What the newest cheap servo hotness?

[durok]

I understood that, was just curious if it breaking prompted the breakdown and the following discovery.

My point was that I'd definitely demand my money back for false advertising!

Whether it functioned correctly or not... "thumbsup"

 

[Browneye]

From China? Good luck!
What are "fingers"?

 

[Teng]

At least they used a coreless motor

So , how about my JX 46KG servo.? From the pictures, is this servo brushless? Mine only last few minutes. ( glitching )

Teng - How was the JX 46KG powered? Direct from 3S?

It was direct powered by 4S LiHV battery. My ESC was Castle Mamba Monster X.

That'll doit. I don't know of any servos rated for 14.8 volts.

Yeah, it's listed as a 12v servo, but in the specs they do mention speed and torque figures for 14v:

- 12V High voltage
-- High performance programmable digital brushless standard servo
-- High-precision Taiwan-made steel gears with hard anodizing
-- Full CNC aluminium Shell structure
-- Dual ball bearings
SPECIFICATIONS:
Dead band: 2μs
Working frequence: 1520μs / 330hz
Motor: brushless motor
Operating Speed (11.1V): 0.12sec/60°
Operating Speed (14V): 0.10sec/60°
Stall Torque (11.1V): 38kg.cm
Stall Torque (14V): 47kg.cm
Dimensions: 40X20X37mm
Weight: 71 g
Connector Wire Length: JR 265 mm
Bearing: 2BB

I wish they made it more clear what the maximum input was, but mine is not going to get more than a fully-charged 3S LiPo worth of power.

We'll see how that works out... (eventually - ;-) )

Thank you Brother durok for enlightening me so much here. Anyway I got my full refund back. "thumbsup"

Was that bought from HobbyKing?? Looking at the HobbyKing desc, it states "Japanese brushless" and even "FSE11-4" pot but it's pot looks nothing like online pics of that FSE11.

My point was that I'd definitely demand my money back for false advertising!

I'd demand more than that, that the seller pull the whole line from the USA. FTC would love to see this considering it has "brushless" right on the case. If it was an ebay seller, you'll definitely want to contact ebay - please let us know.

It was direct powered by 4S LiHV battery. My ESC was Castle Mamba Monster X.

Jeez, now it's obvious why that died. It might have handled 3S LiHV but even a no-name half-charged 4S might have killed it. Stellar service to get your money back tho.

Yes, It was from HobbyKing, I thought it could handle direct to 14Volt and the servo aluminium case printed on it. I wonder also can this Holmes Hobbies direct handle from 4S? https://www.amainhobbies.com/holmes...-servo-high-voltage-hhbtrmblshv500sv2/p716285

This V2 servo features the use of larger gear pins to help increase durability, and can be powered directly from a 2s to 4s lipo battery, eliminating the need for an external BEC!

 

[Teng]

So, I thought mine can also powered direct from 4s, but I was wrong.:ror:

I can see how it would be an easy mistake to make, it's confusing when they labeled the JX servo as 14v.

When Holmes updated the SHV500 to v2, he did increase the amount of voltage it would take to 4S.

I have a first-generation SHV500, it is only rated for 3S direct.

 

[Hydrocarbon92]

Yes, It was from HobbyKing

I was actually asking about the Trackstar, since it looks a little diff from their Evo T3 pics. It would be a bad thing if people are intentionally selling clones, as they could likely clone more any number of servos with similar ease.

Damn. I killed my mg959v2 again today. Stripped out the big gear on the output shaft again. Some of you may remember that I had previously stripped the same gear, pulled the stop pin out of it, spun it 180°, and reassembled. I've been totally happy with its performance, but the aluminum gears are its Achille's heel. At ~$34, the 959 would still be a great value if the gears could be purchased separately, but as far as I can find, they can't be.

I had been trying to decide on my next servo, and the steel geared 46kg JX's really caught my eye, and has been at the top of my list. I don't really need any more power (did I just say that?) but I do need more durability. My only reserve is that the 12v brushless version is really creeping up on the cost of the PM470, which is kind of a known quantity, also being brushless, steel geared, aluminum cased, and "high voltage" (though 8.4v vs "12v" even though it says 14v right on the case.)

Downtime sucks, so I'd rather not pay nearly as much as a "name brand" AND have to wait a month. I can't swing $100+ right now anyway, so I'd like to hear some more real-world feedback on the cheaper jx like mikemce is running.

 

[TheLetterJ]

Ugh. I found the coreless jx7436 46kg for $53 shipped, that price and shipping from a US source makes it worth considering...

 

[TheLetterJ]

Alright, I didn't know previously that Banggood even had a US warehouse, but it said 10 in stock and 5 day shipping, so I got a JX CLS-HV7346MG coming. My buddy also ordered the JX BLS-12V7146 (Brushless with separate battery connector) from a different vendor, so it will be interesting to see how the 2 compare in the real world. We've got a local event in 2 weeks, so neither of us wanted to wait for the slow boat, so he settled for paying another $16 shipping, while I opted for the lower voltage coreless version that is allegedly shipping from the US and <$50 after coupon.

 

[mikemcE]

I almost got that, but it got BO after order. So I canceled. I think I went thru that with banggood twice before, oops not in US , computer error !


Hang up and Drive

It'll be great to hear real-world experiences with both, as I am still sitting on my hands, trying to motivate myself to build my vehicle that will be using the JX BLS-12V7146 that I have sitting on my living room table!

Was over at for 1/8 Crawler Off-road Monster #BMS-H50C, ,(BMS-H50C) by Blue Bird Full Aluminum Helical Coreless Digital Servo

Don't know if this servo has been discussed here ? Under a hundred ??
