Here two pictures from all MG996R servo’s and All CS238MG servo’s, to see the difference in the total weights.
The CS238MG servo’s saving a 161 gram of weight and they are placed more closer to the elbow !
Both are a positive part, to safe a lot of friction to all arm and shoulder servo’s

For the CS238MG it was necessary to redesign a simple ServoBed.
See picture….
This ServoBed is without any sensor options, it’s just for now to test the mechanical performance.
And to see which options I can include to give it a smooth run 🙂

I hope to show more this day….
