Long-Range RC Links
| System / Peer | RF Type / Band | Output Protocol (RX→FC) | Typical TX Power (selectable) | Representative Line-of-Sight Range* | Notes |
|---|---|---|---|---|---|
| ExpressLRS (ELRS) | LoRA-style / 2.4GHz & 900MHz | CRSF (serial) | 10 mW — 1 W (hw dependent) | 10–40+ km (records much higher under ideal conditions) | Open-source, very low latency, configurable packet rates. |
| TBS Crossfire | Proprietary FHSS / 900MHz (main) | CRSF (serial) | 10 mW — 1 W (regional limits) | 10+ km typical (can exceed 20–30 km with high power & good antennas) | Mature long-range system, excellent link robustness. |
| TBS Tracer | 2.4GHz Tracer (LoRa + Crossfire engine) | CRSF (serial) | 10 mW — 100 mW (device dependent) | ~15+ km (15 mi+) advertised for Nano RX / real results depend on setup | Low latency (250 Hz uplink/downlink), compact receivers. |
| FrSky R9 (R9M/R9) | Narrowband / 868 / 915 MHz | SBUS (or CRSF on some RX) | 10 mW — 1 W (module dependent) | ~5–20+ km depending on power/antenna/conditions | Widely used long-range option on 868/915 MHz bands. |
| ImmersionRC Ghost | LoRa-style modulation / 2.4GHz | Serial (proprietary) | Device dependent (regulatory limits) | 10s of km claimed / >27 km independent tests | High sensitivity LoRa mode, aims at race + long range. |
| DragonLink | Narrowband HF/UHF / 433 / 433-900 MHz variants | Serial / telemetry modem | Typically high power (commercial kits) | 50+ km (commercial claims / long-range aviation use) | Professional/RC hobby long-range system, heavier and more complex. |
