Hi, I have a large live steam tug with a stuart turner 4000 boiler and a twin engine with reverse etc plus all the gear. however as it is to large and heavy for me to handle at 83 I am hoping to convert it to electric motor with speed controller. it has all the servos fitted and a remote control, but would like some advice on how to fit it out with electric conversion,[ engine size etc ] 😊 the steam plant will soon be for sale
