Hi Colin, most impressed with your models and what you do with them. Having your grandson as well, that must make you feel great!
My grandaughter was with me on model boats for a few years sailing boats. Not anymore, well she is grown up and at work.
I saw you have the Bassett-lowke adverts for motors. I have a couple of them and a club member many years ago brought in one of the big ones, but he thought nothing of it and I bet it went in th skip when he died.
I have a small group of Toyshop Mamod and Wilesco accessories driven by an electric motor. Anyone seen this motor before? It is surprisingly powerful for this kind of motor.
The items to the right of the photo is a buck voltage converter which takes any voltage in and delivers, by choice 2.2 volts, to drive the motor. It all goes clankaty-bonk when running.
