Industrial engine throttle control
I'm using the servo to control the throttle on an industrial diesel engine. It's mounted directly to the injection pump on the engine. I'm not sure how long it will last in this application with the heat and vibration, but I have about 10 hours runtime on it so far with no problems. The M3 ball joint rod ends that I used for the linkage have vibrated apart, but the servo is still going strong. I really like that it can be powered directly from 12V so I don't need to add another power supply or regulator. I'm using an Arduino to control it. The torque is amazing, plenty of power to pull and hold the throttle, even with the heavy return spring in place. I'm just getting ready to order another one for another engine.

Wow it is fast and strong!
Here is a before and after. The original servo was a JX 46KG coreless servo running at 5.5V from a Castle Copperhead 10 BEC. That servo is now being run at 6.5 volts and is much faster and stronger, but still doesn’t even come relatively close to this direct power. It is so strong I’ll need to be strong to do break parts on my crawler if a tire is jammed. Very impressed!!! My only complaint, two of the pins from the 4S balance port pulled out the second time I unplugged it. I don’t care since I’m going to wire a JST direct so I don’t use the balance port, but the quality is pretty hokey if you're actually going to use that.

Initial review - highly impressed
This servo is a beast!! Fastest servo I have owned and probably the strongest. Comes with a full package of goodies including stickers. Going to program the power to 95% or so. Should also mention this servo is the quietest one I've owned as well, very smooth and efficient. Will be buying another!!

Badass servo for about 30 seconds
I installed this in my 6s Kraton with a castle mmx8s ESC, connected straight to a 4s battery, set my end points on my radio then it immediately smoked my receiver and the speed controller. It did seem very powerful before it turned my whole truck into a smoke bomb though.

Why not provide the wiring 75% need
Would have given 5 stars but I had to wire up the hot leg in the 3 wire connection

One of the best for money
I’ve tried pretty much all of them. 777, nsrdc, cheap ones. These are hard to beat for the money. Power is there, noise level is low. And are quick. Would definitely recommend

Best servo for 1/8 scale rc, use it on my arrma kraton 6s exb, lots of power and speed.

This is an absolute beast of a servo, I installed this into my Hobao MTX monster truck, setting the BEC to 8.4V enabled this servo to shock me at the power and speed of this servo! I've used lower powered AGF servos in my normal 6S rigs (Mojave 6S, Bigrock 6S) and have nothing but praise for just how good these servos are. When Building up My MTX I wanted to make sure with the larger truck and tyres I wanted a much more powerful servo to deal with the extra stress bashing with a bigger heavier Truck. It has definitely not disappointed. It's a big thumbs up from me 👍👍

I bought the SA81FHXW for my 1/8 scale car but after a couple of sessions it would return to different neutral positions after steering left or right, tried resetting and changing settings - didn‘t help now if that would have been my only bad experience with AGFRC i would not have even bothered writing this review. But I also bought the A66BHLW (33kg, waterproof) for my rc buggy, so i could drive trough puddles without worries. But after only 4-5 sessions the buggy started acting weird, after further inspection i found that the „waterproof“ servo had water and dirt in it, causing it to fail. I understand that sometimes you have bad luck and mistakes in production can happen But for servos upwards of 100€ you shouldn’t have 2 different products breaking after not even 1 season can‘t recommend and won‘t buy AGFRC products again!!!
