Nah, I did not experience that. The plane shown above was / is basically rock-solid... it's just all robotic parts slowly moving out of the place where I put them. I was so excited about them, but this - and one other bug - really renders them completely unusable to me.
The other bug: If you lock a piston on neither fully extended nor completely retracted and lock it (e.g. cause it is completely overloaded otherwise), save/load the game or switch to another craft or whatever, the piston comes back FULLY extended and locked. Since it does not fit into the position it had before, it is sticking out everywhere and the craft is nicely destroyed.
