Q. does the sound module kit have to be built from scratch, ie soldering on all resistors etc etc
A. Hi Vernon, thank you for your question. The kit is supplied as just parts, the kit will require assembly.

Easy to build nice kit .Did a mod to sound speed by making a optical sound resistor which replaced sound pot. When controlled by speed controller ,in my simulated steam boat ,gives realistic sound from stationary to full speed ahead
Easy to build

Built this unit for a ClydePuffer steamer of 1/24th scale. Modified the speed control by removing the pot and replacing with an optical pot that operates from the speed control to go faster or slower in time with the propulsion motor. Very realistic.
