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!
thanks for feed back Crasher. What do you mean by 500m limit? When I look at it Ive already spent EUR6k for a couple of rigs that still aren't 100% good for UAV using the APM systems. I don't mind tinkering with them and do enjoy it, but for my friend who just wants a rig that fly's for his aerial business this DJI seems the way to go. He is fully non geek so likely easier for him to. What are your copter specs your using for the DJI?
I thought the full UAV upgrade for DJI was more like $7000?
And have they solved all their GPS problems yet?
Personally, I'd rather have a system that isn't precise, but never loses GPS lock (APM) vs. a system that is super precise, lets you fly missions far away, and then suddenly loses GPS lock and just goes into manual mode.... if you're beyond visual range, now what?
It seems that DJI has finally fixed the GPS bug: http://www.rcgroups.com/forums/showthread.php?t=1628068&page=50
This is what I found and the cost is about 3k all up for the UAV AP. although I'm not sure the difference from way point one and the latest way point 5. Probably software? http://www.atlantahobby.com/Store/pc/WooKong-WK-M-Single-Waypoint-K... I assume with this you would get the full operating firmware and software? I do a bit more research and think Ill give this a go and see how compares
hey all!!! just flipped my big new SteadiDrone octo, not as in flipped and crashed, I mean looped :) Will post video soon.
NICE! I don't think I am brave enough to attempt that with my 5.5ft diameter octo ;-)
LOL - cmon Adam, you can't tell us you have a 5.5ft Octo and not show us any pics! And video!
That'd be somethin' to be seen ;-)
it is quite something to see..........
I have yaw burst issue. When i fly with stab mode hexa can make 360 degree yaw without touching any sticks.
