The top servo we got for you is the ZOSKAY High Torque Coreless Motor Servo. According to our calculations, this is the best servo for Arrma Kraton. In a bit, we’ll explain why this servo seems the best deal.
First of all, this ZOSKAY servo’s gear is made of stainless steel. This means the gear will not get rusted too easily. On top of that, it’s also waterproof which ensures underwater RC submarine ride.
It provides a control angle of 270°. So, it’s ideal for RC cars and robotic parts.
And it’s actually very easy to install. In fact, you’ll need only 10 minutes to set things straight. You won’t feel it as a hassle at all.
But the best part of this servo is that it works really well as a digital servo. The torque rating of 35kg/cm @7.4V is a reason behind its mind-blowing performance. Besides, this high torque rating ensures both precision and accuracy in action.
You can use it with the Sanwa MT-S radio and RX-482 receiver. Power it up till 7.4V at 10 amp, you’ll get to reach the strongest peak!
And as it uses a Coreless motor, you’ll get higher speed and performance.
However, there’s only a small drawback to this servo. Though you get the main gear made of stainless steel, the extras are made of plastic.
You won’t get the same performance from the plastic gears as the stainless steel one. So, this is slightly a concerning issue.
But overall, we think it’s absolutely amazing for the price it comes in.
- Has full metal gears which means it’s suitable for high-impact application.
- High torque ensures full control over your RC vehicle.
- Has larger dimensions which is good for bigger RCs.
- Has an Aluminum case that makes heat dissipation easier.
- Doesn’t rotate more than 160-degrees.
- Heavier than other servos.
So, the next servo we have is the Digital Servo Full Metal Gear High Torque Servo.
It has metal gears which means this servo is a beast for high-impact applications. Also, it’s pretty strong and responsive. So, you don’t have to worry about steering response anymore.
Speaking of its torque speed, it’s quite good enough to help you control your RC. But the torque speed is almost half that of the ZOSKAY’s servo.
It has a controllable angle ranging 0 degrees to 180 degrees. In some cases, you can rotate it to 360 degrees too! If you’re a robot enthusiast, it’ll help you tremendously.
What we really love about this servo is that it fits well in bigger RC vehicles. And the Aluminum case helps to keep the motor functioning even at maximum heat.
But as the case is made of aluminum, it is slightly heavier than other servos.
Not to mention, the price is extremely budget-friendly. It’s about 2x lower in price than the other servos we reviewed in this article.
- Built with Iron Core Motor that ensures more power capacity.
- Works great for developing robot parts with software.
- The motor doesn’t get too hot even using a 2000 mA hour 7.2 V battery.
- It’s so powerful that it beats the two-steering servos in turning tires.
- Doesn’t fit well with heavy-weight rims and tires.
Next, we’re rooting for the coolest servo for Arrma Kraton. It’s the BETU 2Pack 25KG High Torque RC Servo. It boosts the acceleration power of your RC.
Now, why are we calling it the COOLEST? The reason lies with the motor it uses. Even if you run it for 2000 mA per hour, it doesn’t make your RC hot. This is why we love this servo so much.
It’s almost the size of the ZOSKAY servo we reviewed above. However, the gear material matches with the Digital Servo ones.
Well, there’s a unique feature in this BETU servo. Apart from using it in Arrma Kraton, you can use it in developing robot parts.
This servo is compatible with different sized RC cars. For example, it goes very well with 1/6，1/8, 1/10, 1/12 RC Cars.
But there is a small drawback to this unique servo. It is not very compatible with heavy-weight tires and rims. The lightweight material and small size is responsible for this.
However, we think this servo does the best job having a price tag below $40.
- It has a brushless motor for which it responds pretty fast.
- Compatible with 2S LiPo battery without BEC because it can operate on more than 7.4 V.
- Flicks tires left and right excellently.
- Functions well even after staying underwater for 2 minutes.
- Short wire harness.
- It might need a slight trimming if the frame is rubbed a bit.
Introducing our next star – the Powerhobby 729MBL High Voltage Brushless Steel Gear. When it comes to performance, it’s a beast having the highest torque rating on today’s list (40kg/cm @ 8.4v)
It has a built-in brushless motor which gives the servo supremacy in responses. You can notice how your RC tires steer when you use this bad boy.
If you’re looking for a dashing waterproof servo, Powerhobby should be on your list. Take your RC underwater. Spend almost 2 minutes and still it’ll work as a brand new model.
But one thing might piss you off a bit. The cable you’ll get is a little shorter than the regular ones. If Power Hobby would have extended it for only half an inch, it would’ve been perfect.
It’s a waterproof servo which is compatible with 1/10, 1/8 on road, off road, truck/cars.
Other than that, it has an outstanding gear quality. And you’ll definitely be impressed by the torque it produces.
Hence, it is more expensive than the other servos we reviewed in this article.
- It uses a brushless motor. So, you get quicker torque through the servo.
