Hi All, I'm considering attaching an old iPhone 3GS with a PAYG SIM to act as a GPS tracker to my Vision Plus in case the unthinkable happens and I get a flyaway. Whilst I am taking all the precautions to ensure a flyaway doesn't happen, it's always at the back of my mind making me very nervous as I really don't want to loose close to £1k... (wife would kill me!!) I could use things like Find Friends, Find my iPhone, or some GPS tracking app that runs in the background (know of any good apps?). So, does anyone have any suggestions on how best to attach an iPhone to the quadcopter itself? From my playing with different locations, it seems to fit best just under the battery as it shouldn't get in the way much there. However I need something strong enough to hold it in place but easily releasable so I can remove the battery... thoughts? Would velcro be strong enough? I'd also need to attach velcro to the iPhone so I'm not worried about using super glue if necessary. All suggestions welcome. Thanks!
