The V5 S652 (revised Arrma) servo is no better than the old ADS15M. Specs are overrated in their retail marketed published specs. They Claim max. torque 18kg at 7.4 volts. Which at first glance appears higher than the analog ADS15M (15kg). But the v5 RTR rigs BEC can only can operate at 6v with the new Firma 150amp ESC anyway. That brings actual torque down to 15kg if even that. Published Specs don't talk about torque at 6v. It would probably be embarrassing if they did publish that. The main difference between the 2 is that the S652 is now claimed to be a Digital servo. Big deal. What servo today is NOT digital?If you have the spektrum S652, it appears to be better than the old ADS-15M. Mine was from 2018, so I had the ADS-15M. It lasted literally 1 turn. I replaced it with a savox 1210sg. That died after a year. Then I replaced it with a Hobbystar HCS-4521wp in April of this year. So far, it's holding up well. I put a second one in my ERBEv2. Both are running off a max6 at 7.2V. Not bad for $50. Better if you get it when it's on sale for $35-40:

RCJuice has them on sale pretty frequently.
I got one of the 25KG red ones off amazon to try if/when either of my 4521's die on me.
This S652 is a cheap servo at $13. (EBay).
Take-offs can be found everywhere cheaply. Why?
Because everyone is taking them off.
