For years, long-range drones were associated with big and purpose build (mainly lightweight) quadcopters. With at least 7-inch propellers, but true long-range started at 8-inches or more. Times changed, and in the 2020, a new class of long-range FPV quadcopters emerged: light, dead-cat frame, 4-inch propellers, weight around 250g, and with flight times somewhere between…

Lithium-Polymer (LiPo) batteries dominate the RC hobby. In like 98% of the cases, if you have a drone or RC airplane, or RC car, it is powered by a LiPo battery. The reasons are simple: they are high current capable, fast to charge, and have relatively high energy density. LiPo is, however, not the only…

The question "What is the best flight controller firmware?" pops up here and there from time to time. Some say it's Betaflight. Some say it's Ardupilot. And reality? Reality is often disappointing, and there might be no one answer to that question. Every flight controller firmware has strong and weak sides. Ardupilot sucks on small…

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…

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: Built-in multiprotocol module…

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.
