Description
Overview
SRT High-Voltage Coreless Digital Servo, 277.7 oz-in, 0.09 sec @ 8.4V is a performance-focused SRT servo for builders who want sharper steering response, dependable holding power, and clean control feel in demanding RC applications. It is suited for 1/10 to 1/8 scale RC cars and trucks and works well where the torque and speed profile matches the vehicle.
Use this servo when upgrading from a stock RTR unit or refreshing a competition build with a more precise digital steering solution. The SRT design emphasizes fast response, strong centering, and durable gearing so your RC vehicle tracks consistently through corners, impacts, and repeated high-load steering inputs.
Key Features
- SRT digital servo built for 1/10 to 1/8 scale RC cars and trucks
- High-Voltage electronics with durable metal-geared construction
- Optimized for steering performance, throttle/brake control, or auxiliary duty depending on the vehicle setup
- Direct replacement/upgrade option for drivers wanting stronger response than a basic RTR servo
Performance Benefits
- 277.7 oz-in torque for confident steering authority under load
- 0.09-second transit speed for quick steering response
- 8.4V operation to match modern receiver and BEC setups
- coreless digital control for precise centering and repeatable feel
Usage Notes
Best used with 1/10 to 1/8 scale RC cars and trucks. Verify servo size, spline compatibility, receiver/BEC voltage, endpoint setup, and steering-linkage clearance before installation. For high-torque servos, set endpoints carefully and use an external BEC when the vehicle electronics require additional current capacity.
