Attention
These Long Range Systems are capable to use radio frequency transmissions and output power that may
be not allowed in your country.
Please always check your local RF legislation to set the frequency and output power according with
the regulation.
A general rule for RC aircrafts is that they must be controlled always under sight of view, check your RC
regulation to keep up to date with regulations.
Drone Racing Environment
Crossfire Firmware V3.21 and above incorporates Racing Spec Firmware designed for race directors to
effectively manage power output on CROSSFIRE for drone racing.
When using TBS CROSSFIRE control link, it is a requirement that all pilots use exactly the same power
output. Use of CROSSFIRE has the same requirement as management of video transmission power output
when it comes to racing.
Recommended power output is generally 100mW, however in some countries the maximum will be 25mW.
Please check your countries regulations. The New LED Color System on the TBS CROSSFIRE allows Race
Directors to see the power output at a glance.
Note:
Use of different power outputs during racing can cause control lockouts for pilots.
Crossfire LED Color Coding
LED on the back of TBS Crossfire Module will Illuminate in either blue or purple which will indicate the
power output being used. If LED on the back of module is any colour other than blue or purple, this
indicates pilot is not using Racing Spec Firmware or they are using higher power output than other
competitors.
Turquoise LED = 25mW
Blue LED = 100mW
Green = Above 100wW
Color enables Race Directors to easily identify if there are any power output inconsistencies.
Note: Dynamic power must be turned OFF and telemetry should be ON or OFF depending on Race Director
decision.
