It was my understanding that once you take the plunge to 1.5 you can't go back. I feel like I have been had I did the upgrade and now I'm having transmission issues. I'm grounded as far as the app is concerned. I didn't want to upgrade but one day my RC upgraded so I thought that meant I have to upgrade the craft to 1.5. I did read people who were happy with 1.5 but I'm having nothing but issues. Install said success so not sure whats going on. Never had issues with this craft before and was counting myself lucky when I would read others horror stories well now I have mine unfortunately.
