Most likely the tail motor is shot.

I thinks it started after he crash it. I replace some parts included the tail motor because the tail tube was bent.

Well, the tail motor pushes the heli cw, to counter the ccw rotation caused by the torque of the head. So, ccw rotation means the tail motor isn't working right. It's not turning at all, it's turning too slow, it's turning backwards, etc. Could be a bad motor, wires reversed, damaged board. DH models have very poor QC, so anything is possible.

I agree with the poor QC. And the tail motor is turning too slow. Thought I give it one more shot with the board before I call it quit .

Even if it was working perfectly, it handles very poorly because it has no channel to handle roll. So, it's no great loss.

I think he would do OK with a WL Toys V911 or V912. The V912 is bigger, but wears out motors on regular basis. If you don't mind spending more, the Blade Nano QX quad is a ton of fun.

Is the tail prop on backwards? The airfoil works much better in one direction than the other.

No, the shaft on the tail rotor gear is hex.
