  • Things that I hate about the DJI Digital FPV

    At first glance, the DJI Digital FPV system is the best thing that happened to the FPV, drones, and airplanes since the LiPo batteries. And yes, DJI FPV is an amazing technology that lets you see so much more and works almost out of the box. It is, however, not perfect and this is my…

  • Li-Ion vs. Li-Po for drones and airplanes?

    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…

  • INAV and DJI HD FPV system – there is a light at the end of the tunnel

    When DJI did not decide to add INAV and Ardupilot to the list of the supported flight controller for the HD FPV system, some people were, at least, disappointed. Long story short: DJI OSD works only with Betaflight. Period. Until today, DJI avoids the answer to the question if INAV and Ardupilot will be supported.…

  • DJI FPV System & INAV – current situation

    When DJI released updated firmware for their DJI FPV system with improved OSD, Betaflight users started cheering. The move to add OSD with elements like GPS position, the artificial horizon, etc is kind of puzzling. It works only with Betaflight flight controllers and a typical user of Betaflight does not really need it. After all,…

  • Matek 1G3 VTX and VRX – Long Range 1.2GHz FPV video link that fits your goggles!

    There a few things that I can be sure of in life. One of them is that every time I receive a DHL package from Matek, there is something very interesting inside! This time, for example, is a pre-production sample of a new FPV transmitter and receiver. This time it’s not 5.8GHz but 1.2GHz. Long…

  • Getting started with Long Range flying – not-so-obvious tips

    This video is for both fixed wing and quad pilots that think about flying slightly further away than usual and have zero experience. I will skip aspects like hardware setup, RC link and concentrate on not so obvious aspects like knowing your ground, trusting your hardware, wind, OSD, directions, planning and so on.

  • Eachine TX805 video transmitter power test

    Let’s measure power output from Eachine TX805 that is supposed to be up to 800mW. Well, it is not. It matches the specification only at 200mW and 800mW is just not there. But, well, it’s only $16 and when used at 200mW or 500mW it works quite well. RF power meter can be purchased for…

  • Realacc UXII circular polarized 5.8GHz FPV antenna – Lumenier AXII chinesium clone

    Cloners gonna clone and chinesium keeps being chinesium! It did not take long for Banggood / Realacc to clone Lumenier AXII FPV antennas and call them Realacc UXII circular polarized FPV antenna. Coincidence? I do not think so. I've ordered few of those in December, they arrived last week and this is what came in…

  • DemonRC NOX5 racing quadcopter is done

    It took my time with this build, that is sure… Somehow there were always more important things to build. Anyhow, DemonRC NOX5 FPV racing quadcopter is finally up and running. What is inside? Nothing special: Frame: DemonRC NOX5 Flight controller: Airbot Omnibus F4 v4 running Betaflight 3.1.7 ESC: DYS XSD30A BLHeli_S Motors: EMAX RS2205S 2300KV…
