I'm a newbie and have been flying my 3DR quad for a few weeks now. I saw the impressive post about Arducopter 2.0.55 and decided to try it out tonight, so I fired up the APM Planner selected 2.0.55 and installed it. But afterwards all of the settings relating to my RC and sensors were lost. So I went through and reconfigured it.
Here's my question: is the software upgrade process for an end user documented anywhere in the arducopter manual?
I proceed with my upgrade in the way that I thought made sense, but I wasn't really sure what I was up to. And then after test flying, I started thinking that I might need to update the gains, but I wasn't sure how the default gains are set and whether I should be needing to update them right after an install.
