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,…

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: frequency LoRa modulation protocols update rates hardware antennas transmitter module diversity receivers…

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…

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…

The patch release of INAV, version 2.5.2 was released just today. Below you will find the list of the most critical changes and advice if to update from 2.5.0 and 2.5.1 to 2.5.2. Bug fixes: Fixed a bug that affected INAV OSD menu for editing servo mixer weights. It was not possible to have negative…

There is a group of people who think that the RPM Filter is the best thing to happen to flight controllers and quadcopters since the sliced bread. Perhaps. I’m more inclined to believe that RPM Filter is just an example of good functionality. But it will not be about that, so let’s go back to…

Airplanes are fun, and I like to fly them. Unfortunately, most RC airplanes have a severe flaw: they are big, bulky, and traveling with an FPV airplane can be a pain in a posterior. Sure, some can be disassembled into a few smaller parts, but usually, those parts are not small, and assembling the airplane…

Let’s be honest. INAV is not the most popular flight controller software in the world. Both Ardupilot and Betaflight are more popular, and no one can deny that. Still, the question is: how popular INAV actually is and how many people use it on how many builds? I can not answer most of those questions.…

The most distinctive feature of the EmuFlight flight controller software is it’s gyro Kalman filter. Yes, the same filter that some people name the dynamic PT1, doubt that it works or calls it magic. I will not discuss if the EmuFlight Kalman works and how it works (it works tho, I have enough time in…
