So, apparently I was in someone else's thread and fudding things up so from now I will post all questions in this thread.
I have completed the build minus a stripped screw head.. I'm using Hudy allen wrenches that are pretty new and they should be of good quality. I think the problem was the screw hole was not perfectly lined up when I tried to tighten it and stripped the head. Well, I got it out with a polygrip so now I need to replace it somehow. It's one of the longer back ones that secure the bottom plate and tail boom support rods.
When that is done I move on to 3gx setup. Before I start I want to make sure I run the right software. I have to download it and the first question is about the version. Do I need a specific version for my 3gx or is it best to download the latest one?
Also, do I reverse the servos and swash functions before i plug the 3gx into the computer?
