It finally happened, been flying my new CX2 for about three months now without a mishap. This evening I was flying outside, it was fairly calm except for the brief little gust of wind that brought my CX2 down. I cut the power to save the gyro and only lost the tip of one of the upper blades. I replaced the the upper blade and now I have a wobble or vibration when I power up. Once I get the CX2 in the air in flies very normal. It's just when I start the initial power up and before lift off that the helicopter shakes intensely. What should I look for and where should I start looking? Or, don't worry about in and just get it into the air and fly?

Is it tough to tear down the head assembly, this is my first?
Thanks everyone for your help.
