If you’re into RC cars, robotics, or DIY mechanics, you already know the truth: a good servo is the difference between “it kinda works” and “wow, that’s precise.” The RCmall 35KG TD-8135MG High Voltage Waterproof Digital Servo is one of those hidden gems that experienced hobbyists get excited about… and that gives beginners a huge advantage from day one. For just €16,99 (price includes VAT and there are no extra customs or admin fees, because AliExpress now handles this up front), you’re getting serious power.
What’s also great: buying through the official AliExpress listing helps you avoid overpaying. On “unknown” websites and dropshipper stores, the exact same servo is often listed for double the price, with weaker guarantees, messy returns, and typically slower shipping. So here’s the simple rule: never pay more than the AliExpress price. The price you see via this link — https://s.click.aliexpress.com/e/_c3HthxAv — is the real, transparent deal.
And that brings us to what makes this servo genuinely interesting.
Why this 35KG servo stands out
A torque rating of 35 kg·cm is impressive at this price point. This kind of servo is commonly used for:
– RC cars in 1:8 or 1:10 scale
– robotic arms and mechatronics
– pan-tilt systems
– reinforced steering setups
– DIY builds that require continuous rotation
Because it’s a 360° continuous rotation servo, it works differently from a standard positional servo. It can keep rotating in a full circle, which makes it great for small drives, wheels, or robotic platforms. Important note: with continuous rotation, angle and position cannot be precisely controlled—that’s simply how this type of servo works. Many builders actually prefer it for projects where flexibility and motion are more important than locking an exact angle.
That high torque comes from 5-stage metal gearing combined with a carbon brush motor, a setup that usually delivers durability and consistent pull. And while it weighs only 56 g, its performance feels closer to much more expensive servos.
Waterproof, durable, and built for real-world use
A big advantage: this servo is waterproof. Not just “a bit protected,” but designed for demanding conditions. In practice, that means you can drive through puddles, sand, and mud with a lot more confidence.
The temperature range is also very wide:
– Storage: -30°C to 80°C
– Operating: -25°C to 70°C
So it can handle cold winters, hot summers, and environments that are humid or dusty.
The case combines engineering plastics (PBT) and an aluminum alloy, which helps balance weight, stiffness, and heat dissipation. The 320 mm cable length gives you comfortable routing room in most RC setups.
Speed and power: the technical highlights
This servo supports 4.8V to 8.4V, making it suitable for both standard and high-voltage builds.
Speed and torque:
– 0.32 sec / 60° (4.8V)
– 0.22 sec / 60° (8.4V)
– 32.7–35.2 kg·cm stall torque
– up to 3800 mA stall current
Those are numbers you usually see in higher price tiers. That’s why it’s such a popular pick: 100+ sold and an average rating of 4.8 / 5 from 18 reviews.
Verified buyers describe it with comments like:
– “Perfect”
– “Top”
– “Compliant item and fast delivery.”
At €16,99 via https://s.click.aliexpress.com/e/_c3HthxAv, VAT included, it’s a smart buy. And there are no nasty surprises: AliExpress now calculates and collects costs up front (this used to be different), so the “customs + handling fee” stress is, for most buyers, a thing of the past.
Don’t overpay (especially to dropshippers)
This exact servo often shows up on dropshipper sites for €40–€60. You don’t get better quality, you don’t get better support, and return policies are frequently worse.
On AliExpress, returns are often free. With dropshippers, they usually aren’t. So the advice stays simple:
👉 Never pay more than the AliExpress price.
👉 Use the official link: https://s.click.aliexpress.com/e/_c3HthxAv
