Hey guys! Last Saturday we shot a few car scenes in the Swiss Alps. Everything went fine until the very last scene. Immediately after take-off our Alta 6 banked hard to the right and crashed into a bush. Luckily it was close to the ground (which ultimately is applicable for most crashes ) and other than a broken landing gear and 2 damaged propellers nothing happened. Our pilot is convinced that it wasn't a wind gust that blew the Alta into the bush. He also claims that his right stick inputs (Pitch/Roll) had no effect on the copter's behavior. He was only able to control the thrust with the left stick. Take-off was in manual mode. A cell phone and an additional radio were used to communicate with the driver. Could these devices have created some sort of interference between the Futaba remote controller and the Alta? I'm a Mac user and have no access to a PC that fulfills the system requirements for the data viewer. I tried to analyze the flight logs in Excel but unfortunately I just can't make any sense of it. Can any of you flight log wizards please help me analyze the data? We have an important job coming up and I would like to have the assurance that it's safe to fly. Here's the link to the log file. I uploaded the last two files just to make sure. The one that recorded the crash should be SYNLog-13-11-22 https://www.dropbox.com/sh/8fcoxn70nha0v6j/AADms5p4pkfPi8A10AT3c7VLa?dl=0 Many thanks!
