So, you want to build your own RC radio system? Long range maybe? Cool, I want to do it too. Since I’m pretty deep in that topic now, I can give you a hint or two. For example, have you thought about a protocol your radio system will implement? Or rather should I say: protocols?…

Since I just started to add support for “old” FrSky XSRF3O flight controller to INAV (expect this in a release after 1.8) it might be a good idea to share few words about it. First of all, it comes in a box. Why am I mentioning this? Because none of my flight controllers, and I…

Looks like crappy range problem from previous post is fixed now. Today I managed to reach 2.8km range with better antennas. The ones I got from LoRa32u4 supplier were NOT 868MHz antennas for sure! 2.4GHz/5GHz probably, hard to tell. Traces on PCB are ~60mm long, so perhaps those are loaded 3/2 monopoles for 2.4GHz or…

This will be fairly short entry. Do you know what E45-TTL-100 LoRa wireless serial modules were missing? They were missing configuration tool for other platforms than Windows. And even on Windows it had some minor problems. Luckily, this has changed only a few hours ago. Stronnag, the man behind mwptools mission planner and tools for…

More than 2 months after previous “What it the most popular flight controller for INAV“, welcome to second edition. I mportant, this is not the number of boards flashed with INAV, but rather number of times a board was connected to Configurator! This counts TARGET software name, not retail name. For example, all clones of…

I will be very honest: until very recently I did not really understood how PID controller’s Dterm really works. Yes, something with dampening, something with “looking into future”, bla bla bla. But the reason for not understanding was because I was overthinking it. There is no “magic” only simple mathematics and few basic concepts which…

In this episode of “Gyroscope and filtering” I show you how to configure notch filters using Betaflight Configurator and INAV Configurator software. Previous episodes: Episode #1 Episode #2 Episode #3

I just finished first test flights with laser rangefinder VL53L0X and well, I’m disappointed. Before I will show any data, let’s review test conditions: VL53L0X configured for Long range mode: 2m 8PM, obscured sky, no direct sunlight Over concrete And it looks like this: Solid readout ended at more less 80cm. Above that, valid readout…

Let’s say I have almost a good news about sonar support in INAV: yesterday I flew terrain following mode with experimental INAV code. And did not crashed when shooting video below. I did crashed next code version, but that is only a minor detail, right? When shooting that video I did not touched throttle stick.…
