Version 2.5 of the ArduCopter code is now available in the AP Mission Planner and in the downloads area!
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.
While some testers have reported very good flights with the default PIDs, some have reported that this release is a little "sharper" due to the DCM improvements and have found they needed to:
reduce stabilize P by 10% (i.e. 4.5 -> 4.2)
reduce stabilize D by 30% (i.e. 0.15 -> 0.10)
increase rate D from 0 to 0.001
Tuning loiter can be tricky. Refer to the discussions which will appear below for more community feedback on what parameters work best.
Please post your feedback in this discussion. For enhancement requests and bug report, please add them to the arducopter issues list. When possible please include logs (tlog and/or dataflash) and tell us whether you're using APM1 or APM2 and what version of the software you're using (presumably 2.5 but tell us anyway!).
Thanks for this release go to the developers (both in the core team but also those who have provided bug fixes through the issues list) and also the community members who participated in the previous release thread and provided some great detailed information in the form of issue reports and logs which allowed us to nail some bugs!
i have seen it and i did do a LIVE data calibration just before i flew it today. it didnt seem to work well though. ill give it another shot. thanks.
I would like to compile the latest version of the ArduCopter by myself using Linux/Ubuntu, but it doesn't work (have an out of range error while compiling).
Actually it works well using the Mission Planner to load the pre-compiled code, but I would like to enable the piezo buzzer support.
Any idea ? Thanks - and congratulation for the ArduPilot !
excellent position hold in light breeze!
Todd: Nice one! Is that APM 1 or 2? Any special PID settings?
Care to post your param file and setup? That is a great loiter!
That's a nice looking quad! How much does it weigh?
what you see without the gopro is .98kg.
Thanks for posting. Very nice looking quad and lightweight to boot! What motors are those? They look efficient :)
Very nice :)
