If you do not plan on driving your rc in wet conditions then no there is no reason to get the waterproof one.

maybe not right now until i get bored. i do have a dust cover so should protect it from rain or snow. i know i wont be jumping on muddy puddles for sure.

Okay all.... I've been looking at this for days. Simply looking at paper stats, not knowing anything else about these, here are some top options I've found in no particular order. My selection criteria were:

Well most servos are rather easy to waterproof, you just need some modified silicone conformal coating and marine grease. You can also use liquid tape and marine grease but you have to put the liquid tape all over the seams on the outside of the servo and it just looks hideous.

There are tons of videos on YouTube that show you how to do it.

I use the Power Hobby 729 MBL. I have 5 of these in my 6s rigs. Excellent servos. Been running them for years with zero issues. 500oz on 7.4 is more than enough for a Kraton. They’re fast, powerful, and for 95 bucks, it’s a no brainer. Easy to find on Amazon, amongst other websites. Same specs as the Savox 1212, except standard height. (1212’s are are little taller, and make noise, and personally I think the 1212 is a little slower than the 729). You don’t need an external battery or BEC. No glitching or anything extra. Plug into your receiver and go. One and done🤙🏻

I considered one of those, went back and forth between that and a Bluebird BLS-4311 for a few days. Ended up with the Bluebird but I think it has too much torque for my Kraton :ROFLMAO: way better than any Savox I've had.
I want to try one of these next https://www.bluebirdservousa.com/product-page/bls-m52b-magnetic-sensor-helical-gear-servo

That’s some mean specs right there! Never heard of them. Definitely gonna try one on the next build. I like that they use hall sensors. Next gen tech right there. We use them in helicopter gimbals.

I disassemble all my new servos out the package, no matter the brand. I have gotten defective ones. DOA. They get returned ASAP. I Evaluate them, test them on my Servo testor and apply Conformal coating to the PCB's, spread grease around all the gears lightly. Usually you find one small blob of grease that sits on one gear and never touches the Teeth of any of the gears. And some have Zero grease (Dry) And I found some Servos with no Conformal coating at all, despite claiming to be WP.
I don't expect most to do this. But food for thought if you are so inclined.
Just that I have good luck with servos now, and most of them are AMZ cheapos.
:cool:

Like I've said a few times I love the red ones I still have some that are 3-4 years old now but for some reason the blue ones hate me every one of them that I have bought has turned out to be a dud.

@slick2500 was the questions not best servo money can buy implying that money is not a question in what were picking there for picking an amazon cheapo is the problem in this thread no?
Some people can't possibly consider anything else but budget and value for your dollar.

In racing, like in life, we call these people losers because they will never compete with the best. Only fight over the discounted left overs. The scraps if you will.

If you want the best, you have to pay like the rest.

Sorry if I hurt your feelings 🥺

The problems not his opinion. Its that he has a post after every other opinion on here discrediting the other opinion. This is not a debate. Quoting my self "IMO" in my opinion.

Its ok to have and opinion its not ok to police others.
