PID looptime: why it is not only about frequency
Last 18 months was an extremely good period of time for all mini-quad enthusiasts. Progress, hardware and software both, was just incredible. Who could have guessed that in less than 2 years mini-quads will evolve into main group of drones with such excellent flight characteristics. Just take a look at looptime. When I entered the…

Tip: how to secure XT60 plugs
I had a problem with my FPV goggles: I was constantly breaking battery cable near XT-60 plug. One not careful enough grip and cable was ripped away. I’ve decided to fix it and permanently secure the cable with epoxy glue. Sure, I could use hot glue (that looks ugly) or Sugru (that is expensive), but…

How to measure gyro noise frequency with Blackbox
Betaflight (and INAV) lowpass filter tuning can be a hard thing to do if you have not idea what is noise frequency you want to cancel. Sure, you can blind test or read tutorials. But what if I tell you, you can measure it quite precisely using only Blackbox logs? Or measure rotation speed of…

Air Crash Investigation: gone in 6 seconds
“What goes up, must come down”. I had an opportunity to face this old truth 2 weeks ago, when my 600mm quadcopter felt from 30 meters straight into water. It was supposed to be a simple flight: take off fly few hundred meters away with GPS assist engage Return To Home and land Dozens of…

PWM, OneShot125, OneShot42, Multishot and DSHOT comparison
Two years ago it was simple: you wanted to connect ESC to a Flight Controller or radio receiver, you were just doing it. There were only one (maybe 2) protocols that allowed to pass information to ESC. It was a standard PWM protocol. And it was enough. No, with faster hardware, mini or even micro…

How to tune PID I-term on a FPV drone
With this entry I want to initiate short series of articles showing how to tune multirotor / quadcopter PID controller. Let’s call it a continuation of Blackbox series, but this time I will not relay only on Blackbox data. Yes, I will show few examples how given scenarios looks on Blackbox logs, but all steps…
