What makes the SW-2290SG ideal for high-performance builds?

The Savox SAV-SW2290SG Monster series servo with CNC aluminum case, steel gears, and 25T spline output is designed for builders who demand maximum torque and reliability. Its brushless motor and digital HV controller deliver 35% more power than previous generations, while the direct-drive architecture and VR potentiometer ensure precise positioning under load. Whether you're steering a large-scale crawler or controlling robotic arms, this servo offers the strength and responsiveness needed for mission-critical tasks.

How does it perform under voltage variation?

The High-voltage brushless servo with 70Kg peak torque @ 8.4V, 0.11s response, and 9200mA blocking current operates across a wide 6.0–8.4V range, making it compatible with 2S to 4S LiPo setups. Its rated current draw of 220mA and quiescent current of just 5mA ensure efficient operation, while the 9200mA blocking current capacity protects against overload during extreme maneuvers.

Is it suitable for outdoor and wet conditions?

Absolutely. The Waterproof IP67 servo with steel geartrain, direct-drive architecture, and CNC-machined aluminum housing is built to withstand mud, water, and dust without compromising performance. Its sealed casing and robust internals make it ideal for off-road RC vehicles, marine robotics, and any application where exposure to the elements is a concern.

What applications benefit most from the SAV-SW2290SG?

The Savox SW-2290SG servo with 3 ball bearings, 5mA quiescent current, and 220mA rated draw for efficient operation is perfect for 1/5-scale RC trucks, rock crawlers, robotic platforms, and heavy-duty steering systems. Its 25T spline ensures compatibility with standard servo horns, while its compact 41mm x 21mm x 39.9mm dimensions allow for easy integration into tight builds.

We want to make sure your delivery goes smoothly, so here are some important details about our service:

• For orders above £120, we offer delivery to most mainland UK addresses. For orders under £120, we can still deliver to Northern Ireland and the outlying isles, as long as the item can be sent by Royal Mail, weighs less than 30kg, and fits within 61cm × 46cm × 46cm. Some highland and remote areas may carry an extra delivery charge as couriers often apply surcharges in these locations. If you live in one of these areas, feel free to contact us before ordering so we can confirm the delivery options and costs for you.
• Most of our products include delivery in the price. If your order is under £90, a small delivery fee will apply but do not worry this will always be clearly shown at checkout before you complete your purchase.
• Depending on what you choose at checkout, your order will usually be delivered either the next working day or within 2 working days. For next day delivery please place your order before 2:00pm. Orders are dispatched Monday to Friday only. Some items may take a little longer and if that is the case we will always show the expected delivery time on the product page.
• If your order includes items with different dispatch times we will normally wait and send everything together once all items are in stock. If one of the items is going to take a while we will give you the choice either wait for everything to arrive or let us send the available items now and deliver the rest later. It is up to you.
• We use trusted delivery partners to make sure your order gets to you safely and on time. We use DPD for next working day deliveries and Royal Mail for the 2 day option.
• As soon as your order is on its way we will send you a tracking number by email. If you provide your mobile number at checkout we will also send delivery updates straight to your phone so you can keep an eye on progress.
• If a product is marked as "Dispatched within 3 working days" delivery usually takes around 3 to 5 working days from when your order is placed.
• For customers in Inverness and other parts of the Scottish Highlands deliveries can take up to 2 working days even if you select next day delivery as couriers do not currently offer a guaranteed next day service to those areas.
