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!
Check the Wiki, its the best thing since sliced bread!, I have a CC, and just got a couple of Naze32 FC's and I miss the PID tuning via radio
Jason: you can tune ArduCopter PIDs via regular telemetry radio with the MP, and also tune certain parameters via CH7.
Yes Chris, I was referring to the other FCs which you cant tune via radio :)
Today gloomy Sunday in Auvergne (France) with the wind (15km / h)but I could not resist to fly my new quad: Avionics:
- DJI framework
880-kv motor, ESC 40 A propeller 10 * 4.5, apM1 (Software 2.5.4),Sonar 1200, Lipo Battery 11.1v 2200mA total weight in flight 1400g
the initial parameters are
I Stabilizes test: very good
halt hold: not very satisfactory
I joined the newspaper, if an expert could get PID a'aider in settings ..it would be nice ..!
Good day and good flight
I cant connect my APM2 via CLI... strange code only?!? Connection and config via Mission Planner
I try to erase the APM for the Update but CLI doesnt work ;-(
Are you hitting Enter three times in the Terminal screen to get the CLI menu? The "strange characters" are just the usual MAVlink binary.
i hit Enter three times... no CLI menu
Chris: I just tested (ArduCopter 2.5.4, MP 1.1.73) and it works fine. Are using the latest version of the software?
At last, a day off! Spent a good few hours and many milliamps getting to know 2.6b (same flight control as 2.5.4)
The following vid is done on a 3dr frame, standard 850 ardu kit, APM 1. Sonar enabled.
I did a lot of tuning today, I'm getting great results, next day off work I have I'll have cracked it I think. But for the video I stuck to stock params, (actually i had set stab_D and stab_I to zero. and was using rate_D of 0.08 and rate_i 0.8. Similar effects, i just prefer using the rates for my flying style/objectives) But the main difference is reducing loiter_P to 1.2.
Hey Dave, have you got a pic of how/where you have your gopro mounted?
