I see many similar JX aluminum torque servos on Amazon with good numbers. Overall is JX a good manufacturer? Thank you again

No problem, yes JX specs are reasonably close to what they are posting and JX is the OEM for Eco Power which is touted as a very reputable brand for AMain.

Just ordered 2 servos.
AGFrc B44BLS V2 which will go into my yz10 and Power HD R12s for my RO 2.0

Anyone had any problem with the AGFrc i ordered? I know the R12s is going to be awesome from all the reviews i read.

I will never buy an AGFrc branded servo again for reasons explained here:

Simply put, AGFrc sells lower quality components which fail sooner and there are rebranded servos from NitroPro which have higher quality components where AGFrc offers no warranty and NitroPro offers the best warranty in the market. You will save more money in the long run investing in NitroPro branded servos where AGFrc is the OEM but NitroPro backs the products they sell with proper support.

NitroPro does have excellent servos.

I can imagine and I know this is possible but not always the case with OEM products. Have you proof of that claim or is it only based on some bad experiences?

Feel free to follow the link I posted which goes into detail of my experience with AGFrc to include how they slowly increased their pricing as well as absurd shipping rates for replacement gear sets and myriad of examples on 5 different types of failures that I experienced across a handful of various model numbers of servos that failed on me. I even made my own modifications to fix their shotty workmanship and compared NitroPro servos to see everything that was done differently to improve the lower quality designs coming from AGFrc branded servos.


It might be possible that AGFrc might be selling the equivalent of NitroPro servos somewhere in their lineup but I stopped taking chances on the brand because they don't offer any support leaving me high and dry.

I have had zero issues with the AGF servos I've used over the past few years. But then, I use 810BHW servos, which are rated by AGF for use in 1/8th rigs.

Top tip:

Buy from a retailer in your region.

In the UK - that's SMD direct.

So a programmer on the CT1 shows a model you could compare with an AGF. But even then the main question remains... Did AGF use different parts, did the original manufacturer use other parts to meet the price or was the CT1 a newer revision not yet available for the OEM?

I am not affiliated with NitroPro so I can't say with certainty, but my understanding is that NitroPro special ordered servos with specific upgrades to the internal components exclusively for NitroPro. I know that AGFrc offers a custom service to anyone who places a minimum order to customize servos to include any custom specs included in the order so I would imagine there are other servos out there which mirror the CT(x) specs but I don't know which brands/models have the same specs as NitroPro. All I know is that NitroPro has put a lot of effort in perfecting the poor quality designs from AGFrc branded servos.

Someone mentioned earlier in this thread that they believed the A81 series were significantly improved after I was burned on the A80 series, but NitroPro is now selling the CT3 so I have doubts that AGFrc is staying current with the latest offerings from NitroPro. It's more profitable for AGFrc to use less expensive components with no warranty support.

I realize that AGFrc claims to offer a 1 year warranty but they rejected my claim saying that I abused the servo because I used it for racing competitively on a race track. Just that alone made AGFrc dead to me.

With other words, you can not say AGF did choose the lower quality.
Also keep in mind that producing larger numbers of the same will lower the production costs. I can imagine that when a new revision is introduced the old stock is used for the OEM but at the end it is not normal to start a nieuw production based on an older revision unless some parts like chips are not available and production must go on. For sure in Corona time all electronic production companies faced issues with a shortage of chips and a huge load of fake and garbage chips which is still giving issues up on today.

The A81 was specified as suitable for 1/8th use.

The A80 was specified as suitable for 1/10th use.

The first part of the warranty states:

* Using the product in an application it was not rated for.

I have literally no idea why a servo with a 40kg of torque would not be suitable for 1/8th use - but that's what the blurb says on the site. Did they add this to the site after they failed your warranty claim?

Attempting to seek a warranty claim - internationally - without that layer of retailer protection that consumers become accustomed to, is fraught with difficulties. Principally, the manufacturer dismissed your warranty claim on point 1.

It's a lottery. I've had a Chinese seller very honourably send me parts because of a sizing issue that they became aware of. I hadn't even requested a warranty claim. So it really is like 'spin the wheel'.

In your case, it seems quite apparent that there was no intention on AGF's part of honouring your claim.

​​​​​​But if there's a lesson here - it's not that the AGF servos are 'trash' and Nitro Pro servos are 'superior'. It's that buying direct from China does not give you the same consumer rights as buying things through a retailer.

But then Chinese servos direct from China/Manufacturer cost a fraction of those purchased from retailers. It's a choice.



I realize that AGFrc claims to offer a 1 year warranty
But you repeatedly put in writing that they offer no warranty?


​​​but they rejected my claim saying that I abused the servo because I used it for racing competitively on a race track. Just that alone made AGFrc dead to me.
For the avoidance of doubt, the fact that your claim was rejected is not the same thing as stating that "AGFrc offers no warranty". It's not lost on me that the result is no replacement servo from your perspective.

I'm not speculating whether or not your warranty should have been honoured or not.

I am also confused why an AGF A80 40kg rated servo should be deemed unsuitable for a 1/8th buggy? However - it doesn't affect me - because I just wouldn't buy that servo based on that fact alone. And I haven't.

What I'll also state is that when you look at Nitro Pro servos on their presumably US website, you'd be forgiven for thinking that they have fewer servos. If they don't - their website needs to catch up with reality.

Comparing their better specced option with AGF:

FKN-500 Pro 2
$159

https://cimg8.ibsrv.net/gimg/www.rct...1f8900ca48.png
this servo does not limit its use to any particular scale. It just states: Surface.

​​​​​
AGF A81BHMW
​​​​​$108
https://cimg8.ibsrv.net/gimg/www.rct...f13820aab6.png
It's a really, really hard sell. It's seems patently obvious that the AGF's are quite different - they are much better specced!

I compare my A81's with Protek 170 SBL.

But they're half the price - and waterproof. They're also available directly from the UK at £85 ($107) - so it's a no brainer for anyone this side of the pond.

Your reviews are excellent - I enjoy your content. However, I still fail to understand your rationale on this matter. It is my belief that AGF would have been better off by offering you sponsorship, rather than deny you. But they didn't.

However, for your average Jo, in the absence of sponsorship deals, needs to understand the pitfalls of importing electronic items from China on the cheap. If/when stuff goes wrong, it likely isn't going to be economically viable to ship items overseas to check for faults on a $100 servo. If stuff fails - and you haven't bought it from a retailer - you accept that you may end up bearing the loss.

I can guarantee that AGFrc branded servos used lower quality components which I outlined in the thread, these are hard facts.

When I bought my A80 series servos they were originally marketed at 1/8 suitable servos, it wasn't until after I filed a warranty claim when AGFrc changed the specs proving they can't be trusted and will do anything to cheat their customers. I took a screen shot from the web archive to prove this:

*** VERY IMPORTANT***

What I proved is that AGFrc specs are over stated and can't be trusted, they are liars and not worth doing business with.

BUYER BEWARE with AGFrc

@billdelong what exactly is nitropro warranty? They just say lifetime manufactur warranty. Do that mean no questions asked if something breaks? Most companies say warranty doesnt cover abuse or normal wear and tear. I would consider a steering servo automatically disqualified from any warranty use.
