I received my PV2+ back from repair (flex ribbon & new wiring harness) last Monday and took it out for it's first flight today. I went up to a mountain area (Bear Mtn for those of you in NJ/NY). It was really windy and I couldn't find any (read: zero) GPS satellites after trying to calibrate in two locations in a valley. Figuring that poor GPS reception was probably to be expected in that terrain, I decided to take it up to a lookout point that I know of that was at much higher elevation thinking that, maybe, I could get reception there. No dice. However when I took it out of its case and set it up, I drew a crowd. People were asking questions, wanting to take pictures and video, etc so I obliged and told them that due to the wind an my lack of GPS, I wouldn't be launching it but that I'd turn the props on so they could see. All was normal until I went to turn the props off. i pulled both sticks down and toward the center of the remote (as I always do) and instead of turning off, the propellers accelerated to what sounded like full throttle. Strangely, the phantom didn't lift off. Instead, it tipped over (propellers still going full-speed) the camera came off the gimbal and the flex ribbon got severed. My main goal is trying to figure out what could have gone wrong. The control was on, neither of the switches were thrown (putting it in RTH mode), WiFi signal was good...everything was completely normal until I tried to shut the props off. Luckily, the copter didn't lift off and hit one of the many people gathered around it in the face! I've been trying to connect both the phantom and the remote to my laptop (macbook pro running osx 10.9.5 "Mavericks). No matter what I do, the laptop won't see the phantom or the remote when connected via usb. Something seems really messed up and I'm trying to sort it out and hoping maybe some of you can help me shed some light on what could have happened this afternoon and what I can do to get my laptop to see the connected devices?
