Who could have imagined that tricopters can be so much fun? For sure they are interesting devices that lost a lot of "market" when quadcopters gained extra torque and plenty of reaction moment to do fast yaw turns. Almost no one flies them now. Too bad… And good luck if you want to buy a tricopter frame for 5-6 inch propellers. There is almost nothing on the market right now!
Luckily, we are living in interesting times, and everyone with few hundred dollars can get a 3D printer and make whatever he wants (right, if it was that simple…). Thanks to this, I give you a 3D printed tricopter frame designed to use miniquad parts: 2205 motors, 5 inch propellers and 9 gram servo:
FrSky R9 radio system is storming the RC hobby. It's super cheap after all. But there are problems: EU version is facing a lot of problems and people like to replace original antennas with something else.
Last week I was asked to check what is going on with antennas shipped with FrSky R9 Mini. After all, the same hardware can be used both for FCC 915MHz and EU 868MHz version. Is the antenna tuned somewhere in between? Or not so much?
220x motors are the workhorse on the RC hobby right now when it comes down to mini quads. Sometimes they are joined by 230x too. But 2205 and 2206 brushless outrunners have a serious problem that limits their use with propellers bigger than 5 inches. They might still be fine with 6-inch props, but on 7-inches problems begins. What 220x lack is torque! They are just too small to have enough copper wire and diameter to deliver enough torque to drive much heavier 7-inch propellers.
Is Matek F722-SE the best flight controller of 2018? Perhaps it's "slightly" too early for such statements, but for sure, it looks like one of the strongest pretenders for such a title (if the title existed).
In a meantime, a video showing brand new Matek F722-SE flight controller and most of its features.
I have to honestly admit, up to the beginning of 2018 summer I was rather against 4-in-1 ESCs and flight controllers combos. The reason was quite simple: 4-in-1 were a rather new thing, had a tendency to burn without a reason and were quite expensive. Pretty much a normal state of a new technology. In comparison, FC + PDB + 4 separate ESC had more flexibility, were cheaper to replace when something puffed the magic smoke and seemed to be a reasonable choice when few extra grams of weight was not a problem. Lately, things started to change…
4-in-1 ESCs are no longer a new thing, manufacturers learned their lessons and prices went down! And that means you can get a decent quality flight controller and 4-in-1 ESC for less than $50. That's cheaper than 4 ESCs! C'mon, things ARE happening.
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…
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.
Hey, don't leave yet, there is more!
Do you know that there is a YouTube channel with awesome, drone and FPV related video? Why don't you give it a try?
