TBS Tracer

Overview

TBS Tracer is a 2.4 GHz radio link focused on low latency control. It is closer to racing and freestyle use than classic long-range Crossfire.

Pros And Cons

Pros	Cons
Low latency	Less common than ExpressLRS
Uses CRSF with Betaflight	Shorter practical range than 900 MHz long-range systems
Smaller antennas than 900 MHz	Smaller ecosystem than ELRS
Good for responsive control	Requires compatible TBS hardware

Betaflight Connection

Tracer uses CRSF, so the flight controller setup is similar to Crossfire:

Receiver TX -> Flight controller RX
Receiver RX -> Flight controller TX
5V -> 5V
GND -> GND
