The legs!! I hate that design. Not everybody takes of and lands on flat land. Sometimes I have a real problem finding a perfectly flat spot to land on. From old ingrained habits I always take off into and land into the wind. I have had a couple of times where she tipped over backwards. No damage yet but it has to be hard on those motors to stop that fast. There is no reason they can't design a UAV with a wide stance and solve that problem. That is why I will be looking hard at the EVO or the new Mavic. I am going to steel my nerves and learn to hand catch, but in the meantime I took a 3/16 carbon rod and taped it with black electricians tape to the bottom of the legs to prevent it from tipping over backwards. I cut the rod so I have 3 1/4 out the back and close to 1 1/2 out the front the legs don't get into the video this way. It works very well. I had to cut some slots in my case for the legs to fit.
