A very cool, futuristic looking, 3D printed quadcopter frame

I love this part of me being a creator and an influencer, where I can show you some amazing things created by other people. And today, the joy is double, because it is an extremely cool frame designed by a guy from Spain that goes under the nickname of Micrathene FPV.

3-inch 3d printed FPV drone frame

What it is? Well, like I mentioned, it is a fully 3D printed 3″ FPV frame with a place for a GPS, FPV camera and (yes, I’m not joking on that) camera tilt! There is enough space inside for a servo and a camera mount is pivoting by default.

Pirx Seven – The ultimate custom 7-inch FPV frame, part 1

Do you know this old saying “If you want something done right, do it yourself”? I do and sometimes I just live according to it. Not always, I’m not crazy, but at least from time to time!

I fly 7-inch FPV drones a lot. To be honest, they are my favorite flying devices. There are a few good 7-inch frames, like TBS Source One for example. There is a difference between good and great tho. I do think that Source One is a good frame, there are a lot of things on it that do not make me very happy tho! The list might not be very long, but it is relevant:

  • props in the view
  • limited space to install split-like hybrid cameras
  • no very convinient place to install VTX
  • it’s not that big inside as one might imagine…

Your first 7-inch FPV drone

I love 7-inch FPV drones and during the last year, they were my most used FPV gear. For freestyle, cinematic, cruising and long-range. I currently own 3 7-inch FPV drones and 4th one in the assembly process.
I think of myself as a 7-inch expert. I’ve wasted enough money and equipment to know what works and what does not work well with 7-inch propellers.

If you are thinking about building your own 7-inch FPV drone, here are some tips that might save you a lot of time and a lot of money on wrongly chosen equipment. Read More

Armattan Marmotte Schmarmotte

This is my second adventure with Armattan frames. The first one was Rooster. And it would be great if not moving arms. I yielded again and got me an Armattan Marmotte this time. I recorded this video before flying it. When I write those words I already know how it flies. It flies good, but I still have to tune and update motors to something more modern and not beaten up. In other words: Armattan Marmotte is great in the air but some of the design elements are extremely bad!

7″ FPV frames – window shopping on Aliexpress

7-inch FPV quadcopter drones are getting more popular and because of this, Chinese manufacturers are finally putting new frames on the market. While even 6 months ago the choice of 7-inch frames was very limited, now you have at least a half-dozen choices when you want to buy cheap from China. Let’s go to Aliexpress and do some window shopping (not licking 😉 )…

Frames from this video:

First glance at Armattan Rooster FPV quadcopter drone frame

After flying chinesium (XMR250, Reptile X4R 220, Martian II) and frames from DemonRC I’ve decided to switch to completely different brand. My choice is Armattan Rooster, the newest freestyle frame from Armattan.

Rooster arrived few days ago, and this is what I can say about it before putting all the stuff into it:

  • sunken nuts you have to install by yourself are a very idea. It’s hard to do without tools and skills. It would be much much better is they were preinstalled. Armattan, please, fix it!
  • additional pair of standoffs between plates would not hurt
  • it is tight inside and I will have to be creative to fit X4R and TBS Unify Pro in the back of the frame
  • frame itself looks good tho. I might even say it is pretty

3D printed racing drone, part 3

It is done. It is alive. My 3D printed FPV racing drone works. A few weeks ago I finally flight tested my design and it works! Even better than expected, since I survived the experience without a scratch. OK, I did not crash it yet, but give me some time for that too….

And I have a cool name for it: Isando which means hammer in Zulu. Kind of fits, right?

Ah, STL files are available on Thingiverse of course.

3D printed racing drone, part 2

My 3D printed racing drone is done. More or less. I was able to finish it a few weeks ago and even perform a maiden flight. It survived the experience, but I also discovered few problems I will have to solve before officially calling this project a success.

First of all, the decision about hard mounting a flight controller and not installing a capacitor on mains was a bad one. Not only motors are “twitching” from time to time, a video is very noisy. I hope big low ESR capacitor will solve that, since there is no way for soft mounting for this frame.

Besides that, it worked just fine. I will try to prepare a video from the maiden flight in a few day, for now only a few pictures and final specification:

  • Frame: PLA 3D Printed, 220mm motor-to-motor diagonal
  • Motors: EMAX RS2205S 2300KV
  • ESC: Racestar RS30A BLHeli_S
  • Flight controller: FrSky XSRF3O running Betaflight 3.2
  • VTX: TS5823 200mW
  • Camera: RunCam Swift
  • Total weight, no battery: 380g

Total build is, of course, heavy, but not that heavy as I feared. I was expecting something way above 400g. The frame is also quite stiff. I wonder how much beating it will be able to take….

EXUAV Y120S drone racing frame: go home designer, you are drunk

Chinesium is amazing. Well, to be precise, not only chinesium manufacturers will do anything just to stand off a little. Just like this little (120mm) quadcopter frame called EXUAV Y120S. Why do I even bother to write about it? Simple: I love crazy designs. Just look at those pictures below:

EXUAV Y120S 120mm Mini racing frame

No, it’s not a tricopter. It is a quadcopter. But where is the 4th arm and where 4th motor goes? Below rear motor! It’s a Y with 2 motors on arms in the front and 2 motors on one arm in the back. Rear motors are counter-rotating! Read More
