@John McGrath and others. I am curious about the regulator that has been mentioned. Do you have a location on the board or schematic? I ask because I bought a used APM 2.5 and have had issues with it concerning updating to 3.1. I'd like to replace mine and see what my results are.

Comment by John McGrath on January 7, 2014 at 2:14pm

Guys if you have a bad regulator why not fix it? Most are all DIY types on here get a soldering iron (low wattage) and replace it then get the better update. If mine was blown thats what I would do.

So i went back and installed 2.9b and the same thing occurred bad gyro health prearm health bad on the flight data page and i cannot arm the ESC's funny it all worked prior to updating to 3.1 is there a way to fix it ? not going to purchase another APM any help appreciated.

Hi Sean 

 Yes i see that this is a common problem after updating to 3.1 i would think that 3dr would take care of the issue guess not. 

Thanks for the information i am going to try and go back to previous 2.9

I had the same problem, likely a blown regulator. seems a pretty common problem. In the "load Firmware" section of mission planner there is an  option at the lower right side that says "load previous firmware" or "load previous version" . You can find version 2.9 there.

Comment by Dennis Fuente on January 7, 2014 at 12:14pm

hey guys 

Is it possible to go backwards in version say from 3.1 back to 2.9 my apm worked in 2.9 but came up with a problem in 3.1.

Thanks

@essam

You may have a look at this French site : http://airinov.fr/concept#/concept/télédétection

They are using 4 different lenses of which 2 different IR, specifically to do exacftly what you are looking for.

You may use Google automatic translation if you cannot read French.

@Essam: ArduCopter has no trouble at all climbing to 2200 AGL; in fact, it can get there very quickly.... the limiting factors here is regulatory and one of resolution and of vibration. As you are in the US, you'll need to stay under 400ft AGL. Being closer helps in that each pixel of your camera will cover a smaller bit of your target, meaning that it is generally more useful. It also means that whatever blur effect you have from high frequency vibration is a bit less destructive to the data, as long as it is within acceptable limits.

What is the reason you need to capture the entire area in a single shot (vs taking multiple shots in rapid succession using a patterned flight and stitching them together?) There are a growing number of software packages that stitch the photos together for you....
