Nano CP S problem swash plate forward solution

This video demonstrates a solution to swash plate forward problem.

However, prior to the crash I still experience some other issues, such as:
1. Drifting (for example, to the left or right)
2. Wobble and twitching at times during flight when I start flying aggressively.

Here is a link to the other Nano CP S video I created:

Again, on YouTube I have seen many people have success with this Nano CP S. I have also read online that some people are Not have success with this helicopter and experiencing one or more of the same problems I experience. So, I guess somewhere along the manufacturing process, something is going wrong that affects the quality of these helicopters.
