I'm with xyster101 on the plastic swash. I don't know why some have persistent problems, others have no issues at all. I broke a ball off one of mine after falling out of the sky onto pavement. It simply landed wrong. My CX is so old that when I got it the CX2 hadn't been invented yet. This is my second plastic swash - no issues.
0I wonder if the swash problem is part of the deal where guys move the linkage to the outermost hole on the servo arm. I'd guess that the servo is fully extended at the time of impact (in attempt to avoid the collision) and the stress of the servo push added to the collision is what breaks the swash. I left my servo links in the stock locations and removed weight from the flybar for a bit more performance.

A lot of guys loose the lower head in favor of the alloy. What breaks is the larger drive posts that drive the lower rotor blades. When one of those breaks off, measure the hole in the blade, find a little piece of wire (I use aluminum wire) that fits nicely into the hole in the blade, drill out the broken stub in the hub and stuff the wire piece into the hole. Reinstall the blades and fly. I did that once. A long time ago.

I did find the Skids and Boom from Boomtown Hobbies to be a goldmine. Goldmine from the perspective of spending less on parts. And the skids protect the helicopter frame and battery tray as the skids are really flexy and tough. They work like bumpers when you mess up.

I also did get the upper alloy bearing holder and bearing. That's the one that centers the inner shaft in the outer shaft at the top of the outer shaft just below the upper rotor. The stock bearing cup will wear out and go off center causing wobble at the top end. You don't want a wobbly flybar. When you get one, you'll be back here asking what TBE is.

I may catch a lot of flack for this, but when you feel the need for something else to play with, you may consider a fixed pitch. There are a bunch of fixed pitch helicopters out there and most are really similar. I hear the Esky radio gear is better than most. Anyhow, the fp helis are really durable and a blast to mess with. You'll probably get to the point where you will fly it around the yard when there is very little wind. You won't do a lot of fast flight, although there are you tube videos showing a fixed pitch helicopter doing things I didn't think possible. And they cost about half what a coaxial costs. There are very few parts to the helicopter and most are very durable. A crash that would cost two or three blades on a CX will cost nothing to repair the fp. Don't try to get too serious with the fp, but they are a really cool little helicopter.

That's just my opinion.
