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. Page and manual agree on the power steps (25mW/400mW/1W/2.5W with PIT, the manual adding @12V900mA), on MMCX, on the 20*20mm mounting and on 3.3G A/B two groups / 16 frequencies, and the page prints the band edges 3170-3470MHz. They disagree on three other fields, so this page publishes without them: input voltage is '7-36V (2-8S LiPo)' on the page and '9-28V' in the manual; weight is '~25g (excluding antenna)' on the page and '27.5g' in the manual; dimensions are 53x28.85x16mm on the page and 53.79*27.8*13.5mm in the manual - the last being the figure the 5.8G TERKs also carry, so the manual may be reusing the 5.8G shell's sheet. Two manufacturer statements for one field publish neither. power_draw is the maker's own supply figure, the '@12V...mA' tail of the Output Power line in Axisflying's TERK VTX manual (TERKVTX33G25W.pdf), 'Output Power: 25mW,400mW,1W,2.5W @12V900mA', read 2026-10-19 at full resolution off the PDF's embedded page image. The manual does not say at which power level the current is drawn. It is the VTX's input draw, not its RF output.
