Defective 4 in 1?

[Little Green Man]

Hi, I'm new to helis, but have been flying on a simulator for quite some time. I have recently purchased a VNR3D, built a training set out of dowel and have been trying to hover. But, no matter how i set the gyro the tail will still twich uncontrollably I crashed this morning as a result. Any help or ideas would be greatly appreciated.
