What are Motor Stop and Airmode features in INAV and how they differ from each other when used on multirotors and fixed-wing airplnes? Should you use Motor Stop on multirotor? Should you use Airmode on a fixed wing? Long story short:
On multirotors, Motor Stop not recommended to use while Airmode is recommended to use. More than that, you can not use them both at the same time, since they exclude each other!
On fixed wing aircrafts Motor Stop and Airmode are highly advised to use together.
I like my 7-inch endurance quadcopter. It might not be the fastest one. Or the smoothest one. But it gives quite a lot of fun when just cruising with interesting views. And, since the battery lasts for more than 10 minutes, you can have this fun for a long, long time
INAV 2.0 changes a lot. Including OSD. One of the new functions is something called "OSD Profiles". You can set up 3 independent OSD layouts to radio switches and change them during flight. One OSD profile can display all the data, second one minimal set of data and the third one Map or Radar mode.
The common cranes (Grus grus) in a middle of the video really could not decide if they are scared of my drone or nor. In the end, I've decided to leave them alone… Storks are usually more friendly. They tend to ignore drones at all. The locals call this place The Carpathia. Why? Perhaps because those are the only "hills" on a completely flat area around.
INAV 2.0: Wind estimator. What does it do? Tries to estimate the speed of the wind (obviously) as well as wind direction. Let's be honest, it's experimental and relays only on the difference of predicted and actual flight path. So do not even try to think it will give accurate measures. But my tries says that wind estimator results are plausible as long as an airplane is stable in the air.
With INAV 2.0 you have an awesome OSD font called Vision. It's designed with readability in mind. Looks awesome, works awesome, has super nice graphical touches! From my perspective, the INAV Vision OSD font is the best font out there.
Autotune (or Auto Tune) that is present in INAV for quite a long time is a working solution for tuning PID (or rather PIFF) controller used by INAV on fixed wings (all airplanes, flying wings). Not like all the attempts designed for multirotors, this one actually works.
INAV Autotune can be used on any airplane and is fairly simple to use as long as you follow a few simple steps:
I’ve been asked to cover this topic multiple times. So, welcome to part one: how to connect HC-SR04 sonar rangefinder to INAV and any flight controller? The answer is simple: don’t. HC-SR04 sonar is absolutely not suited to work on a drone! It picks noise instead of ground echo and above a certain altitude (low altitude by the way) reports rubbish! From time to time it kind of work over concrete but immediately loose measurement capabilities over grass.
This is one of the most frequently reported things about every new version of INAV Configurator: from time to time, it starts minimized and it can not be made visible. It is a bugger connected with a fact that INAV Configurator does not have an installer. It's just "download and run" and after releasing a new version, we can not delete stored data during install. Since there is no install process.
This is one of the most useful INAV functions for fixed wings! Servo autotrim solves the problem of trimming the airplane for level flight. Yes, flight controller does is “automatically” in stabilized flight modes, but for good Manual flight performance, you just have to have trimmed control surfaces. A long time ago you had to use some tricks and “adjustments” but for quite some time, INAV can do trimming for you.
Hey, don't leave yet, there is more!
Do you know that there is a YouTube channel with awesome, drone and FPV related video? Why don't you give it a try?
