You might find that spreading the hinge plates wider on the tread shoes will
help. Having them near the centre increases the "twisting" effect if there are
forces near the edge of the shoes. Also, having 3 per shoe instead of 2 may help
- mine don't break apart very often now, mostly only when trying to turn (move
one tread faster than the other).

Perhaps switching to 2x plates instead of 4x for the tread surfaces would help -
this would help to smooth the curve around the wheels, at the cost of almost
doubling the number of hinges you would need to add.
Otherwise, love this MOC. Great follow-through on your initial inspiration.

good idea,I have a lot of hinge plates in my depot. So I will give a try.

Yes the 4x plates are really "stressed" turning around the wheels.
I think the combination of both, smaller plates and re-arangeing the hinge
plates will result in a mutch stronger and more flexibel tread.

Thanks a lot. Since I saw J5 in the movie the first time (and this is many years
ago..) I wanted to build a copy of him.
