Mine did the same thing, there is a fix for it. All you have to do is turn down the gain ever so slightly. I started with it not holding the tail then turned the gain up to much to where it would skip as you are saying at a slight turn, I found the perfect in between after serveral adjustments. Make the adjustmensts in real small increments and unhook the battery after each adjustment.

As for the other post on mono-coating the blades great Idea as well as the 30 minute epoxy. I just took the covering off mine and put some trim decal on the ends to hold the weights on. I like both ideas though. I really wish they would make some carbon fiber flat blades for it though.
