Where this data comes from
Manufacturer source 2026-09-23: the HDZero VTX User Manual v1.1 lists the Race V2 under 'Discontinued Video Transmitters' (p22) at 34x34 mm body, 20x20 M4 (Soft) mounting, 6 grams, 7V-17V (2S-4S) power input, 5~6W, RF power output 25mW,200mW, Secured U.FL, no antenna included, and its own page (p26) labels the board '20x20 M4 mounting holes' with a 'Rubber Grommet (M4 to M3)' - the same hole-versus-screw pair as the Race V3. weight_g stays at the retailer's 5.9 g rather than moving to the manual's 6 grams: the manual's table rounds every weight in it to a whole gram (7, 6, 28) and 5.9 is the same figure at the resolution the column holds. HDZero's shop no longer lists this model. power_draw is the maker's own supply figure, 'Power Consumption: 5~6W' in the Race V2 (EOL) column of HDZero's discontinued-VTX table, read 2026-10-17; it is the VTX's input draw, not its RF output. channels is the HDZero VTX User Manual v1.1's own list, re-read 2026-10-20: 'Using VTX Menu' (p8) says 'All VTXes support R1-R8, E1, F1, F2 and F4 channels. You will get an additional 8 channels L1-L8 if you unlock the low band', and the 'Unlock Low Band' page (p18) has it flashed from HDZero's Unlock_Lowband.zip after 'Make sure your region allows low band before unlocking' - so 12 is the count as shipped and the L1-L8 band is a regional unlock, not counted. The manual keeps this discontinued transmitter's own page, so the menu line covers it. The manual names channels, not frequencies, so frequency_range stays HDZero's own '5.8GHz' label.
