  @ 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?

  @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.

  Vote of confidence for NEO-M8N??? If you are using one can you say it's been solid / trouble free? Better than the 7? I lost a quad last summer. Fly way. Never found it so I'll never know but I had a M8N on it at the time. I'd like to put one on my new quad I do like how fast it gets 10 sats or more!  But I sure would like to here people say they haven't had any issues them first. Thx

  What have people found to be the most efficient forward speed for mapping on a 3DR Y6?

  Please stop the misinformation.

  2200kv with a 6s will kill a 30a/40a ESC.Also, weight of quad impacts flight time..... Slower KV larger propellers is more efficient. Battery capacity influences flight time and somehow you estimate flight time without this variable..... So please just stop. 

  Please use a calculator sch as http://www.ecalc.ch/

  Battery voltage, KV, Propeller size are all contributing factors. Voltage can be anywhere from 3 - 50v. 

  2200kv..... I would never recommend this speed of motor on multirotor unless using 2S.... But your discharge requirements on the LIPO are going to severely  limit thrust.

  2200kv @ 30A will but it depends on the motor and props for lift..
  2200kv is usually a small profile motor for about a max of 8 inch props and at that wattage 2 or 3 cell you are looking around sort of 15 mins flight time on a quad or tri.
