I had my PV2 for a week. I upgraded firmware, read a ton, and succesfully flew it 16 times. On the 17th time, I was so convinced of its safety and reliability, I let me 8 year old son fly it. I took off, went to about 80 feet up and 100 feet away, and then let my son fly it... I was talking to spectators, and keeping half an eye on it... Then I heard my son say "DAD".. I looked over and it was in a very fast free fall... not sure if the lights were on and/or if it was upside down... i think it might have been....but definetly coming down VERY fast... either a free fall speed, or upside down, and accelerating down (When i flew it, it was always graceful and <15mph in any direction) it was in GPS MODE, compass calibration had been done several days earlier, and it had a GPS lock with 8 satellites before takeoff... battery was around 90% as it only flew for 60 secs or so.... I got a screen shot from the iphone where the last thing it said was distance n/a altitude 58.7 feet, and speed 39.4mph. (And phantom connection broken in the center) It did come down fast! I beleive the 39mph... My first thought was maybe my son found the special turn off command (left stick down&right, right stick down&left) and maybe he powered it down and it free fell... But then I thought if it was powered off, how could it broadcast it was doing 39mph! it landed in the lagoon, and i didnt try swimming down to get it (20ft deep)... I love this thing and already ordered the PV2+... but now im thinking about liability, and could this happen again? Could this kill someone if it hit them in their head? Does insurance cover a personal liability lawsuit? What happened Anyway? I have a love fear relationship with this thing... Thanks for any comments!
