The all new and improved Sidewinder 4 builds upon Castle's most popular platform - the Sidewinder 3.
The Sidewinder 4 is the first platform running Cryo-Drive technology which reduces operating temperatures in all applications. Cryo-Drive is a potent combination of software enhancements and precision fluid dynamics. The new case is designed specifically for maximum airflow from the huge 30mm fan included with the Sidewinder 4. These changes result in cooler ESC temperatures, increased runtime and power handling. All of these improvements mean you can gear more aggressively for more speed and harder/longer runs.
Of course it is still waterproof* and compatible with the optional Castle Link USB programmer.
The Sidewinder 4 is a versatile ESC that can be used in a wide variety of applications. It is available by itself or paired with a Castle Creations 4-pole brushless motor. It can also be used in a rock crawling applications with a brushed** motor down to a 19 turn.
Not intended for operation while submerged in liquid. If unit is operated in wet conditions, rinse with fresh water to remove dirt or corrosives, then fully dry unit.
**Brushed motors are recommended for rock crawlers (vehicles traveling 3-5mph.) Brushless motors are fine for use with rock racing. If your vehicle is going to be in a bound up situation, very slowly traversing rocks and obstacles, you are running a rock crawler. If you are constantly travelling at 5mph or higher, you have a rock racer.
We want to ensure a smooth delivery experience for you, and here are some key details to keep in mind about our service.
- For orders exceeding £120, delivery is available exclusively to mainland UK addresses. However, orders below £120 can be delivered to outlying Isles and Northern Ireland, provided they meet specific criteria: they must be deliverable by Royal Mail, weigh less than 30kg, and fit within the dimensions of 61cm x 46cm x 46cm. Please be aware that certain highland areas may entail additional delivery fees, as couriers often charge more for these deliveries. If you reside in the highlands or any outlying regions, we recommend reaching out to us before placing your order to verify delivery options and any potential extra charges.
- Delivery is typically included in the price for the majority of our products, unless otherwise specified. However, please note that orders under £80 will incur an additional delivery charge. You can easily view this charge on the checkout page when finalising your purchase. We aim to maintain transparency in our pricing structure while providing you with the best possible service.
- Most orders will be delivered via either a next working day delivery service or within 2 working days, depending on your chosen service. Please note that for next working day delivery, the cut-off time is 12pm, and dispatch occurs exclusively on weekdays. However, certain items may have longer shipping times, and the expected delivery period will be clearly specified in the product listing.
- To streamline your order fulfillment process, please note that when your order includes items with varying shipping times, we follow this approach: If any item in your order has a longer shipping time, we will hold the entire order until all items are in stock. However, if certain items are expected to be restocked after a considerable delay, we offer you two options. You can choose to wait for complete fulfillment, where we'll dispatch the order once all items are back in stock. Alternatively, you have the option to receive a partial delivery, where we'll promptly send you the in-stock items and deliver the remaining items as they become available. Your satisfaction and convenience are paramount, and we strive to accommodate your preferences for multi-item orders.
- To ensure efficient delivery, we work with trusted carriers: DPD Local for next working day delivery and Royal Mail for the 2 working days option.
- After dispatching your goods, we'll promptly send you an email containing the parcel's tracking number. To ensure you stay updated conveniently, kindly provide a valid mobile number, which we will add to the consignment. This way, you can receive real-time updates on your mobile phone for added convenience.
- For listings specifying a shipping time of "Dispatched within 3 working days," please note that orders under this category will typically be delivered within a timeframe of 3 to 5 working days.
