I see the 501X hingepin is 48.5mm. I assume the Durga one is too. The TA-05 one is 49.7mm. They are the same width and same material. On the tourers (TA04, TA05), they are the weak point and we like it that way because you almost never need to replace the arms (not that the arms are not strong, the carbon reinforced versions are about unbreakable). The tourer hingepins are cheap to replace and we can get them easy here from the Tamiya shop.
Also, I'm sure they bend more easily on the buggy than on the tourer because the buggy arms are longer and a crash with the buggy puts more force on the hingepin than a crash with the tourer.
If it really is a big problem, you could try to make your own hingepin out of "dowel pins". Don't ask me what they are but I've seen them at my nuts and bolts supply store, they are dirt cheap, come in all shapes and sizes and they are hella strong, so I use them in my custom projects. Only, they usually are some form of steel that can rust a bit over time and they are usually a little bigger diameter than they claim to be. You might need to turn down their diameters just an itsy bitsy teeny weeny bit. I don't have a lathe, so my makeshift way is with a Dremel and cutting disk like so...
