Hi all- I was looking forward to some footage of the Woodward Ave DreamCruise in Michigan this past weekend-- so I practiced at the location for about a week in advance, and set up all the shots. Unfortunately, the day of the event-- I launched the Karma just like normal and it immediately went into BOOH (Bat Out Of Hell) mode-- flew at over max speed up and away, and out of sight. I regained control for a moment and coaxed it back halfway-- before it went BOOH again and flew about a 1 1/2 miles away and landed at Divine Faith Church -- hitting a tree and dropping to the ground. GoPro India provided me with this location, after updating my logs-- and they were right on... so I did recover everything, and what appeared to be only 2 broken blades. Unfortunately now, I'm getting the dreaded Fail to Launch-- contact support... even though everything seems to be working-- I replaced the 2 blades, the stabalizer is working fine in the handle and will pan the camera on the ground. Recalibrated everything with no errors. Any ideas??? It's a bummer that this things gives zero feedback to what is going on.... GoPro has been OK so far, but I've been having to call them back and lately all they want me to do is the same stuff over and over. Is there a bad batch of stabalizers? My drone was shipped originally in Feb 17.... so pretty early. I just never used it much-- Sorry so long--- bummed about having something that such a simpleton error... with no way to troubleshoot.
