Hey Twh,
That setup can definitely work with ExpressLRS. Most ELRS receivers only need three wires: 5V, GND, and TX. Just make sure the flight controller on your Larva X2 has a spare UART RX pad, and enable Serial RX for that UART in the Betaflight Ports tab.
In the Configuration tab, set:
If you get stuck, you’ll find a lot of detailed guides and videos out there. There is a lot of helpful info and great video on plenty of websites.
Joshua Bardwell has a great YouTube channel for visual learners, and Oscar Liang’s site is full of solid technical explanations.

In the Configuration tab, set:
- Receiver mode: Serial-based receiver (e.g., SBUS, CRSF)
- Protocol: CRSF (that’s what ExpressLRS uses)
