Sorry for the perhaps confusing title.
This is an electric motor setup for a RC boat or launch that is very cleverly and realistically
pretending to be a live steam plant with boiler and vertical twin for a boat like a Windermere launch
It looks really good and the twin oscillating engine is made of brass and so definitely has the
feel of a real steam engine. It is in fact just turned over by the electric motor.
There is also an additional motor with prop shaft and prop that you might find useful.
I have tested both motors and they both work.
There is no battery (you can see the tray for the battery to sit under the boiler cowling) and no RC gear.
I don't know if the sliding variable speed resistor for controlling the motor speed works as You probably need
the resistance of the prop in the water to judge.
Base plate is metal, sturdy and is 33.5cm long and 148mm wide at the widest and 85mm at the narrow other end.
Total height is approx 24cm tall including the chimney.
Boiler part is approx 3.75" diameter by 4.5" long with the black part (with the chimney situated) being a further 3.25" long.
Coke can to show an approx size/scale, and is not included in the sale !!
I can post or you are welcome to collect from Corsham area of Wiltshire.
