Words cannot describe the feeling the first time you flip a switch and your plane then comes back to you. What once was pure science fiction is now a very affordable reality. To perform these feats, we use INAV modes to define how what happens to the model. This article provides you with details of the INAV modes and also guidance to which modes you may want to use.
When you installed your flight controller you wanted to use all 16 channels and install all the INAV modes all at once.
But keep in mind that some of these modes surrender some if not all control of the plane. Thus, you can very realistically watch your plane fly away never to return. So be selective in what you wish to include. INAV in a fixed wing plane brings a multitude of possibilities.
After that we have the fully autonomous flight INAV modes. But all these features need some knowledge to be able to use correctly. Firstly, we will explain, how every INAV mode works by itself. Then, in the second part, we will explain their dependencies and preconditions.
The following INAV modes are flight modes.
OpenTX Arming Warning System for iNav
Flight modes do not fly the plane for you. They are generally used to assist you piloting the plane. Manual, formerly known as Pass through, the pilot has direct control over the servos.
You can fly, as if the model basically just has a receiver, without any input from the flight controller. No mixing on the transmitter is necessary. When setting up a new plane, you should be manually trim using the Manual mode. Particularly in the case that anything is wrong with your setup, sensor failures, bad PIFF values, unstable flight behaviour. This will allow you to bring the model home, albeit without stabilisation.
Some people even prefer to fly in manual, because it feels more natural. So INAV will always try to keep the current attitude of the plane when the pilot has no stick input. As in most flight modes, the flight controller takes over the complete control of the servos. This is known as rate control. There will be more on setting the rates in the Tuning Guide.
Troubleshooting INAV: why INAV is not arming
In angle mode, the control method changes from rate control to angle control. Therefore, with no stick input, the plane will always fly level. With a stick input for roll or pitch, the flight controller will change the angle as a result of the stick movement.
However, at maximum stick movement, the plane will pitch or roll only as far as set in the firmware. There is no automatic control of altitude and throttle, so the Pilot still needs to be in control of that. The yaw axis is still in a rate-controlled mode and only stabilised. Horizon mode is very similar to Angle mode. The difference is that when the sticks reach a set stick input threshold; horizon will automatically transition to rate control.
This allows the pilot to do rolls and loops. But the plane will return to angle control once the stick is below this threshold. Navigation mode also include some autonomy in the flight.E learn cyber
Navigation modes are all based on the Angle flight mode.Published by Mr. In INAV version 2. This new feature is a simple but powerful addition and often overlooked. What it does is allow you to set an altitude for when you reach your home position that is different to the altitude that the model will fly back at.

This system works by taking the control of arming away from a simple switch. For this tutorial, I have a arm switch on SF towards you is disarmedlaunch mode on SD centre positionand auto tune on SG towards you is enabled.
I will use channel 5 to send the arm state to the flight controller. I have also separated blocks in the logical switches and special functions to make it easier to understand. These blocks can be put together so long as you adjust the logical switch numbers appropriately. We will get started nice and simply with the arm state variable.
This keeps track of whether the system is armed or not. There are 3 options for the arm state:.Classico bianco luci 3 thessa stile lampadario provenzale
The next step is to create the logic for the tests. This is a test which will be performed every time the arm switch is thrown. This system uses an arming state to monitor and decide how to work.Cracked account checker
The only thing the switch SF does is inform the system that you want to arm, and disarm. Which means there is a switch in the wrong place, stopping the system from arming.
The final thing we need to do, is tie the system together with some special functions. These set the arm state and give feedback if any tests fail.iNav Configurator Arming Problem
The final section is for the alerts. This should give you a working system that performs tests before arming the model, and alerts you to what is stopping arming from taking place.Not sure what to buy? Pawel Thanks for uploading this video — it will be a very useful check when sorting arming problems My arming problem occurred when setting up a fixed wing — it was due to a non-compatible ESC I switched to a different ESC and the problem was solved regards Hans.
Thank you for a very useful video. I would like to more about arming problem s for fixed wing models as well. Good video. Are you running sonar now?React usereducer pattern
Is it now working, and with which device please? Thank you. You said you are ready to arm at the end of it but navigation is safe was in red how come? I have this problem with my omnibus f3 board. I cant get that nav is safe in green.
I only test my hardware its all on the bench and the only things I have on it is RX ppm for testing TX outputs. This is all fine. But if I want to simulate arming with switch it wont let me. Navigation is safe never goes green what ever I tried. Is this because I do not have usb and motor connected or should it work without it?
Maybe I have stupid question but this is first time I am doing this. Pawel I have followed all your videos and have put them into iNav and I still cannot get the board to Arm.
