Ulanzi VL110 are small but pretty powerful RGB tube lights. Each tube light has 3 modes (white, pulsing, RGB), USB-C charging, an OLED display, and 1/4” tripod mount. On top of that, Ulanzi VL110 can be stacked together to make bigger and longer light. Pretty cool!

The FPV news of the last few days is that Caddx Vista is dead. Or rather, there will be no new manufacturing of Caddx Vista digital VTXes as DJI decided to stop cooperation with Caddx. As Caddx never manufactured Vistas, only cameras, this means that ultimately, Caddx is unable, even if wanted, to produce more…

China is a magical place where you can get everything for a fraction of a price. Like 10000mAh 18650 LiIon batteries for $1.5. Of course, we have to begin with a note, that there are no 10000mAh 18650 batteries! Technology does not allow for such energy density. And if they would exist, they would not…

I designed the Pirx Seven 7-inch FPV frame when the DJI Digital FPV System was something as a novelty. Truth to be told, back then I have not believed it will so popular as it is today. Turned out, I was wrong on that and the DJI Digital FPV System is incredibly popular. Luckily, the…

Why can't I buy DJI goggles anymore All of you who tried to buy FPV goggles in the last three months might have noticed that it was not a trivial endeavor. Starting from the last December, the DJI Goggles and Air Units and Caddx Vistas availability was limited. To some extent, it was due to…

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…
