    T-440 Servo

    Posted by Mark Crowell on Dec 10th 2022

    All my items came in a very timely manner. They were also very well packaged for shipment. I bought these items for the VS4-10 I'm building just trying to get all the parts for the build together before I start. These Tekin Products appear to be top quality and I am looking forward using them in my build and in the future.

    Installed this moster torque servo on a scx10 II, and wow! Coming in at 4x the power of a stock servo its just flat out amazing. Used many Savox servos in the past but after using this servo I won't be using anything eles except the T-440!
