Its small footprint (25.5 mm by 22 mm by 17.3 mm) and a light 5.1 g mass help keep your model’s balance tidy, whether you are tuning a nimble RC car, a compact speedboat, or a small RC plane platform. The single integrated antenna and straightforward binding experience aim to reduce setup friction so you can focus on your driving or cruising experience.\u003c\/p\u003e\n\n\u003ch2\u003eVersatile data outputs for flexible builds\u003c\/h2\u003e\n\u003cp\u003eThe FGr4S V2 supports multiple data formats, including PPM, i-BUS, S.BUS and PWM. This versatility makes it a good fit for various controllers, servos, and telemetry configurations, allowing you to design a control system that matches your project’s needs without swapping hardware. In practice, you can choose the protocol that best aligns with your flight controller or receiver stack.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eAFHDS 3 technology provides adaptive frequency hopping to help maintain a stable link in environments with potential interference.\u003c\/li\u003e\n\u003cli\u003eThe built-in antenna design simplifies installation and minimizes extra cabling, which can help with space-constrained layouts.\u003c\/li\u003e\n\u003cli\u003eLightweight construction helps preserve handling characteristics for smaller models and reduces the load on your airframe.\u003c\/li\u003e\n\u003cli\u003eTwo-way transmission capabilities may provide transmitter-side feedback about receiver status and input latency, depending on the paired system.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003ePerformance, range, and real-world use\u003c\/h3\u003e\n\u003cp\u003eWhile the product specification lists a ground-range figure greater than 200 meters, real-world results depend on terrain, line of sight, and local regulations. The FGr4S V2 is well-suited to mid-range hobby scenarios, enabling confident control in open spaces and while guarding against unexpected disturbances in cluttered environments.\u003c\/p\u003e\n\n\u003ch3\u003ePower, status indicators, and software updates\u003c\/h3\u003e\n\u003cp\u003eDesigned for flexible power inputs, the receiver accepts 3.5 to 8.4 volts from common RC power rails. A small LED indicator provides a quick status signal during binding and operation. The ability to update the firmware online helps you take advantage of future refinements without replacing hardware.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eCompact two-way package with a built-in antenna keeps the install neat and unobtrusive.\u003c\/li\u003e\n\u003cli\u003eMinimal weight helps you maintain performance and flight characteristics on smaller models.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCompatibility and practical use cases\u003c\/h3\u003e\n\u003cp\u003eCompatibility covers Flysky Noble NB4, NB4+, NB4 PRO, NB4 PRO+, and NB4 Lite transmitters. The four channels support straightforward steering, throttle, and auxiliary control schemes, which makes it a practical upgrade path for hobbyists assembling or upgrading RC cars, boats, or small multi-rotor layouts where a reliable link matters.\u003c\/p\u003e\n\n\u003ch3\u003eWhat’s in the box and binding guide\u003c\/h3\u003e\n\u003cp\u003eThe package includes the Flysky FGr4S V2 Receiver and a binding workflow that is repeatable and easy to follow. The steps emphasize safety and proper power sequencing to ensure a clean bind, with notes on status indicators that help you confirm a successful pairing.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Which transmitters are compatible with the Flysky FGr4S V2 Receiver?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Compatible with Flysky Noble NB4, NB4+, NB4 PRO, NB4 PRO+, and NB4 Lite transmitters.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How do I bind the FGr4S V2 receiver to the transmitter?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Insert the bind cable into the BIND port, apply power to enter bind mode, then bind from your transmitter and verify LED status.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"GIXCEL","offers":[{"title":"Default Title","offer_id":46525756014791,"sku":"B0F59787D6","price":53.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/2355\/7319\/files\/gixcel-fgr4s-v2-receiver-front-view.jpg?v=1778391809","url":"https:\/\/toyterrax.com\/products\/gixcel-flysky-fgr4s-v2-receiver-4-channel-afhds-3-for-nb4-nb4-transmitters","provider":"ToyTerrax","version":"1.0","type":"link"}
