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 Gyro, Looptime and Gyro Stage 2 Lowpass Filter
Betaflight 4.2 brings some very important changes to how various tasks are processed. Especially how gyro,m filtering and PID loop are working together. First of all, the gyro is sampled always at the gyro native speed. This means, MPU6000 will be sampled at 8kHz. Always. At the same time, PID and filtering are working as…

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…

ESP8266, ESP32 and ESP32-S2 comparison
Currently, there are 2 types of MCU from Espressif on the market: ESP8266 from 2014, ESP32 from 2016 and ESP32-S2 that debuted in the second half of 2019. Although ESP32-S2 is not yet very popular, it is expected it will replace ESP8266 as a cheaper, more powerful and more secure alternative in the upcoming years.…

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…

Betaflight vs EmuFlight vs INAV
Which flight controller software flies better out of the box? You know, the stock, default settings, no tuning. Just flash and fly. Betaflight, INAV or maybe EmuFlight? I decided to test it on one of my 5-inch FPV drones and compare: Betaflight vs INAV, Betaflight vs EmuFlight and EmuFlight vs INAV. The results are divided…

What is EmuFlight?
Here is a short story of what is EmuFlight, how it differs from Betaflight and should you even care? To answer the question. Yes, you might want to take a look at it. It is different enough from Betaflight to consider it as a separate flight controller. And some people say it really fly great…
