There's one "feature" that I don't like: When the 550 falls onto its nose, the upper frame plates crush the LiPo. I have dumb-thumbed it twice, and the LiPo replacement easily gets as expensive as all other parts together.
Here's a possible solution. I haven't test-crashed it, but thought I'd take a picture before assembling it:
Three pieces of CF plate, glued / tied together. Those are mounted on top of the LiPo, using cable ties, to the beams that connect upper and lower frame.
In a crash, the narrow upper frame plates will hit the CF plate instead of the LiPo and distribute the force. Or, that is at least the plan...
Edit: Omit the cable ties in the picture, because they'll dent the LiPo :-)
Obviously, a single piece of CF plate would do just as well - if I could find one that big.
And, ideally it would be a bit longer towards the nose.
