ImmersionRC Ghost is the new long-range 2.4GHz radio system that is getting the most traction in the media in the last few days. However, IRC Ghost is not the first 2.4GHz SX1280/SX1281 LoRa based radio system that has hit the market. FlySky FRM302 TX module and FlySky FTR16S AFHDS3 receiver are available since May 2020, and underneath, they are the same technology as Ghost.

If you ever wondered what is ImmersionRC Ghost and how it differs from the Team BlackSheep Crossfire or FrSky R9* long-range radio systems, this video is for you. In around 15 minutes I get through all the main features of IRC Ghost like:

One of the advantages of the Jumper T18 over its competition is the JP5in1 Multiprotocol Module compatibility not only with 2.4GHz FrSky and FlySky receivers but also with Long-Range FrSky 868/915MHz R9 system. At least in theory, because when I got the radio, I could not bind and use any of my R9MM or R9 Mini with the Jumper T18. However, to make it work, all that is required is to update the firmware of Jumper T18, JP5in1 Multiprotocol Module and, in some cases, in R9 receivers.

ImmersionRC made a surprise and showed a new RC radio link called Ghost. And trust me, this thing, if it will get adopted, will revolutionize the FPV we know today. Why? Because it's a combination of two worlds: 2.4GHz band and LoRa technology known from TBS Crossfire and FrSky R9 systems. All the details of Ghost are not public yet, but based on the manual, specification, and other external sources, I've been able to compile a list of essential things about IRC Ghost.
ImmersionRC Ghost works in 2.4GHz band, but it's into the same technology as existing 2.4GHz radios from FrSky, Spectrum or FlySky. Instead of "traditional" FSK only RF chipsets like Texas Instruments CC2500, it uses Semtech SX1280/SX1281 (I have no solid proof which one exactly but I suspect it's a SX1281) that support both FSK modulation and LoRa. Yes, the same LoRa technology that stands behind TBS Crossfire and FrSky R9.
I will not go in details what LoRa is, but it's super clever Chirp Spread Spectrum modulation that has high sensitivity and can pick up signals that are below Noise Floor. So yes, it can do Long Range for dozens of miles, and you will sooner lose FPV feed than 2.4GHz LoRa signal!

Radiomaster TX16S is one of the most exciting premieres of the first half of 2020. Not only it establishes itself as a second most wanted radio transmitter on the market (right behind radios made by FrSky), it brings a few very interesting features to the table as well. Some of them are:
Today, let’s open a Radiomaster TX16S multiprotocol radio and let’s see how it is built inside. Does the quality match the price?
The year 2020 is exciting in many ways. In the RC and FPV hobby, it’s the year when FrSky is facing healthy competition. FrSky radios like Taranis Q X7 or FrSky X10S Horus can be easily replaced by cheaper, and in some ways better, radios like RadioMaster TX16S or Jumper T18.
Radiomaster TX16S is probably one of the two most awaited for radios in 2020. The second one is the Jumper T18, but let’s not talk about it now. There will be time later to compare Radiomaster TX16S with Jumper T18. Let’s take a look at this hot radio and see what changed, why it looks like black T16, and is it worth the money they ask for it.
The last year was a good year in terms of new radio transmitters. It’s no longer a choice between FlySky and FrSky. We have new players and new products. Below is my, very subjective, overview of the most interesting radios on the market.
In my very personal opinion, FrSky X10S Horus is the best option out there. Some might argue that the shape is not the best, or gimbals are not in the “perfect” place. Perhaps. On the other hand, I do not find those things an issue and I use my X10S for 2 years now. Amazing gimbals, good layout, great LCD and ergonomics. If I would have to find a real-life problem with the Horus, it would be a small battery. You really have to charge it after every trip to the airfield. Besides that, perfect!

FrSky does not sleep, or rather woke up, and after years of not touching the topic, released an “important” update of ACCST 2.4GHz protocol for all the compatible 2.4GHz receivers, transmitter modules, and radios: X9D Taranis, Q X7 Taranis, X10/X10S Horus, X8R, X4R, X4R-SB, XM, R-XSR, XJT and so on.
What changed in ACCST 2.0.0? According to FrSky, they fixed some kind of a bug with uncontrolled servo movement in ceratin conditions (probably almost never) and improved “correction and verification”.
What does it mean in the real world:
Consumer advise? Do not update! There is no need to update from ACCST to ACCST 2.0.0. Looks like there is no gain for end users at all and the cost is substantial!
