I just got my smartech Exquiste. I tried to fly it and it gets off the ground great but after about three to four seconds in the air it starts to vibrate and it gets so bad the main blades start hitting the rotor blades in a hover. Any suggestions on how to fix the problem or what is wrong.

check ur head assembly and see how everything fits; u might need to sand and trip some parts. Just get a good look at it. Hope this helps.
