Okay, well first, welcome to the forum!

Second, you have WAY too much going on there. The rule of thumb for upgrades and mods is to only do one at a time. That way, if something goes wrong, you know exactly wheer to look.

Third, what do you mean by shaking side to side? Give us a better description, or, better yet, a video clip if you are able.

Fourth, you can fly around just fine with your canopy off. I do this all of the time when I am setting up, tweaking settings, etc. I only put the canopy back on when everyhing is dialed-in.

Fifth, any unbalance from fore to aft is most likely caused by improper positioning of your LiPo pack. Think about what you just did. You just added a bunch of weight.. to where? The front of the Heli! You will want to counteract this imbalance in the COG by moving your LiPo pack aft towards the tail.

Go back to stock and see what happens. If the shaking is gone, then you know it was one of the upgrades. Put one thing on at a time and put her in the air again. Come back with specific questions and you will get all the help you need. There are lots of experienced pilots on this forum.
