I'm flying a phantom 3 advanced with version 1.3.20 and haven't upgraded to 1.4.0010 yet mainly because I'm so happy to finally have stable and reliable firmware. I know 1.4.0010 has the Intelligent flight modes, but their implementation appears to fall short. Is the newest firmware 1.4.0010 as reliable as 1.3.20 and how does it effect range? Im sure this has been addressed in the forum already, but I couldn't find it this morning. Thanks for the help.
