Thanks for spending all that money and running the test. I'm sure a lot of us benefited from knowing which brands are true to their claims.

[@LawrenceTimme]

You do all these servo test but it's hard to remember which does which to compare, it would be great if you could do a round up at the end, and put them all in a bar graph with overall torque, sorted by power volt X amps, and also them sort for Oz per $ 👍

[@tonysweet9137]

I agree this information is useless. I give up on trying to remember all this. What a shame too.

[@RCiler]

@@tonysweet9137 Why is it useless.. If you decide on a servo... a few clicks on the progress bar gives you the information about it. I'm just not sure why would anybody need a 47kg servo in a crawler.. other to use it as a boulder wedge in a quarry...That will break most crawler parts...

I have found a very cheap, powerful, and fast brushless servo for 23 dollars!!!!!!!!!😮 Gx 42kg brushless servo on ebay. It is unbelievable for the price. It blew my mind... I've ran it at a race this past weekend, and it ran flawless. Very strong, and centered very well. Hope you reveiw it one day! Great video!

[@frumpadumpf5173]

Very informative and useful! really opened my eyes to how much current these high torque servos actually pull. I've always assumed 3 or 4A were the maximum at full torque, but seeing 7A...Wow! Makes it easier to choose a BEC as well.

My 1st RTR when I got back into RC was a Redcat Gen 8 Axe, and ever since Reefs has been my go to for servos, and Hobbywing for ESC and Motors. I have to Admit I have been thinking about building a purely Holmes Hobby crawler just so I can compare the two top dogs, at least from the word on the grapevine. Maybe on the SCX10iii chassis. I will add a Thank You, if I haven't already because your review was the tipping point on my 1st RTR and I still think my Axe is the best RC I Own, I did ungrade to an AXE FOC R2 540L 2800KV, for the wheel speed, extra punch, and for the dual mode to also use as a trailing truck.

[@gheorgheoltean4467]

Thanks for sharing and ... One of the best Chanel!!!

[@happyhappyjoyjoy6563]

good stuff, thanks for that i like your set up professionally done cheers

[@RTmadnesstoo]

Have you seen the Boom Racing Python servo made to be axle mounted? It doesn't have tabs on the ends but has one rail down the side to mount directly to the truss or an adapter bracket. It looks very streamlined and waterproof with a 45kg rating. I guess you would have a problem trying to use your rig to test it but I sure would like to see how it compares. You guys are doing an excellent job and I thank you for spending the time and presenting it for us. Have you thought about how to check the calibration of your rig? It wouldn't be hard to put a pulley up at the top and a pulley at the edge of the table to hang calibration weights.

[@bongofury3176]

Been using Bluebird brushless titanium alloy geared servos for my 1/10th and 1/8 crawlers and they have never failed me. I suspect they will last forever. Also have some Savox which are equallly good but more expensive...

[@mdkenley1]

I was a fan of JR back 20 years when I was racing qscale. Are they still around and good quality?

[@hemitj]

What about all the noise from them? What was the quietest?

[@hillie47]

With a bunch of them you see a downward trend due to heating up. It would be interesting to see how servos hold up with repeated pulls over an interval and where they stabilize. Something like 20 or 30 pulls, 10, 15, 20, 30 or 60 seconds apart and see how their performance changes over time.

[@Lagndon84]

How come the Holmes 550v3 is tested at 10V?

[@vincevirina425]

thank u for the information

[@tekinprez]

You need to factor in the current draw. Some are drawing 8 or 9 amps to make that torque which they may not have when connected in RC system. Some also get hot and then perform a lot differently. In many applications it is about repeatability and accuracy more than max torque.

[@johncomito4853]

What steering servo should you use on the Xmaxx RC truck my 2085X keeps blowing out every other time I use it should I use the savox 2290

[@chinovillanueva8630]

What an awesome test! I actually saw this video a year ago, but re-watched it because I am looking for a new servo now. I noticed the hitec servo really had low amp draw, is it because of the regeneration feature? Also, does this hitec servo with regeneration (current back flow) feature cause problems with electronics like the castle esc’s or othe esc?

