Where this data comes from
Read 2026-09-24 off Axisflying's own site, the fourteenth VTX manufacturer catalogue read beside the US retail scrape and the third brand this catalogue carried no transmitter of at all. www.axisflying.com is a UEEShop store with no products.json; its sitemap is named after the domain and is linked only from robots.txt. Its whole transmitter line is /collections/vtx. The brand's own Download Center (/download/vtx) serves six VTX manuals through a public POST (do_action=action.getDownloadCheck), all one-page image-only PDFs rendered here at 6x with Quartz/CoreGraphics. The page's Specifications table states no weight and no dimensions; the brand's datasheet images do, read at full resolution. General Characteristics: Input voltage DC +7V~30V, output DC +5V, IRC TRAMP, Frequency band 3170~3470MHz, 16 channels (Band A 3330-3470, Band B 3170-3310, every step 20MHz), FM/PLL, SMA 50 Ohms, -10C~+60C, Weight Approx 40g, Profile dimension 48mm(L)*32mm(W)*19mm(H) - the same shell as the 1.2G 4W. The RF Output table gives Power Level 0-4 as PIT / 25mW / 200mW / 2W / 4W, matching the page's '25mW/200mW/2W/4W (With PIT Mode)'. input_voltage takes 7-30V because three of this model's own statements say so (the datasheet table, the pin-port table and the interface diagram's '7V-30V' label) against the page block's '7-36V (2-8S LiPo)', which is the 5.8G family's range appearing on a 3.3G page. power_draw is the maker's own supply figure, the 'Current @12V' row of the RF Output table, '160mA±20mA / 580mA±30mA / 660mA±40mA / 1A±50mA / 1.25A±50mA' under power levels PIT / 25mW / 200mW / 2W / 4W, read 2026-10-20 at full resolution (1400 px wide) off the brand's description image on its own product page; it is the VTX's input draw, not its RF output.
