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 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.
