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…

Troubleshoothing INAV: magnetometer/compass is not working
A magnetometer is a sensor that measures the strength and direction of magnetic fields. In drones, magnetometers are used for navigation to determine geographical direction and allow precise position hold when stationary Your magnetometer/compass is not working with INAV? Is the sensor red in Configurator? You are not the only one… Not only most popular…

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…

Omnibus F7 Flight Controller
I got my hands on a new STM32 F7 flight controller: Omnibus F7. Before we proceed, small note. I am a huge fan of F7 flight controllers. In a year, they will be a main line of high performance FC on the market. STM32F7 with built-in UART inverters solves so many issues STM32 F4 boards…

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…