Pawel, given that I have an issue with the aileron and rudder throws in HORIZON mode, and you explained that that is because the Integral will not be active if the controller is not active, I grabbed an extra controller, and configured it without GPS nor barometer, nor compass or magnetometer disabled them in the Configuration, and the UART port.
I am running iNav 1. Now, with that said, I cannot get a green in the Setup tab on the navigation safe. Therefore, the question is, if we are forced to have a GPS connected to be able to activate the controller. Otherwise, which other situation would block the navigation safe, considering that I am not using navigation? Estou usando Spracer F3 — inav 1.
Hi friend, good evening I follow your channel and I decided to mount a drone, but I have a big problem when I set and I put in Alt Hold mode and nav Hold the drone oscillates a lot and turns over and falls. I do not know what else to do. Please help me, I do not know what else to do, in case I can send you the Blackbox file for you to analyze. Why not change Inav so it is like pixhawk.
The last line of the status info is arming prevention flags list:. Notes: Refer to the table below for the detailed flags meaning. Arming prevention flags in status command works only from BF version 3.
If your craft has a beeper connected to the flight controller it will emit a warning signal indicating the most important lowest number reason why arming is disabled. For example:. You can see the arming prevention flags right on your OSD screen. Notice that it will only show the most important one.
This is the same value as the beeper indicates in the case of the arming prevention. Parts of this article taken from Betaflight Wiki History: article created updated table to betaflight 4. I am getting arm codes 17 and My arming switch is a 3-position switch and it shows, and in the receiver tab. Any ideas? My T12 shows 4 bar, the FC blue led is flashing all the time and when i power up it beeps 5 times.
In iNav the receiver page has all channels shown but still does not change with stick or switch. I watched a couple of your vids on flags and but still cannot fix this problem. Thanks again for any any help with this problem.I will also explain the common problems that prevent a mini quad from arming with Betaflight. If you are completely new to Betaflight, check out my tutorials on how to setup it up for the first time. This will let you know what is stopping arming.
This will indicate the issues that are preventing you from arming. If you have access to a computer, you can easily check the Arming Disable Flag in the Setup Tab in the Betaflight configurator. The last line of the status info is arming prevention flags list. This feature was made available after Betaflight 3.
Quadcopter Doesn’t Arm? Let’s Fix it!
The beeping pattern can be broken down into:. Each long beep represents 5, while each short beep represents 1. Once you have found the arming disable flag numbers or names, you can look it up in the table below to see what they actually mean. Try to go through the following check list.
Maybe your mini quad is not on a level enough surface, or the ACC accelerometer is not calibrated. When CPU load is too high, the flight controller will simply refuse to arm.
Ideally every channel including throttle should have endpoints of and If they are not then you might want to calibrate your radio endpoints first. Try setting it to or even I hope that was helpful!
If you are still having problems arming your quad after following this guide, please post your question on our forumI am more than happy to help. Hi my quad isnt arming, the motors dont spin but i get a response from the motor tab and i get input on the receiver tab when im moving the sticks but it doesnt spin the motors and only one motor just twitches and nothing else happens.
I typed in status and there werent any flags.The following is information pertaining to your flight controller. So if you have problems not allowing you to get the plane ready for maiden, or if an issue creeps up after many successful flights. Check the Setup page for pre-arming errors.
INAV is wonderful because the red flags clearly tell you where the source of your problems are. If there is any other errors this is also where to start investigating. Check ARM status at the top of the Configutator when connected: Triangle sign needs to be yellow, chute symbol grey and chain symbol blue.
If you see these three things, then it is armed. Still no motor reaction? If you have a prop it will likely spin. Still not working? Is the GPS symbol in the top bar blue? If yes, cabling is fine and you should go outside to test again. However, if it is red, check your cabling first. Got to the GPS page and look for the value for Total messages. If this number is going up, the GPS is working, you should try outside or near a window.
Still no luck? If the port is correct, try different BAUD rates. Default is Try to lower it step by step and always Save and Reboot. Still no link to the GPS module? Most likely defective GPS unit or incompatible, try another one. Firstly, check for correct binding and connection;see your receivers manual. You will need to confirm a binding light is on. Then go to here. Is the correct Receiver Port selected in the Ports page?
Is the cabling is correct according to the FC manual? Check at least 3 times before you continue! Go here. Continue here. Check the receiver manual.
PWM is obsolete these days unless you have a very special FC that supports one wire per channel connection. Omnibus often has an SBus tab that you need to solder. Check the Receiver tab. Is it working? When you move the sticks are you seeing the bars change on the screen? If the input is there but strange, we cover this in the next section.
It does depend on your receiver and on your transmitter settings what channel is used for channel RSSI and if it is active at all. If the channel order is wrong, you will find that moving a stick on your transmitter moves the wrong bar in the Receivers page. So to resolve this, change the Channel order via drop down list and see if one fits.
