For one, you are not very versed in what QWW offers for the machines they sell. Actually, I will help you understand more about them.
The spindle and head assembly your referring to is a specialized head that was made available for the PRO type machines many years ago. It had alot of adjustable means and was geared for more stable F3C type of flying at the time. I never liked it either, I hate the design of that head, but that doesnt mean it does not do what was intended.
Now, they use on most machines, and exclusively on the bat series, a sport head with stiffer damping. QWW did look into it, and thats why this head is used now, with some updates now. A one piece feathering shaft (do not have measurements, but its huge and strong. John or Chris or Irwin can provide that), as all machines do today. In fact, the head used in the BAT series are virtually IDENTICAL in diameter on all parts, including the grip bolts to my Avant. You can use 4mm or 5mm blade bolts. I used 5mm for my Vblade 690's. I used this head in my Dominator 70. Only real difference is the Avant is a tad more refined in adjustments and can be programmed, and maybe a bit more robust in the hub, but the geometry and design is the same, as is the same on the MA Stratus and Vibe 50. Look harder and you will notice the same. This head is robust and strong as hell. I am not BSing anyone. Its is as good a rotor head as many, and can be changed through damper and shims as all other. I will say, the QWW Shaft system and sport heads are very good. I never had a problem with them.

I dont fly for QWW, and I dont speak for them. I would still be flying the QWW machines, but my reasons for not doing so have nothing to do with the product, so face it, but facts are facts. Its important to know facts before you post.
Hope this helped, BillieBob
