KST servos stress-tested - KST CM653 and X20 3012 review

[@jerryvolpini7987]

I've always found your servo tester one of the best out there and completely agree your method duplicates real world use! KST makes some great servos, thanks for putting them through their paces. Good to know their claims are not inflated. These are not your typical, cheap, Chinese servos, though. Yes, KST has a broad range of servos but their high end servos like the x20-4208 ($160) are going to cost you. Still, nice to have another great option.

Wow, thanks! Yeah, their servos are on the higher end. This CM653 was surprising since it's a performer and it's so cheap!

[@BlindGuyRc]

It's always good to have other options for servos. Great video

[@RCReviewChannel]

Agreed!

[@KickyTop]

thanks for the review. could be a reference for the selection of servo as needed.

[@RCReviewChannel]

Good call!

[@barceloni1984]

This looks like a good replacement for my utb18 capra. Lightweight with small tires, doesnt need much. But the stock one is definitely a bit too weak 👍👍

[@DustinWoloschuk]

Could you do a video explaining what all the technical terms are for servos. You did a great one with motors before explaining all the different types of motors and what eveything means Id love to see one with servos to learn what the defenses between digital and not and corless ...and kg's and stuff like that

[@RCReviewChannel]

Yeah, definitely. I'll work on it.

[@DustinWoloschuk]

@@RCReviewChannel awesome!!! I look forward to it. Your motor once was great!!!!

[@averagecarguy961]

Try a NSDRC servo for the next round of testing!

[@TheJSR111]

They have 25 dollar servos ??? 🧐

[@RCReviewChannel]

They're good. Very similar to AGF servos though.

I've had great luck with the Injora servos off Amazon. sub $40 brushless 35kg MG steering servo for my TRX4 and 7k shift & diff lock servos for $20. i run their 25k servo in my non crawler RCs.

[@RCReviewChannel]

These 35kg Amazon servos are pretty good. We've tested a few of them.

[@atourdeforce]

I think your torque testing might be flawed. Servos are rated at kg/cm that means how many kg they output at 1cm on the servo horn from the centre. Yet you set up your test at 1 inch from the centre. Thats over 2.5 times the distance they are rated at. Did you acount for this in your calculations or something? Otherwise the servos will be drastically showing under performance.

[@ryanclarke2161]

Oz per inch and kg per cm are both accepted but yes it's annoying not being in metric.

[@gregorholmes1837]

Servos are so great these days. Did you buy these or get them sent to you?

[@RCReviewChannel]

They were sent to me. A lot of servo manufacturers send me servos since they like the independence and data of the servo tester we have.

[@buysncharge]

You going to get the new MK2 VW from Tamiya?

[@RCReviewChannel]

No. Maybe that BBX Tamiya.

2nd vid ive seen where there was only one other person in comments to catch this. maybe this rig is calibrated to this length arm. Idk. Neat rig tho.
