The Arrma Big Rock is a beast of a basher, known for its aggressive handling and ability to take a beating. However, the stock steering servo often falls short when pushed to its limits. Upgrading to a more robust and powerful servo is a common modification for Big Rock owners seeking improved control and precision. This guide dives deep into selecting the perfect steering servo for your Arrma Big Rock, considering factors like torque, speed, size, and budget.
Understanding Servo Specifications: Torque, Speed, and Size
Before jumping into specific servo recommendations, understanding key specifications is crucial. These specifications directly impact the performance and feel of your Big Rock's steering.
-
Torque: Measured in ounce-inches (oz-in), torque represents the servo's rotational force. Higher torque translates to more powerful steering, crucial for overcoming resistance from rugged terrain and aggressive driving styles. A higher torque servo is generally recommended for the Big Rock's demanding operation.
-
Speed: Measured in seconds to 60 degrees, speed indicates how quickly the servo can rotate. Faster servos provide quicker and more responsive steering, beneficial for navigating tight turns and obstacles. However, excessively fast servos can sometimes lead to jerky steering if not properly tuned.
-
Size: Servos come in various sizes, dictated by their physical dimensions. Choosing a servo that fits within the Big Rock's servo bay is essential. Always double-check the dimensions before purchasing to avoid compatibility issues. Pay attention to the servo's mounting hole pattern as well.
