INAV 2.5 finally allowed to use INAV and INAV compatible flight controllers to be used on rovers and boats. Finally, INAV supports not only flying vehicles. Bear in mind, that the rover and boat support is not full, and some functionalities might not be working like expected. What works: Reversible ESC and motors Steering Waypoints…

Ritewing Mini Drak is a fantastic R/C airplane. Fast, stable, and thanks to smooth lines and negative swept wing, it looks great. Thanks to negative wing sweep and a long nose, it has a very unusual center of gravity (CG). Mini Drak’s CG is located almost at the leading edge of wings. The Center of…

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 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…

I will be very frank with you: I do not like those tiny whoops. You know, 2″ and smaller propellers, plastic frame, a camera on top. You know, those almost cheapest FPV drones you can get. I’m saying that builds like BetaFPV 65X or Emax Tinyhawk are bad. I just do not like to fly…

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 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…

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…

The last year was a good year in terms of new radio transmitters. It’s no longer a choice between FlySky and FrSky. We have new players and new products. Below is my, very subjective, overview of the most interesting radios on the market. Still the best – FrSky X10S Horus In my very personal opinion,…
