Flysky FS-NB4 2.4G 4CH Noble Radio Transmitter w/ FGR4 Receiver HVGA 3.5" TFT Color Screen for RC Car Boat (Flysky NB4)

Product Information

The selection of RX that I have detailed above are the cream of what Flysky currently have to offer for mini quad and micro quads, but there are pro’s and con’s to each. The NB4 is the newest, fastest and most stylish ground transmitter to date. Not only does it look great with its new sleek design and metal finish, it also features new flexibility and functionality never seen before in the RC world. Disclaimer: this is NOT a sponsored post, we did not and will not get paid by Flysky for writing this guide. This article was created purely for the benefit of the FPV community, and with the hope that some people who have the passion but with a small budget can find a more affordable way to fly.

I do think that the designers may have pushed appearance ahead of function in some areas, as they have neglected to include trim buttons. Ideally you should trim your craft using the ‘sub-trim’ option in the TX menu, this then saves the trim setting to the model memory data. However I find that it is easier to use the trim buttons to stabilize the craft 1st, then remove trim added via the buttons in conjunction with adjusting the sub-trim through the menu. As you can see, when using a FlySky RX there can be some sacrifices that must be made to ensure you have an operational failsafe. Failsafe is probably not as critical to an indoor model or a micro that you use in the garden, but it is far more important than telemetry. For some reason the most suitable RX FlySky make for larger models (the FS-X6B) only provides a failsafe on the older PWM protocol, which is nonsensical in my view. Another compact and light weight receiver option and with AFHDS2 protocol support. No telemetry, but supports both PPM and iBUS protocols. Compatible with popular radios such as the Turnigy Evolution, FlySky i6S. It also supports failsafe in iBUS.Before we get into the functions, lets have a closer look at the hardware. In case you didn't watch the video I can say if it is silver, it is metal - except for the steering wheel which is plastic. At around 640g all up with the onboard battery plus the clip on lipo base battery it feels sturdy and premium. The most eye catching piece as far the hardware goes is the way the steering works. It's essentially on a rotating arm the goes around 180 degrees to suit either a left or right handed driver. You can stop anywhere in between as well to get the most comfortable position. This is the same as on the regular noble NB4 but this time the mechanism feels more sturdy. While the weight of this RX aims towards micro <100mm models, the length of the supplied IPEX antenna is a bit long to be ideal for this application.

Turn on the transmitter, enter [Sensor] then [Sensor List] and rotate the wheel. If the “Type” column displays “Temperature” and the [Value] column displays a temperature then the installation was successful, otherwise repeat the above steps. Flysky's "Noble NB4" is a 2.4GHz high-end transmitter that is perfect for stepping up from the middle range model and the transmitter for beginners that comes with the Readyset. In addition to the high performance required of high-end R/C systems, the Noble NB4's main feature is a feature that is full of originality. One of them is the adoption of a full-color touch panel display that controls all functions and settings. A wide variety of menus including endpoint adjust, exponential, ABS, and model memory (for 20 cars) can be operated like a smartphone. In addition, since the various setting screens have a graphical design, anyone can change the settings intuitively and easily. Another innovative idea is the wheel mount that rotates 180°, which can be changed to left-handed specifications without changing any parts. In addition, a detachable external battery that can also be used as a mobile battery, dual power supplies with external battery and a built-in battery, two Mini-Z EVO chassis receivers are included, and features and equipment all in one. In addition to the performance advantage, the Noble NB4 is made up of hardware that makes it fun to use the transmitter itself. This guide is to advise which of the less up-to-date products to avoid and point out a few other common areas of confusion. The multi-battery system supports wireless charging, with a super battery lasting capability for more than 10 hours* in the RC marathon-similar distance. Another point in favour of iBUS over SBUS is that the signal is un-inverted, so you are not required to invert the signal when using F1 and F4 boards as you do with SBUS.See here for more details about the differences between the EN version and EU version - he doesn't really mention much about the Asian version, and explains the legalities of using the EN FCC firmware file in the UK The new channel speed segmentation function allows you to set the channel speed in three segments to meet the special needs of high-speed vehicles (drag racing). Aux channels can be used to activate different flight modes, and control different peripherals on a quadcopter such as a lost model buzzer and LED light. With new technology being updated all the time the amount of functions and peripherals we can control from the transmitter are increasing every day. This is a 2-way RX which is capable of providing telemetry from the sensors on the FC to the display on the TX. The FS-X6B receiver provides failsafe capability over both iBUS and PWM. Firstly, there is a wider range of small size RX for FrSky. Although they are generally slightly more expensive, but the full featured options and additional range they provide are worth the extra investment

Noble Pro supports 7 channel modes, that is, 2ch (extreme speed), 4ch, 6ch, 8ch, 10ch, 12ch, and 18ch. The Noble NB4 is equipped with 2 batteries, one in the handle and one removable power bank in the base. The base will charge the battery in the handle when connected and when disconnected the power bank can be used to charge other devices via its USB output. Borrowing heavily from the design of the i10, the FS-i8 isn’t the best looking TX available, (some will say that’s a gross understatement) but that can be put, in-part, down to the large TFT colour touch-screen.The i8 and i10 offer more native channels and are well provisioned with switches, however despite the attempt to integrate the updated technology of a touchscreen, I feel that these 2 fail to provide much actual improvement over the i6X. The FS-i10 is the top of the range offering from FlySky and provides 10 native channels with all the (5) knobs and (7) switches to make full use of them all. Like the i8, the i10 also utilizes a rechargeable LiPo battery and a USB port for charging, connectivity for sims and trainer functions. The FS-A8S was one of the 1st micro RX available for FlySky, it weighs just 1.2 grams, and is commonly supplied with FlySky TX’s as a bundle. The screen feels like it has been pulled from an early model mobile phone - 3.5 inches diagonally with 480 x 320 resolution TFT touch screen. It's bright enough in outdoor conditions (early summer here) and responds well to touch. It does the job it needs to well without being overspecced - for examples a 90Hz full HD+ screen would be wasted in this application.
