Hi Mike. The model has a lot of quality to it and the Walsall wheels let it down quite badly. It looks resplendent with the new Slater's wheels, and will now run on FS layouts. It just seemed sensible to update the motor too so it would run better with modern electronic controllers. Thought it would be sensible to sell the redundant motor and wheels to subsidise the upgrade. Better to pass the motor on to someone who may find a use for it.
