Plug and play accessories

Single CAN BUS cable accessories

LX navigation uses CAN BUS interface to deliver power and data to any device connected in the loop which means pilot can setup a new add-on within minutes.

Connect a small, compact AHRS module via single CAN BUS cable to Helios CAN port on the back of the device and AHRS page will appear.
Backup & memory

Backup battery is our standard

All our devices come with backup battery in case of electrical failure with at least 3 hours of battery juice inside.

We have been able to save numerous competition flights with backup battery power and made it a standard, because we understand how important it is, to have a backup.
