Ok,
Such a small benefit isn’t worth it here. This is just a test aircraft. Better to save processor capacity.
I’ll post my test logs here tomorrow hopefully!

Sadly enough it has been raining here all day so tests have to wait.
Hopefully tomorrow I will bebable to do the testflights

looking forward to your update
Do you have the latest test results?
Sorry, it’s been raining here the past days, I’ll try and get some flights in today if possible.
All good Axel, you can only do what you can do. We appreciate your help!!

I was able to fly and gather at least some data. I had to make it bit quicker than I initially thought since it’s still some rain in the air. I put some tape over the ports on the cube and went anyways, worked out nicely since there was so little rain.
Here is the 4.2.3 flight:

Here is the 4.3.0 flight:

It felt like it flew better on 4.2.3 than on 4.3.0. Don’t know it if that’s actually how it is but maybe you could take a look at that when you look over the logs, maybe some filter thing or PID thing, should not be PID though since all is same but it might just be me overthinking.

We (mostly Leonard and Tridge) have a number of bug fixes and enhancements that we hope will resolve the internal errors and control issues caused by overloaded CPUs here and in other threads (discussion1, discussion2).
Below are links to firmwares for a few different boards. In each download are two firmwares, the “432rc1” firmware includes simpler bug fixes while the “432rc1-withdt” additionally includes Leonard’s control timing improvements. I’m happy to pre-build firmwares for other boards upon request.
FYI @Axel1, @xfacta, @A_manafi, @TilCreator, @kalai1219

Hi Axel,
Thanks for all your help with this problem. I think we have fixed a range of issues and the binaries that Randy link to will improve the handling of these problems dramatically.
Both of your longs are very similar with just a little more load on 4.3 as we expect. I am not seeing anything to suggest that 4.2 is flying better than 4.3 now you have backed off the load. However, have a look at the binaries that Randy links too and see if you feel any improvement there if you have time.

Hi,
I’ve experienced a minor incident so I’m waiting on some new propellers.
No issue with my vehicle, just with me, was over 2 years ago since I had an incident so I feel kind of dumb now…
Although I will test the new firmware (the one with the new controllers) once I get my new propellers and have conducted a full hardware inspection on my craft. Everything seems fine so I’ll probably be able to test as soon as I get propellers, but I haven’t done all the system and hardware tests yet so might have to swap something more…
Thanks!

On another note, I’m trying to learn as much as possible about tuning and I just wanted to ask you if you got a log from a perfectly tuned aircraft I could look at as a benchmark for good tuning.
I know you work with this and that you won’t be able to just post logs for vehicles you build but if you have any log you can post It would be appreaciated!
I might be able to help with that. I’ve got a couple of logs of different sized quads I can send to you
I PM’ed you a couple of links and photos

@Axel1, just curious, in your original post you mentioned that takeoffs were ‘sporty’:
“My quad makes like a jump into the air. I raise the throttle slowly like I always do.”
I believe you ultimately concluded that this was not an issue in your use case, but I’m curious if addressing the internal errors helped mitigate it, or if it is just characteristic of 4.3.x?
I also noticed this when I switched to 4.3.0 on a Orange Cube; it was inconsistent, but compared to 4.1.5, it was startling. I experimented briefly with the TKOFF_SLEW_TIME, but did not observe any change in behavior. While it isn’t problematic on smaller aircraft, doing a full-power ‘send’ for the first couple feet of takeoff on a big ship would be… Terrifying, haha!

Hi Luke,
I did experience the jumpy takeoff and still do on 4.3.0. I haven’t tested 4.3.1 yet so don’t know if it’s still there. It did go away and came back each time I switched between 4.2.3 and 4.3.0 during my testing. Currently, I’m on 4.2.3 and don’t experience the jump on takeoff. Although I will soon test the 4.3.2 firmware including Leonards new control loop mechanics.
I came to the conclusion that it’s an intended maneuver done by the drone to get some height right after takeoff. I thought it might had something to do with the slew parameter since it was the only new parameter listed regarding takeoff, but I might have been wrong.
Maybe @rmackay9 knows if there has been any changes that would result in this, and if there is any parameter to make it smoother again.
You could make a new post about it if you want to discuss it with the developers. I bet all feedback regarding new flight behavior is welcome, and maybe others also have some feedback to give as well.
@Luke_Ionno and @Axel1
Could you post logs and observations about the takeoff behaviour in 4.3 here so I can go over the logs and see if there are any issues or if I can help you.

Hi Leonard,
I’m sorry for the delays, I’m still waiting for parts…
I’ll get to testing as soon as I’m in the air again. If the testing is still relevant than.
I haven’t forgot about it!!!
Version 4.3.3 fixes this problem.
I’ve finally got it flying again.
Although, it might not be needed to test this anymore. I think I saw your new control loop management integrated recently.
I’m happy to help in the future though!
