Question about 3 Important Parameters

Hi friends!I'm doing an experiment with APM and I need to know the order of magnitude of these parameters: 1. Noise of accelerometer and gyros. 2. Time delay between sending a waypoint to autopilot…Continue

Has anyone made a pdf or some other printable version of the Arducopter/Arduplane manuals?  I would like to print a manual for reference, or at the very least have an offline copy of it.  All my flights our out of cell coverage.  And when my laptop is running Mission Planner, I don't want to be switching back and forth between it and a browser.

Screenshot%202015-04-10%2012.49.42.pngHello everybody,

few days ago I've downloaded the "Mission Planner" update. After that, when I plan a new mission and set up new waypoint with the "green" selction button (please see the screenshot eclosed), the waypoint is automatically positioned in a so far location distance. Anybody knows the reason why? Many Thanks

I have a 2013 3drobotics quad I would like to mount a gimbal, does anyone have a simple mount process. I would like to use a canon 260 for video

@ Doug

I have not tried sonar / LIDAR yet.  That all seems to be a grey area ... I have a feeling the devs are deep in some secluded room working on  these details as we speak. I am really interested how that optical flow works. I will be trying to land on a boat. If it's drifting around a bit can it see the boat move and stay with it? Seems like it should. Can't wait until these things are worked into the code.

@Richard, @Kennedy,

I curious if Sonar/LIDAR corrects altitude in Auto?  Has anyone tested to see if these sensors correct as you are flying over various terrains?

Comment by Richard Kennedy on March 3, 2015 at 6:14am

@Darrell

I think the devs are working on the ability to use known topography data for just such an instance but as of right now I think you have to do in manually like you are doing. Or you could use a sonar device like these. I'm not sure how well it works I never tried it myself. http://copter.ardupilot.com/wiki/common-optional-hardware/common-ra...

I'd like to do a fairly standard lawnmower pattern over an area of trees to do some mapping. There is quite a slope from one end to the other. I thought that I'd add extra way points and then adjust then increase the altitude as it goes up the hill so I have a fixed height over the trees. I just wanted to check that there isn't an easier way then this before I gave it a try. Any ideas on keeping the height relative to the sloping landscape rather than just a fixed value of the barometer? TIA

I have an issue with my Arducopter in Auto mode. Can anyone help?

I raised the question here: http://diydrones.com/forum/topics/arducopter-gps-failure-with-low-h...

I have NEO-M8N from CSGshop. Plug-n-play after verifying settings. I normally get 17-23 satellites and 1-1.2 hdop within 15-30 seconds, depending on cloud conditions, K-Index doesn't seem to affect it nearly as much.  With the 6, some days I couldn't fly because hdop wouldn't drop below 2.5 or <10 satellites, or even glitch after takeoff....yikes.

No negative issues yet, only orders of magnitude more confidence I will fly when powering up.
