That's it for my S400... I just broke the upper servo saver arm (401048) and this was the last piece I had in my spare parts box (I had 3 before). This is for sure I could not find a replacement part even with the other kits. I've been running my S400 with 2 of the wheels' 5x10x3 BB (which is very hard to find) even close to binding.
Guys in this forum have been trying to keep the S400 alive with a few ways or so. Time to move on guys. I will be shelving my S400 until something from the manufacturer will come up (if any). Will try to concentrate on the T2R Pro which I got 2 months back or anything - anything but Serpent...
Sorry guys, it hurts me as much as it hurts you...
So, how about a 21 gun salute to the S400... rest in pieces.
