What is ExpressLRS (ELRS)?
ExpressLRS is a high-performance, open-source RC system for FPV drones. It’s known for record-breaking packet rates (up to 1000Hz), exceptional range, and low cost.
Key Features
- Ultra-Low Latency: Down to 4ms in F1000 mode.
- Frequency Flexibility:
- 2.4GHz – smaller antennas, best for racing/freestyle.
- 900MHz – better penetration & range.
- LoRa Modulation Across All Rates: Maximises range even at higher packet rates.
- Gemini Mode (v3.3+): Sends and receives simultaneously on two antennas/frequencies for link stability.
- Dynamic Power: Adjusts TX power automatically based on signal quality.
- True Diversity Support: Uses two independent RF chips for maximum reception reliability.
- Extensive Telemetry: LQ, RSSI, VBAT, GPS, and more.
Pros
- Most affordable long-range system.
- Highest update rates in the hobby.
- Open-source = wide hardware compatibility.
- Constant innovation from the community.
Cons
- No data encryption.
- More complex setup for beginners.
- Limited to 12 channels.
- No SNR reporting (yet).
What is TBS Crossfire?
TBS Crossfire is a proven, proprietary long-range RC system trusted by professionals for years. Known for bulletproof reliability and deep signal penetration, it’s the gold standard for mountain flying, dense forests, and extreme long-range.
Key Features
- Frequency: 868/915MHz for superior obstacle penetration.
- LoRa Modulation (50Hz): Exceptional long-range performance.
- Dynamic Packet Rates: Adjusts automatically to maintain link stability.
- Encrypted Link: Protects against interference and hijacking.
- Integrated Ecosystem: Works seamlessly with TBS VTX, antennas, and peripherals.
- Telemetry: LQ, RSSI, voltage, GPS, SNR for better noise environment monitoring.
Pros
- Rock-solid reliability in all environments.
- Superior penetration through obstacles.
- Encrypted communication.
- Mature, stable firmware.
- Strong integration with TBS products.
Cons
- More expensive.
- Lower maximum update rate (150Hz).
- LoRa only at 50Hz — range drops at higher rates.
- Proprietary — limited to TBS hardware.
Signal Health – LQ & RSSI
Both systems report:
- LQ (Link Quality): % of clean data packets received.
- RSSI (Signal Strength in dBm): Measures raw signal power.
💡 Pro Tip:
Monitor both LQ and RSSI in your OSD.
- LQ drops first when interference increases.
- RSSI drops gradually as you approach range limits.
When to Choose ExpressLRS
- You want the best performance per dollar.
- You enjoy customisation and frequent firmware updates.
- You fly mixed brands and value cross-compatibility.
- You want racing-grade latency with long-range ability.
When to Choose Crossfire
- You prioritise maximum reliability over experimental features.
- You often fly in dense, obstructed terrain.
- You want encryption for secure links.
- You prefer a polished, plug-and-play experience.
Bottom Line
- Choose ELRS if you want cutting-edge performance, low latency, and flexibility at the best price.
- Choose Crossfire if you want a rock-solid, encrypted link and the confidence of a mature ecosystem.
