About this deal

The box is REALLY nice. Well made too and aluminium with a carbon fibre effect printed over it. Very sturdy but lightweight and does not wobble around or anything. 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.

DUAL BATTERY SYSTEM: The 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 using its USB output. The Turnigy Evo is not a Flysky TX, but we’d like to include it in this list because it uses the same TX protocol as Flysky TX’s, and it’s compatible with Flysky’s RX as well. I cannot fault the Noble. It's simple stupid. Nice and easy to get around, simple to change settings and there is always help if you need it. The TX will beep and vibrate when you make a selection or change - this may or may not drive you nuts but you can turn it off at anytime. Thanks to Loopyroberts for his comment below confirming that the i10 does support the original AFHDS system, so you will be able to bind with older FlySky RX.Similar to SBUS, iBUS is a digital serial protocol that allows for up to 18 channels to be supported on a single wire (compared to the 16 channels offered by SBUS). These digital protocols have less latency than PPM, providing an overall better solution to traditional analogue RX signals. Channels 1 to 4 are used to control the actual movement of the craft, while the rest of the channels are assigned to the switches and pots (potentiometers) on the radio, and are referred to “Auxiliary Channels”, labelled as AUX 1, AUX 2 and so on. You can use the Turnigy Evo to play simulators, and it supports PPM, SBUS and iBUS receivers which is great for mini quad. Flysky RX Options

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. The 2CH (extreme speed) mode breaks through our limit of latency and opens up a new range by using the new radio frequency library algorithm. The multi-dimensional adjustable and expandable system and new ergonomic design The Eachine Minicube Flysky RX is a great option for outdoor models between 100mm and 180mm due to its 20x20mm mounting pattern, and pre-installed buzzer. 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.

NB4 Pro - amazing + some bonus bits if a little pricier. Twice the price for a few extra functions, some TX jewellery, carry case and extra setup bits? I’m on the fence still. Noble Pro supports temperature, voltage and speed sensors (both magnetic and light induction). The transmitter can display information such as receiver supply voltage, RSSI and signal strength in real-time.
