VTX Energy Testing

Utilizing the ImmersionRC Energy Meter V2, I examined the VTX RF energy output of the BetaFPV Air 5in1 FC. Listed below are the outcomes:

R1 R2 R3 R4 R5 R6 R7 R8
25mW 32 36 43 46 54 59 55 42
100mW 82 / / / / / / 162
200mW 161 / / / / / / 326
400mW 262 / / / / / / 550

For comparability, listed below are the measurements for the earlier Air 4in1 FC:

R1 R2 R3 R4 R5 R6 R7 R8
25mW 40 38 34 26 26 30 23 20
100mW 50 80
200mW 85 141
400mW 144 315
