I gave it 4 star tho because being powered from 7+ you can't use a 5v pad to power the vtx. Has to be directly from lipo so you have to add a low esr capacitor to get rid of ton of video noise. After you add the cap it's a great vtx ## Frequently Bought Together - AKK FX3-ultimate 5.8GHz 25mW/200mW/400mW/600mW Switchable Mini VTX Support OSD Configuring via Betaflight - SoloGood Caddx Ant FPV Camera 1200TVL Global WDR OSD 1.8mm Nano FPV Camera 16:9 NTSC PAL for RC FPV Cinewhoop Tinywhoop Drone - SpeedyBee F405 Mini Flight Controller Stack board 3-6S 20x20mm Built-in Bluetooth with 35A BLHeli_S 4in1 ESC Board Support Wireless Tuning --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/72633632-fx3-ultimate-5-8ghz-25mw-200mw-400mw-600mw-switchable-mini](https://www.desertcart.tn/products/72633632-fx3-ultimate-5-8ghz-25mw-200mw-400mw-600mw-switchable-mini) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-11*
