Building Possibly My Last Multicopter
I left the hobby in 2022 after the crash of my Tarot Ironman due to a propeller blade separation resulting in complete destruction of the aircraft. Since then I have been flying an old DJI MAvic Pro that I bought used from a photographer who wanted to upgrade. Anyway, recently l've thought about wanting to build one more multicopter. I enjoyed the challenges of building one plus the satisfaction of flying something I built. So I decided to once again embark on a build project. My needs…

Take a look at the "AC3.1 & blown 3.3V regulator" blog post to understand the issue of the blown 3.3V regulator and how AC3.1 uncovered the issue. This information should also help you zero in on identifying whether this is actually what happened to your hardware.
@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.
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.
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

Thank you all; I have making some progress towards my project while reading your inputs

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.
