signal output. It’s designed for electric free flight and compatible power systems.
The onboard 434 MHz receiver is fully compatible with all of the BMK RDT Transmitters which can be purchased separately or as part of a bundle.

Detailed instructions on configuration, setup, and firmware options.
The E36+ is designed for use with 5V RC ESC power but accepts any power source from 3–15V. Ensure your servo is rated for the supply voltage.
For rubber-powered or gas models, a 1S battery can be used to power a servo directly via the ESC output pins.

Notices:
1) From 29 Jan 2021, all firmware versions were unified. Mode settings and timer increments (0.2s / 0.5s) are now controlled via button sequences. See the manual for instructions. Older units can be returned for firmware update.
2) As of 18 Sept 2023, the DT Delay (Abad+) function is supported on new units. Use the BMK SkyLink 434 MHz unit to delay the DT timer.
