How to use INAV Autotrim function – since you should do it
INAV Autotrim is a feature in the INAV flight controller firmware that helps automatically adjust servo midpoints for fixed-wing aircraft. It ensures that the control surfaces are properly trimmed for level flight, making manual mode transitions smoother. This is one of the most useful INAV functions for fixed wings! Servo autotrim solves the problem of…

ZOHD Nano Talon FPV Airplane, part 2
After a maiden, I’m not very happy… Nano Talon is quiet, efficient and small. But flight performance is not overwhelming. Even quite far good. Let’s say it’s OK. But the worst thing is that I crashed mine due to hardware failure. ZOHD, where is quality control? This should not happen.

DIY Dipole for Crossfire and FrSky R9M
Details for halfwave dipole for an 868MHz band are quite simple: two 0.8mm copper wires (used for welding) cut to 77mm and solder to the end of coax cable. Here I’ve used RG178 put that thing into a 3D printed casing put antenna tubes around wires. I got mine from here: http://bit.ly/2vHHqDk glue everything together…

DIY Moxon antenna for TBS Crossfire and FrSky R9M
Moxon antenna in layman terms, it’s probably a simplest linearly polarized directional antenna. It’s like a bent halfwave dipole with a bent reflector in a back. Think about it as a very simplified Yagi antenna. It does not have much gain but has very good backward rejection. And thank’s to a simplicity, Moxon is super…

INAV Braking Mode for multirotors
Flying with a multirotor drone with INAV always had a problem: braking. When you were flying fast and then release the stick, a drone was not braking very fast, then it was going back to the place where you released the sticks. Rubberbanding. Irritating. Over the time there were at least 2 attempts to fix…

Betalight 3.3 and Kalman filter (BiQuad+FIR2 to be precise) situation
Betaflight 3.3 RC1 Betaflight is at the end of next release cycle. Betaflight 3.3 RC1 has been released only 2 days ago and that brought us a (not) Kalman filter! Long story short: Raceflight was using Kalman (Fast Kalman Filter – FKF) RS2K left RF and brought FKF to Betalight Betaflight did some changes and…

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…
