Why this servo? I indeed don't think you will be running it at 12v. Most bec's won't go beyond 8.4V and then it will 'only' be a 50kg servo @ 0.18 sec (still good, but you can get simular specs for 60€)

Are there any downsides for setting the BEC to 12.6V?

Your receiver will get this voltage too. Some don't even like more than 6v (which used to be the standard)

Yeah, I think he'll need to plug that servo directly into an external 3s.
 
A 70-80kg servo is total overkill in a K6. You really don't need that kinda torque (unless you plan on installing Raminator wheels/tires maybe). Can't go wrong with these guys. It's in the same price range you were looking at and these things are top notch, military grade servos and they have great customer service.

The other thing worth doing (if you haven't already) is to tighten up the servo saver. That's where you lose a lot of steering travel. There are different ways of going about doing this. Hop on Youtube and check some vids on Kraton servo saver or steering tuning. This is a very comprehensive video on how to get the most out of your steering on a K6.

This is my current problemo on my Kexb, and I have a reefs 444 in it, the servo saver is indeed the issue, it flexes open too easily and turns like a 18 wheeler under power, I just keep putting it off!! 🥸

Good to throw this in Diem, I was also thinking to challenge the original question. Sure the original servo isn't the best and you can make a 12v servo work.

But what is the real goal? What is best for @Mechanicos? A proper 30kg servo is likely just fine. For bashing you don't need speedrunning precission and too much speed and torque will probably do more damage than be 'the best'

Diem is also in Germany ;) (or at least was)

I've had good experiences with JX servo's. What would be bad about this one for example?

For Kraton EXB I would recommend either Savox 2210 or one of the AGF A81 series. Arrma 3s are a great place for cheaper servos, but you spent the extra money getting the upgraded car. Why would you put a 40 dollar servo in a 700 dollar car? Imagine getting a Porsche 911 only to put economy tires on it. You don't have to go absurdly over the top and get a Protek or high end Spektrum or Reefs, but at least put a mid range brushless servo in there.

New to the RC hobby and looking to get the perfect pass monster servo for my Felony 6s. Do I need anything with it or can I just plug and play it??
