Well, given how well the other m models have been holding up, there is a good chance the mCPx will too. Depends on what the blades are made of. Both my mCX and mSR have hit walls, floors, ceilings, drapes, furniture and ceilings fans, with very little damage, so here's hoping the mCPx does too.
Last night I finally had to replace my upper blades on my mCX, the little pin for the flybar link broke after its 30somethingeth crash. The other side pin broke off a long time ago, after the first 30somethingeth crash. So far after several hours of flight, I have had to replace the inner shaft, and the upper blades. By this time with my Cricket, it was beyond repair.
Edit, just for kicks I did a google on the Cricket, Someone still had one flying.
