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:

INAV Airspeed Sensor – which one to choose
INAV flight controllers gives you the option to install airspeed sensor on your airplane, just like in Pixhawk and Ardupilot. And just like in case of Pixhawk and Ardupilot, you have several options in terms of the hardware. Airspeed sensors, also known as Pitot tubes, come in two variants: digital and analog.

How to use INAV Autotune
Autotune is a feature in the INAV flight controller firmware that helps automatically tune PID settings for fixed-wing aircraft. It simplifies the tuning process by adjusting roll, pitch, and yaw rates based on flight behavior. How It Works: Autotune (or Auto Tune) that is present in INAV for quite a long time is a working…

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…

How to connect APM Airspeed Sensor (Pitot Tube) to INAV
Recently released INAV 1.7.2 introduced new hardware support: analog airspeed sensors. I’ve written new but it is new only to INAV. Analog airspeed sensors aka APM Pitot Tubes aka Ardupilot Airspeed Meter and one the market for years. And they are cheap. By cheap, I mean below $30. And until recently they were usable only…

How to connect APM Power Meter to INAV
This topic was eluding me for some time now. It’s time fix the problem and finally present a short tutorial how to connect 90A APM Power Meter for flight controller boards running Betaflight / INAV software and equipped with Current Meter ADC input. I will not show where to connect APM Power Meter to flight…

Using PCA9685 with INAV
The PCA9685 PWM driver working as servo extender is no longer supported in INAV. Use S.BUS output and S.BUS servo extenders instead One of the hardware limitations of flight controllers that usually multirotor users ignores is a number of PWM outputs. To fly a quadcopter you need “only” 4 PWM outputs. Since most FCs have…

How to install and configure Betaflight
Latest Betaflight 3.0 is a new quality for flight controller software. It brings many new, cool, features comparing to previous versions. If you fly mini-quad or micro-quad, you have to check what Betaflight 3 has to offer. This tutorial will show how to install Betaflight 3 and how to configure it so mini-quad can go…

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…
