Standard Decoders

Standard decoders mean that you can control motor and one or more auxilliary/function outputs (for lighting, smoke etc.). These are NOT sound decoders. Choose based on size, motor power output, and required outputs.

Zimo standard decoders are probably the best available for fine motor control and offer a variety of CVs to assist in tuning outputs to get the best from your models.

Ask if you need help choosing! YouChoos holds stock of most of these decoders.
