EU-LBT Version
"Listen Before you Talk" is the abbreviation for a technical feature in radio transmission, which is mandatory for operation within the EU. Therefore, all our remote controls are shipped with this firmware.
This means:
- 4in1 modules are limited to the LBT-enabled protocols FrSKY X/X2 LBT, HoTT LBT, and DSMX
- ELRS modules come pre-installed with EU-approved LBT firmware and are limited to a maximum output power of 100 MW
Battery Included!
On default we ship the radio with battery included. On request we take the battery out and deduct the relevant amount! Please contact us in case you whish to purchase without battery.
