Betaflight 4.0 – improved dynamic filtering on 7 inch quad

The next major release of Betaflight will be 4.0 with new and improved Dynamic Filtering. For now, today I only did a quick test of **Betaflight 4.0** running on my TBS Source One 7-inch FPV drone. No tuning, no playing with settings. I only flashed, set modes and radio and that's all. I pretty much like how it feels. This quadcopter was mainly doing cruising, no freestyle, and it felt good to put those props into more demanding use. Yes, Betaflight 4.0 has a good chance to be just awesome…

Hardware

A note about the sound. It indeed sounds like a V8 engine. Bear in mind, that those are default settings and Gemfan FLASH 7042 props are light and do not like to have too much D gain.

Ritewing Mini Drak – The Mist

Ritewing Mini Drak is a very stable airplane, but when the air is bumpy, the flight will be bumpy as well. This is why I'm experimenting with a soft image stabilization.

For video editing, I'm using Magix Movie Studio 15 and it has a built-in video stabilization plugin. But it does not work: waste of time. So, I've got me something else: newBlueFX Stabilizer.

In this video, some of the takes are stabilized, some are not. You should not have much trouble finding which ones I've stabilized with newBlueFx Stabilizer and which not. I've tried to find the settings that are soft enough not to make it look super strange or something. Did I succeed? Not me to judge.

Smooth 7-inch FPV drone – motor soft mounts, part 1

I have a theory that 7-inch FPV quadcopters fly "below expectations" due to frame resonance, I did not expect, so many pilots agree with it. We had nice talks in comments, I've learned a lot about stiffness and moment of inertia (that you Pierre-Louis). Many of you shared some of their tricks and ideas on how to solve that. Let's start testing some ideas how to fix that!

Eachine TX805 5.8GHz video transmitter with SmartAudio review

I love Team BlackSheep Unify Pro series of video transmitters. But they are bloody expensive. $50 for an HV version is way too much in my opinion. Still, I own several of those. Whey on Banggood I've found a presale of Eachine TX805 VTX with SmartAudio for $16, I could not resist and I've ordered a couple of them. This is what came out of it:
