Version 2.4 of the ArduCopter code is now available in the AP Mission Planner and in the downloads area. Although not as big a change as the 2.3 release, it still includes a respectable number of enhancements and bug fixes.
The default PIDs are optimized for a 3DR/Jdrones quad with 850 motors and 10" props. If you're using more powerful motors/props, start by turning down Rate Roll P in 25% steps.
Thanks go to the numerous contributors including users and their detailed bug reports, developers and testers. Hopefully all together this will add up to a nice smooth release!
As per usual, please post your comments, issues in this discussion. For enhancement requests for future versions, feel free to add them to the issues list. Note: you can "star" an issue to receive emails when someone comments on the item. On the dev side it helps us because we can get an idea as to which feature requests are the most popular by sorting by the number of people how have starred each issue.
I think matters will be improved greatly in 2.4.2, but for now, are you tuning nav_P with channel 6? That seems to have the most effect on loiter of late, that and dropping your rate_p to about half what you consider normal for your frame.
No... Loiter_P with ch6... and 20% changes to Nav_P from 2.0 to 8.0
I can wait.. This happens a lot.. The Dev team will figure it out I am sure... They have done a
great job... I have done simular things with a boat but what they are doing is not easy.. !!
update... just flew 15min... tuned Nav_P from 2 to 8... would not stay in 100x200 foot field or would overshoot and increase oscillations..
Alt hold was oscilation up and down 1-2 feet slowly... which is fine by me... It could hover at 6 feet no problem... fantastic.
Is it possible to have the Mission Planner have a pop up window that shows what was updated after each time we do an update ? This will save as trawling through all the forum ect to find what was done.
Thanks John, but a pop up summary would be nice to right.
Yep, you re right- it would be nice. Especially for those who rely on the Planner for updates.
What we're trying to do for the recent releases is put all the major changes that we think people will care about in the blog. So above you can see the list of Enhancements and bug fixes. I guess you think it's not complete enough? It's true that we didn't clarify in the blog post what was changed between 2.4 and 2.4.1.
Hi Randy - which blog? I started looking through the blogs pages, but it was not obvious. A link would be a great help. Tx, Bill
the thing is Randy that the Mission Planner gets an update around 2 to 3 time per week. But unless we dig around to find it and go through each and every file on the source list page we have no idea whats been done or if the copter firmware has been altered as well. It might sound lazy, but it makes me hesitate every time I see the MP popping up an update and whether to accept installing it before reading the forum to see what was done.
Seeing there is a pop up window there in any case why not then add the text to it with just a brief summary what changes it will make?
Here a new video of a LOITER test flight in windy conditions (13 Km/h from S-O) with the beta Acducopter v2.4.2b firmware (with the latest Jason's fix) currently under test in the AC dev Team. There was a small drift due to the wind because I have set a too much low Integral on the Loiter. The quadcopter was really reactive Vs the gusts and very stable as you will notice in the video.
Very nice JL! so this fix is basically going to be in the official 2.4.2 release once it comes out?
Sorry for the repeat question but there have been many posts and I got confused: Can you please also confirm that loiter is now contrelled by the loiter params independently from Nav(but obviously in general dependant on Stab params)?
