The Arrma Kraton 6S is a beast of a basher, capable of incredible speeds and brutal impacts. However, its stock servo often struggles to keep up, especially under heavy load or during aggressive driving. Upgrading your servo is a crucial step in maximizing performance and preventing costly damage. This guide dives deep into choosing and installing the perfect servo upgrade for your Arrma Kraton 6S.
Why Upgrade Your Kraton 6S Servo?
The stock servo in the Arrma Kraton 6S, while functional, lacks the speed, torque, and durability needed to withstand the rigors of high-speed bashing. Here's why an upgrade is essential:
- Increased Steering Responsiveness: A higher-torque servo provides snappier and more precise steering, crucial for navigating tight corners at speed and maintaining control during jumps.
- Improved Durability: Stock servos are prone to stripping gears or failing under heavy stress. A robust upgrade significantly extends the lifespan of your steering system.
- Enhanced Performance: A faster, more powerful servo translates directly into improved handling and control, especially at high speeds or when tackling challenging terrain.
- Prevention of Damage: A weak servo can lead to stripped gears, broken linkages, or even damage to the chassis during impacts. A stronger servo helps prevent these costly repairs.
Choosing the Right Servo: Key Specifications to Consider
Selecting the perfect servo for your Kraton 6S involves understanding several key specifications:
1. Torque:
Torque is the twisting force a servo can exert. For the Kraton 6S, you'll want a servo with high torque, typically in the range of 200 oz-in or higher. This ensures the servo can easily handle the demands of the powerful 6S power system.
2. Speed:
Servo speed is measured in seconds to move 60 degrees. While high torque is crucial, you'll also want a relatively fast servo for responsive steering. Aim for a servo with a speed of around 0.10 seconds/60° or faster. However, prioritize torque over speed; a slower, higher-torque servo is better than a fast, weak one.
3. Size and Mounting:
Ensure the servo you choose is compatible with the Kraton 6S's servo mount. Most aftermarket servos will fit, but double-check dimensions before purchasing.
4. Waterproofing:
The Kraton 6S is designed for aggressive bashing, often in less-than-ideal conditions. A waterproof or water-resistant servo is highly recommended to protect it from mud, water, and dust.
5. Brand Reputation:
Choose a servo from a reputable brand known for quality and reliability. Brands like Savöx, Futaba, and Hitec are popular choices among Arrma enthusiasts.
Popular Servo Upgrades for the Arrma Kraton 6S
Several servos consistently receive high praise from Arrma Kraton 6S owners. (Remember to always check compatibility before purchasing):
- Savöx: Savöx servos are known for their high torque and durability, making them a popular choice for high-power vehicles like the Kraton 6S. Look for models with high torque ratings and waterproofing.
- Futaba: Futaba servos offer excellent precision and speed, but often come with a higher price tag. They are a great choice for those prioritizing top-tier performance.
- Hitec: Hitec offers a wide range of servos suitable for the Kraton 6S, catering to various budgets and performance requirements.
Installation: A Step-by-Step Guide
The installation process varies slightly depending on the specific servo, but the general steps remain the same:
- Disconnect the battery: Always disconnect the battery before working on any electronic components.
- Remove the old servo: Unscrew the old servo from the servo mount.
- Install the new servo: Carefully mount the new servo onto the servo mount, ensuring it's securely fastened.
- Connect the servo leads: Connect the new servo's leads to the receiver following the correct wiring diagram.
- Reconnect the battery: Reconnect the battery and test the steering functionality. Adjust the servo's endpoints in your radio's settings if necessary.
Conclusion: Elevate Your Bashing Experience
Upgrading your Arrma Kraton 6S servo is a relatively simple yet highly effective modification that significantly enhances performance, durability, and overall driving experience. By carefully choosing a high-torque, waterproof servo from a reputable brand, and following the installation instructions, you can transform your Kraton 6S into an even more powerful and controllable basher. Remember to always consult your vehicle's manual and the servo's instructions for specific guidance.
