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 V3.23 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 sa…

The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] · [√f(GHz)] ≤3.0 for 1-g SAR and ≤7.5 for 10-g extremity SAR,24 where • f(GHz) is the RF channel transmit frequency in GHz • Power and distance are rounded to the nearest mW and mm before calculation25 • The result is rounded to one decimal place for comparison • 3.0 and 7.5 are referred to as the numeric thresholds in the step 2 below Result: (13.462/5)*√0.90275 = 2.558 <3.0 (13.556/5)*√0.91475 = 2.593 <3.0 (13.493/5)*√0.92725 = 2.599 <3.0 Conclusion: No SAR is required.
