5.8GHz FPV channel frequency table
For 5.8GHz FPV systems, there are 5 main bands divided into 8 channels each. That gives 40 channels free to use. So, in theory, 40 pilots should be able to fly FPV at the same time. Unfortunately, this is not true. First of all, there are transmitters, and there are transmitters. Better, properly tuned, will…

How to flash MW OSD to Micro MinimOSD
While playing with newly arrived Micro MinimOSD and attempting to flash it with latest MW OSD software, I’ve discovered that offical tutorial, as well as many other are missing one tiny detail that makes whole process much harder than expected. In theory, MinimOSD just Arduino Pro Mini with additional hardware. So, in theory, you plug in…

Let’s build a FPV drone: motors and electronics
My 250 class quadcopter project is slowly coming to a successful (hopefully) end. Finally had some time to assemble motors and ESC. Since I wanted to have rather standard setup with 5×3 propellers, I had no super high demand on ESC, I’ve decided to use Turnigy Multistar 10A V2 ESC preflashed with BLHeli software available at Hobby King.…

Let’s build a FPV drone: frame assembly
Yesterday I finaly had some time to work on my 250 class quadcopter based on ZMR250 carbon fiber frame. There was a plan to finish it before weekend, but looks like plan will have to be changed. I’m missing motor screws. They were not with frame nor motors. Too bad… After one evening of work…

Adding GPS to Flip32+ and Cleanflight
Flip32 and Flip32+ (10 DOF version of Flip32 with built-in barometer and magnetometer) are nice little flight controllers. And cheap. Some call them clones of Naze32, but this is not completely true. Yes, they are very similar, share the same hardware, but they are not identical. I would say they are better than Naze32 since have…

Let’s build a FPV drone: frame
Many say that small 250 class quadcopter are super fun. Small, fast, agile, tough and crash resistant. I’ve decided to check it out and build 250 quadcopter drone by myself. And next few posts will be tightly connected with this topic. Let’s call it a build log. The most important part of every multirotor is a frame.…

Depron RC Plane Build – Everything You Need to Know
How hard it is to build a RC plane without plans and starter kits? To do it in “Trust me, I’m an engineer” style. In mid June I’ve decided to give it a try and right now I can tell: it’s hard, but not that hard as one might imagine. All the problems I’ve faced…

x525 V3 Quadcopter Frame Review
There are many cheap quadcopter frames on market. Big, small, X, H, foldable, good and bad. And choosing a correct frame for a purpose is both hard and critical for further drone performance. One of cheap, and on a first glance, versatile frames, is x525 V3. Is it worth the money? Well, it’s a hard…

Dead Rat, wooden quadcopter, maiden flight
Last week I was, finally, able to perform a maiden flight of my DIY wooden quadcopter (here and here). I will not say it was huge success, but it was a success alright. What went like expected? Well, quite alot. First of all, it flies and has enough thrust to weight ratio to do flips…
