You want to know how tough these little Hubsan X4 quads are? I was flying one of my favorite H107C quads, red with silver stripes, that I'd made from parts, with no camera. I was practicing, got distracted by a truck coming up the street and lost orientation. When I realized I was pulling hard in the wrong direction it was a little late in the game, so I took her down. After spending an hour where I thought she landed, I was met with a cop who was called by a neighbor who was wondering who was out near his property with a flashlight. He didn't know it was me. The cop understood and I gave up the chase. This was November 24th. I know, because I just checked when I ordered the replacement, which was the next day. A neighbor stopped by to tell me that someone on the opposite street saw some funny lights on the back of a neighbor's roof, so I checked it out and didn't see a thing. Rainstorms came... and I gave up the ghost.. After the worst winter I've ever been through up here in the Northeast with over six feet of snow on the ground I totally forgot about the lost quad. Today, over five months later, I cashed a lottery ticket that I won $5.00 on during our Easter ritual. This caused me to go down the street where that house is. As I rolled on by I noticed something red in the crease of the roof. I did another lap of the neighborhood, parked, got out and got a closer look. There she was. The neighbor graciously allowed me to get a ladder and broom and retrieve her... I got her home (sorry for the incredibly long post, BTW) and pulled the battery for disposal. I then took her apart, blew out all the sand and grit and noted some of the paint had worn and chipped, the screws were a little rusted and the motors weren't quite as shiny, but they all spun by hand. So... I plugged in a battery. Got all the right light sequences. Hmmm... There was one damaged prop, so I replaced it. I put in a new battery, brought it out to the living room, fired it up and flew it around just like nothing happend. The motors sound a little raspy, but it flies exactly the way you'd expect it to... Keep in mind... this is flying around the living room after replacing the battery and one prop.
