The Emax BLHeli ESC is a great ESC and comes with the fantastic BLHeli Firmware with OneShot125 Capability
These ESCs also come with a BEC built in. This means you don’t need a separate BEC to power your flight controller.
This ESC comes with bare wires only.
We use these ESCs ourself personally and they are fantastic, they have never let us down and work with High KV motors without de-syncing.