[@keithcerce8445]

Thank you, thank you.

[@jeanpmagnanig]

I recently bought the Reef Triple5 and I love it, I actually think is it waaaaay too much xD

[@tomlucasrccrawlers9108]

Then the 444 might be your cup-of-tea. The 555 is the same servo with steeper gears for more torque but slightly less speed. The 500-Raw is way faster than the 444 with just a hair more torque than the 555.

[@JoeOvercoat]

A three figure $ervo!

[@one10RC]

I have the Triple 4 and the Triple 5; the 5 is definitely a little slower than the 4, but has mammoth power!

Hi; Thanks for sharing all the info and clearing up some of the claims out there. I looked at the SAVOX SB2230SG site and they run it at 7.4v. You did it at 8.4v @ 41.6kgs if I am correct. Can you check it at 7.4v as they claim to have a torque of around 580 oz and give me an answer if it still stands up to the test.

[@jeffreylo8608]

Great video! What happened to that Element body your left :)

[@RcOffroad9513]

I seen you had a JX Hv servo in the line of servos to be tested in the video, but never tested it? I have 3 Jx Bls7132 HV servos they are supposed 5o have 32kg at 7.4. If you have this servo, can you test it and tell me the results? Thanks great video!

Is the Hitec at 2:40 really only drawing 1.8 amps at max torque? That's a few times more efficient than the other ones. How do they do it?

[@jamisjamison6990]

I like the G13. From 3 Brothers RC running straight from a 3s battery.

[@LyroLife]

The tekin did not make any noise. Is the sound muted or is it really that quiet?

[@saltylocal6917]

Any recommendations for a quality servo that is fully compatible with a stock Kraton 6s RTR?

[@kyhonjan]

We can assume the comparison of outputs between tested servos but the values we should take at face value. Also note that if one wishes to invest in a stronger servo one should also consider the investment of replacing plastic steering components with metal ones as the strength of some servos quickly flog steering components to consistancy of soft ice cream.

[@jadeddragon4254]

I found a redcat gen 8 that was half submerged in the mud in a stream. It had obviously been swept downstream and it was there for awhile because it was oxidized to hell. Everything was completely waterlogged.The Savox servo still works and as a matter of fact I still use it in that same redcat after rebuilding it. Testament to quality ?

[@RC_Rooster]

Gotta see an update on this one. Is the rig still around?

[@douglaselliott8298]

I got a Savox 1231SG in my TRX-4. The traditional Savox hum is mostly benumbed by the stereo headphones I usually wear. I don't know if it achieves its claimed 444oz at 6.0V but it rarely suffers a 'stall' while crawling my 7+lb truck. It's NOT rated waterproof, but at $69.99 on Amazon, I don't much care being I live in the Ca. high desert. I may buy one for my RR10 Bomber if the OEM servo ever fails.

[@catherineharris4746]

[@DavidRamirez-eo1nf]

I have to say, the results of these tests have surprised me and left a bittersweet taste in my mouth. On one hand the servos I loved the most have turned out to not have the torque claimed BUT on the flip side, it's encouraging because I realize I'm not crazy for wanting more than "650 oz in" of torque. What I'm saying is, this whole time what I thought was over 600 and 700 oz/in was actually only 300ish and there are legit servos out there that I have yet to try. Thanks a lot! Now I know who has the real deal! Reefs triple 5 and Holmes v3 are what I'll be buying from now on. Only 20 bux more than I spend now anyway 🤷‍♂️

[@mossyhollow3732]

Do the manufacturers measure with an arm or centered on the shaft?

[@RCReviewChannel]

They official spec is oz/in is 1 inch away from center. For kg/cm, it's 1 cm away from center.

It was tested at 16.8 volts. It's crazy strong but it gets hot and it's flexing our test machine. We have . avideo too of it pulling at 14 volts and that and 11 volts are better for it. Very strong and stable kzbin.info/www/bejne/qqPKoZhjl51nhq8
