INAV for tracked rovers and tanks
INAV 2.5 introduced rover and boat support. However, INAV setup on tracked vehicles like tanks or with differential steering was never really working like expected. Turning was possible but only in forward or backward movement – throttle had to be not-idle. And that meant that turning in place was not an option. Luckily, the INAV…

Bidirectional DSHOT & RPM Filtering – Is It Really Necessary?
There is a group of people who think that the RPM Filter is the best thing to happen to flight controllers and quadcopters since the sliced bread. Perhaps. I’m more inclined to believe that RPM Filter is just an example of good functionality. But it will not be about that, so let’s go back to…

ZOHD Drift Review – a smart FPV glider
Airplanes are fun, and I like to fly them. Unfortunately, most RC airplanes have a severe flaw: they are big, bulky, and traveling with an FPV airplane can be a pain in a posterior. Sure, some can be disassembled into a few smaller parts, but usually, those parts are not small, and assembling the airplane…

I will not discuss if the EmuFlight Kalman works and how it works (it works tho, I have enough time in…

How to setup INAV on a rover
INAV finally allowed to use INAV and INAV compatible flight controllers to be used on rovers and boats. Finally, INAV supports not only flying vehicles. Bear in mind, that the rover and boat support is not full, and some functionalities might not be working like expected. What works:

Ritewing Mini Drak Center of Gravity
Ritewing Mini Drak is a fantastic R/C airplane. Fast, stable, and thanks to smooth lines and negative swept wing, it looks great. Thanks to negative wing sweep and a long nose, it has a very unusual center of gravity (CG). Mini Drak’s CG is located almost at the leading edge of wings. The Center of…
