PPM signal support for FS-i6 radio
FlySky FS-i6 (or branded Turnigy TGY-i6) is a very decent 6 channel entry level RC radio system. But support for PPM (CPPM) standard is somehow not clear. I have no idea why manufacturer keeps PPM support data so well hidden. Anyway, here it is: how can I enable PPM on i6 radio system? PPM signal…

PWM, PPM, and Serial RX explained
When speaking about radio systems for remote controlled models, multirotor, airplanes, gliders, there are some shortcuts that might be unknown for beginners. Those are: PWM, PPM, Serial RX, S.Bus. Today I will explain basic concepts behind them, and when they are used. PWM PWM, as Pulse Width Modulation, is something a standard for controlling different…

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…
