I think the big technical draw here (at least for me) is their DPE (Digital Position Encoder). Unlike a traditional analog potentiometer, these servos track their position digitally. You know how some servos can start stuttering when they get old? That’s usually due to the pot going bad, and the servo trying to “correct itself”, looking for the appropriate pot value to do so. In theory, that won’t happen to these. Being digital, I believe you can also adjust the overall end-to-end throw on these using the Hotwire app - that is, if I read the information correctly.

I also happen to be looking at Tekin servos for my Nitro TC (and Tekin ESC’s and motors in general for my electric cars), so I’m quite interested in what others have to say about them.
