    1. My HS720E went wild and broke the right front arm. I ordered one and it came today. Is there any place on the internet that tells how to replace that arm?
      I had used it four times and it operated fine. The fifth time when I hit the unlock button, it took off sideways and ended up crashing into the hill. I don’t know what happened but I had no control at all. If you have any suggestion as to what happened, I would appreciate any information you can give. I have had the drome only ;two weeks and that is a lot to pay and it goes wild in that short of a time. This isn’t speaking very well for the product. Please advise what I need to do to fix it.
