Note: just as the release was going out an issue was found re support for the all Camera Gimbals on the APM1s (it doesn't work) and with 3 axis gimbals on the APM2 (2-axis works ok but not 3). If you're one of these people, please wait for 2.7.3 which will be out shortly.
UPDATE: 2.7.3 is now in the Mission Planner
Functional Improvements over 2.7.1:
As per usual PIDs are optimised for the 3DR/Jdrones quad with 850 motors and 10" props. If you're using more powerful motors/props and are seeing bad flight behaviour in stabilize, start by turning down Rate Roll P in 25% steps.
There is still some question on whether the default Roll/Pitch Rate P (0.175) is high enough (it was 0.185 in 2.7.1) and also some people feel the Throttle Rate should be higher (currently 0.300 but some say 0.330 or even much higher would be better).
Please feel free to report issues you find in the discussion below and/or add them to the issues list.
Thanks and enjoy!
I have attached a few log files. Looking into rerouting power to the motors, cleaning up the installation, looking in to metal work, etc, as well.
Well, it's been a while since I've hijacked a thread, and since I am currently very happy with APM and 2.7.4 and the upcoming fixes I thought I'd go way off topic, just to keep you entertained...
Although I suppose it is on topic cause next time I'm swapping the naza for an apm :)
Leave it escape, you have it poor beast locked in four walls
Is anyone else having problems assigning channels for gimbal servos.? I'm using apm2 and the latest code from the mission planner.
I'm don't want to use channels 10 and 11 as i believe they are limited to 50hz whilst all the other channels will go to 490hz(hope this is right?)
Anyway i've tried changing them from the gimbal set-up page and the parameters list, but the servos only work when they are assigned to 10 and 11! (and seem very slow)
Any help would be much appreciated, i want to use high speed digital servos on my new quad http://ecilop.tv/shop/ecilop_easy.phtml
It's an interesting design I've got high hopes for, i recommend a look!
Thanks all, looking forward to flying this new code!
Very interesting design, using the battery to counterbalance the camera. But that looks like an awful lot of mass for a servo to handle.
Muse/madness - good stuff for this type of footage.. :)
Christian would you please post your dataflash .log file for this flight. Thanks
Where do I get this?
Didn't want to start a new thread for this as it's a very basic question, but what is the variable used inside ArduCopter to find the current roll angel?
The one that shows as 'roll' under APM Planner.
(Also is there an easy way for me to determine what the variable names are inside the ArduCopter code based off their description is in the APM Planner (i.e. somehow seeing the APM Planner code to determine what they are calling to find the value)?
This type of cardan must use two independent gyroscopes for better result.
Standard upgrade balance PTZ,with 2 axis Gyro structure,(needn't control by flight control board,1 single axis gyro or dual axis gyro is ok
Dave I read that the best is the top motors spin at 93% of the bottom motors. This was taken from and extensive study NASA did in the 60 to 70 on coaxial prop affect. What I did was use 800kv motors on top and 880kv on the bottom. It did seem to work better.
