DS3225 25KG Coreless Digital RC Servo, Stainless Steel & Aluminum Metal Gear – High Speed High Efficiency High Torque Waterproof Servo for Baja Cars RC Robot (Coreless Angel 270 Degree)

I put this in my Arrma Granite and have beat the heck out of it. I've had the servo saver brake but the servo has never failed. It has good speed and plenty of torque. I will be buying more for my crawlers.

I haven't yet put this servo through its paces completely, but I tested it against 4 other servos with somewhat similar specs (all 20 - 25Kg) back to back in a few basic tests, and so far, this totally blows the competition out of the water. Very responsive, speedy, smooth, strong, and surprisingly, the current draw I was getting at 7.4V (which is the maximum recommended to supply to this servo) maxed out around 0.77A with no load, sweeping very quickly. The other servos were in excess of 1.15A, despite having less torque and slower speeds. It was also the only one of the bunch that could exceed 180 degrees (capping out at the indicated 270). Can't wait to start adding these into some robotic parts, will update this review as I continue.

I have twin Savox 1258tg servos on my Revo 2.0, they are noisy, and get hot quick even though I have set them perfectly. This servo I put in my Arrma Outcast 6S, and wow what a difference. Dead quiet, is strong enough to flex off your stock servo mount, so make sure to pay attention to your endpoints. The clamping horn is cheap junk, the set screws are weak, and if you plan on using it (I do use it) you'll need a few things. First, a shorter screw, first time I powered it up the screw stuck thru the bottom and ripped the label off. Second, you'll need a longer screw for the steering rack horn & a few bushings, and additional washers to raise the linkage to level. Don't try to not level it. It will throw off your setup, and not center right. I'm running off the stock esc with a ProTek glitch buster in my futaba reciever, soon I'll add a BEC and crank it to it's full potential at 7.2v instead of 6.0. The "weakness" the other person felt was probably due to a loose servo saver, once tightened this thing is strong, and unbeatable for the money.

Servo is extremely quiet and very precise and fast. However it doesn't fit my B44.3 because the geometry is different than the Savox it is replacing. The top part is taller and doesn't slant down causing the bell crank to hit it in the standard mounting location.

When I first got this servo it just felt sluggish, weak and didn't want to center compared to my Savox 1211SG in my Arrma Outcast, found out my servo saver was binding up fixed that and now it works great, faster and stronger than the 1211SG was. I might have to buy a couple of these for my Summit to replace the cheapo eBay servos that are in it now.

I do not submerge my crawlers in water so can't comment on that. This servo is unbelievably quiet, pretty fast, and very strong on 6.0 volts. So far so good but I would buy this for any crawler/trail truck out there needing 20-30kg of power.

Mine broke the second battery I ran through it.

I used this on my axial wraith spawn and it has so much more power than I expected. It's a good servo for the price
