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'm sorry Harrison, unfortunately these things can happen, but too often when something is wrong (defective APM2 or other, imho).
There is a more or less reliable, it is until it crashes.
I personally have tried Naza and is not that great, there are systems that work better and cost less.
Last week a friend has dropped over 3000$ of material with an Octo Mikrokopter.
The most users flies with APM2 and has all these problems.
Sure, there are always things to improve and we are working on this right direction.
Good luck with Naza! :-)
Marco, you mention that there are systems that work better than "Naza" and cost less. Can you
be more specific and tell me which systems please? Also what problems did you experiance
with Naza? Thank you.
Rabbit Flight Controller... and of course, APM2 with the latest fix (unreleased at the moment).
My colleague just purchased a Wookong Multi. He is attempting to get a guide to basic settings (their equivalent to PID) but has been unable to speak to a US Wookong representative. We have both scoured the internet attempting to find anyone who can help him with no results. If you are expecting better support, you might have an unpleasant surprise. I wish you luck with DJI (which, BTW, makes a great product in their high end controllers). I do not know how the Naza differs but I would think it is similar to the Wookong M.
Contrast that with this community. It is rare that a question or problem goes more than a few hours before someone steps up to help.
APM2 has had a few problems, but I have never seen a community better equipped than this one and which will step up to solve those problems in a very short time. When I received my board, it would load the software but would not verify the load. 3DR immediately issued an RMA and is reimbursing me for the shipping charges. Incidentally, no problems were found and the problem appears related to the fact that I am using a Windows 7 Virtual Machine running inside of Mac Snow Leopard because I do not own any Windows based computers. I still have to resolve that problem locally,
Considering the capabilities of APM2 at a price point that is one sixth that of the Wookong M, I am more than willing to deal with any problems because I know they will get fixed in short order by a very talented and conscientious team. That said, you can be sure I won't be putting my 5D Mark II up in the air until the current problem is resolved, but I remain faithful that it will soon be resolved.
Help!, Out of the box default PID's except Rate Roll Ive tweaked it down, flying stabilize mode, I cant seem to get a stable hover, its hunting up and down and is constantly needing throttle input, In the past Ive had to add in the config file # define INSTANT_PWM ENABLED(which I dont need todo now)just to get my ESC's to arm, Ive flown alot better with 2.49 and below, nothing has changed in my setup or my approach to loading new code(via MP), I have a feeling it could be my ESC's are not 'fast enough', Im flying a heavish Hexa with latest code
Has something changed that is causing my ESC's to power up and down?
Im running APM 1 1280, Turnigy Trust 45amp ESC's and Turnigy SK3536-910kv motors
Im really scratching my head on this one!
What's your THR_RATE_P?
Try .450, that helped me
Ill give it a go, My hexa is hunting without touching the throttle even if I do get it into a hover, Its almost like its on alt hold but it isnt
Jason, I believe you have a lot of power for the default PIDs. I'm on a quad with 2218 motors 30amp esc 930kv and I had to lower THR_RATE_P to 0.225, but this setting will affect you only on auto modes if I'm correct. Your problem must be with RATE and STAB P terms. Try to lower RATE_P to 0.070 and STAB P to 3.000. The best thing, if you can, would be to use ch6 (in air tuning) to tune this settings. Start by tunning RATE P wich is the most important, give min and max tunning values 50 to 150 (that will translate to 0.05 to 0.150) start from the lower and increase it slowly, when you feel oscilations it means it's too high, lower it to a confortable value. Put STAB and RATE I and D terms at 0 before you do this, since first you want it to fly reasonably stable, then, the other params can be tunned properlly.
