  • Jumper T18 radio transmitter and FrSky R9 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 Ghost 2.4GHz long-range radio system

    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…

  • Jumper T18 Review

    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.

  • Long-Range FPV Tips

    Long-Range FPV Tips

    Long-range FPV is one of the hardest aspects of the modern R/C hobby. Not only will you be sending your foam airplane of drone miles and miles above the line of sight range, if anything goes wrong, but you will probably never recover your UAV. Dead servo, burned motor, broken linkage, or just depleted battery…

  • Radiomaster TX16S Review

    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…

  • Dalprop FOLD F5 folding 5-inch propellers

    Foldable propellers are nothing new. We use them on RC airplanes and consumer-ready drones like DJI Mavic for years. But they were never available for 5-inch mini quads! Until now that is, since just today I got a package from Foxeer with 2 (2 and a half) sets of brand new Dalprop FOLD 5.1″ folding…

  • Betaflight 4.2 – new features and most important changes

    It’s been a while since we had the last release of Betalight. After all, Betaflight 4.1 was released in October 2019. Half a year ago. Luckily, developers were not hibernating over the winter, and brand new, 4.2, release is scheduled for May 2020. Slightly more than 2 weeks from now. Below is the list of…

  • What is a PID controller and how it works?

    The whole FPV hobby, and especially multirotor drones, work only thanks to control theory and PID controllers. They are the only thing that separates chaos and immediate flip-over from a stable flight. A regular multirotor has at least 3 PID controllers. If you enable any mode with self-leveling, the number goes to 6. Any GPS…
