Presets for larger multirotors

[RCnator]

Current Behavior

Currently there is only presets for quads up to 7 inch.

Desired Behavior

Since I guess the name Inav stands autonomous flight maybe there should be presets for larger quads and not only racing size quads. In my case 15 inch.

Suggested Solution

Maybe add presets from 9 inch with 3 inch increments up to 18?

Who does this impact? Who is this for?

Quad and multirotor users, all skill levels.

Additional context

+1 on this.
I believe iNav 5 had a preset for 10" which was a fine starting point for everything big and slow, but they removed it in iNav 6. Additionally, it seems to me that they have changed the PID controller logic/sensitivity in iNav 6. I flashed iNav 6 yesterday, migrated the iNav 5 settings that flew fine and crashed upon take off by flipping over. The thrust graph for that "flight" looks like god damn saw teeth. My PIDs are 90 34 54 - basically the old defaults.

You’re more than welcome to suggest actual settings that work with a range of different quad at those safe settings.

Unfortunately I myself lack the skill and know how to do that but hopefully someone else picks up the ball.

Agreed, we need a safe settings for wide range of quads.

I would like to leave my +1 here. I just added a 10" to my fleet and I'm having a very hard time trying to make it work. It oscillates a lot. The funny thing is that I used inav 2.51 IIRC in a very large quad and worked quite well.

I currently try to find the best PID's for my 14-inch Quad. Seems not that easy in INAV6.
This 14-incher is an old one which I was flying with a DJI-Naza controller in the early days.
Now I switched this Quad to a Matek H743 and the tuning work begins again.

I can see Inav 7 is out now but there is no mentioning of improvements regarding this issue unfortunately.

No one has put forward any suggested setups. AFAIK, no developers have quads over 7”. As already stated, someone with larger quads will need to make suggested settings which are tested by the community and work on a wide range of quads with the target prop size.

TBH, there just doesn’t seem to be that much interest. Maybe start a conversation on the INAV discord’s multi-rotor channel?

[MrD-RC]

I created the discussion on Discord. https://discord.com/channels/791437907478577172/1173188186382549032

[petrweigl]

is there some progress on this issue?

[MrD-RC]

There had been no preset recommendations. Also not a lot of interest on Discord. It seems like most people don’t fly quads that size.

I have quadcopter with 12inch props running on inav7, trying to tune it. I am getting poor performance … with my settings.

A lot of us dont have a discord account, see above, and dont want to open up yet another online account, especially when we already have github.

For Inav to live up to its name I think there should be a bit more focus on larger multirotors rather than racing quads, but I also remember when we were contested requesting dshot, [https://github.com//issues/1489]

[MrD-RC]

The problem is there is simply not enough interest. And the INAV pilots who actually have these larger quads aren’t coming up with any suggestions for settings. These settings will need to work for a large range of quads in that size category.

So without any suggestions for settings, which are then tested by the community. The profiles cannot be added. If you guys with 10” quads want a preset. I’m sorry, but you’ll need to put in the legwork, experiment with the tunes, share findings with others to help come up with the settings. Without that. The presets you want won’t happen. The ball is in your court guys.

I’m going to convert this to a discussion. As that is now more fitting.

+1 on this. I have a quad with TBS Discovery frame 2213 935kv Motor 10" Props. Previously I was using Pixhawk flight controller and it was stable and smooth, now I am running Inav 7 but am not able to tune it. It oscillates too much I have been trying to tune it for the last couple of days but have not been able to. 🥲🥲 No luck.

I compiled nav 2.4.0 installed it on the board and applied the default 10" preset it's pretty much more stable and more flyable.

Only problem with quads from 7 inch are vibrations. But my drons fly indoor for testing from 7 up to 16 inch. They are very stable. You need to know what you doing. Vibrations, filters, PID. Use Inav blackox log and pidtoolox. Drons from 7 inch are hard to tune. Some nice starting PID 55 75 35, if vibrations are not huge go for 60 75 40. Gyro filters in my 16 inch in 50hz all tuned in Inav 7.1. On the drons from 7 inch my flight controlers are in some 3d printed box. Moving air is so big. Why n3 and a3 have fc in box?. Good starting point for 10 inch is 7 inch setup from pawel only lower filters by 10hz. My fc its not on esc like you see aio tower... Its solo down centre of drone. Esc is back or upper frome fc. Thats how need to by and if you want to fly big dron you will need 3d printed parts. Or buy a3 or pixhavk

Setup: Tarot 650 quadcopter, FC kakute f405 with inav 7.1.2., esc mamba 4in1 50a, motors 4114 400kv 16 inch prop. For testing I use 4s batteri 5200mah
Tarot frame was moded to lower vibrations:
3d printed links from motor to motor( 4 links) PLA
ESC is back and fc is lower the centre in 3d printed box. I use TPU 85 infill 100% for box
tpu dampers on motors and screws
My log file is here if someone help: Need some tune for PID but fly is good and stable indoor propwash test
blackbox_log_2024-09-12_115002.TXT

next project is 10 inch full printed and fly like 7 inch... I will add log for that BEAST. Project was 1 year old but i will update all and post logs.... Matek f722se, 35a esc, 10 inch props, fully printed only hands aluminium... compas with gps bn880
In this setup esc is up and fc down centre isolated. In all my project i use overkill of 2 1000 35v capacitors
