I have a mixed bag. I currently have 4 T-motor U8s and 4 T-motor U10s. I got a really good deal on the U10s on ebay from a seller who actually had 12(the perfect amount for a quadruped) but I hesitated on buying the whole lot. At $80 a piece I probably should have just done it. I’ll continue to look for deals in the mean time.
Yes this is great that these are so close to the same size. When I first read your post form my phone I thought these were the 5000 series smaller multistars. I am about to get into Fusion360 and see how these might fit up.
Do you have any plans yet for how you are going to implement any of the impedance control for the joints?
