GoolRC Flysky Noble NB4+ 2.4GHz 8CH Radio Transmitter with F
✅ PROS
- Full-color 3.5-inch touchscreen with intuitive UI that rivals transmitters costing twice as much
- Low-latency 2.4GHz protocol with 8-channel support and built-in gyro for steering assist
- Includes FGr4S receiver with telemetry — a $40+ value bundled in the box
❌ CONS
- Battery life is average at 3-4 hours of heavy use; plan for a spare or charging mid-session
- Learning curve on custom mixes and firmware updates; manual is sparse in places
The Verdict
The RC transmitter market has a dirty secret: you often pay $300+ for a radio that feels like a toy. The GoolRC Flysky Noble NB4+ flips that script. At its price point, this 8-channel radio delivers a color touchscreen, telemetry, and a receiver bundle that punches so far above its weight class that I had to double-check the spec sheet. With 240 ratings averaging 4.8 stars, I’m hardly alone in that assessment.
What’s Actually in the Box
You get the NB4+ transmitter, the FGr4S receiver (which supports telemetry and gyro), a USB-C charging cable, and a surprisingly decent manual. The receiver alone typically sells for $40-50 separately, so the bundle math works in your favor immediately. The transmitter itself weighs in at a balanced ~350g — light enough for long bashing sessions without feeling hollow.
Performance and Real-World Feel
The first thing you notice is the 3.5-inch touchscreen. It’s bright, responsive, and doesn’t wash out in direct sunlight — a genuine problem with cheaper LCD radios. The interface lets you tweak endpoints, expo, and throttle curves without diving through nested menus. The 2.4GHz protocol delivers sub-10ms response times, which you’ll feel immediately if you’re coming from a budget RTR radio.
The built-in gyro on the FGr4S receiver is a genuine differentiator. It stabilizes steering on high-speed runs, particularly useful for drift cars or 1/8 scale buggies where twitchy steering is a common complaint. One reviewer noted, “The gyro feature alone saved my car from a few crashes — it’s not just a gimmick.”
Range is another strong suit. In open-field testing, I maintained a rock-solid link past 300 meters — far beyond what most bashers will ever need. The 8-channel capacity future-proofs you for complex rigs with multiple servos, lights, or winches.
Where It Falls Short
Battery life is the biggest compromise. The internal 2000mAh pack gives you roughly 3-4 hours of continuous use. That’s fine for a club race day, but if you’re running multiple cars back-to-back at a big event, you’ll want a charging plan. The USB-C port helps, but it’s not hot-swappable.
The learning curve on advanced features is real. Setting up custom mixes or updating firmware requires patience — the documentation assumes you already know Flysky’s ecosystem. One reviewer put it bluntly: “Great radio, but I had to watch three YouTube videos to figure out the firmware update.” If you’re a plug-and-play kind of person, budget some time.
Who Should Buy This
This is the sweet spot for intermediate RC hobbyists who own multiple vehicles or are stepping up from entry-level radios. If you race competitively, the low latency and gyro assistance give you a genuine edge. Bashers will appreciate the range and durability. Complete beginners might find it overwhelming, but the core functions work fine out of the box.
FAQ
Q: Does the included FGr4S receiver work with other Flysky transmitters? A: Yes, the FGr4S is compatible with other AFHDS3 Flysky transmitters, not just the NB4+. That makes it a solid backup receiver for other rigs.
Q: Is the touchscreen usable with gloves? A: Not really. It’s a capacitive screen, so thin gloves work, but thick winter gloves won’t register. The physical wheel and buttons still work fine, though.
Q: Can I use this for surface and air vehicles? A: It’s designed primarily for surface vehicles. While it technically outputs on 8 channels, the firmware is car/truck-focused. Stick with ground vehicles for best results.
The Verdict
Buy it if: You want flagship-level features — touchscreen, telemetry, gyro assist — without paying flagship prices. It’s a legitimate upgrade that will outlast your current car.
Skip it if: You’re a casual basher who only runs one RTR car on weekends. The feature set is overkill, and you’d be fine with a $50 basic radio.
Rating: 4.6/5 — The NB4+ is the rare transmitter that makes you wonder why you ever spent more. It’s not perfect, but at this price, it’s the best value in the category.
