Lipo fires are no fun, even for a battery as small as the mCX's.
As well-engineered, but minimal as this heli already is, I would not be for chopping out ANY bracing or support on it, anywhere. On the huge metal helis, sure they do have extra junk, and might be hugely overbuilt, but this thing is already so 'optimized' and light, that I would not want to remove any part that might be needed to contribute to structural integrity.
Again the grommet-on-the-pin fix seems to me to be a pretty darn good fix, and with minimal downside - the slight possibility of losing your skids, only if they are too loose and you also fail to put some adhesive on them.
