A simple set of fairground Chair-o-planes with six seats, to be mounted by a short flight of steps, and powered by a PDU via pulleys and Meccano string.
The model can be operated by all and sundry using a press button, to delight the kids (of all ages!) as the chairs fly out with gathering speed of rotation. The model can also be driven by a Meccano steam engine, which is built into the model, though this is a bit messy for exhibition purposes.
The braced girders to qualify for the Secretary’s Challenge form the circular fascia, which is made from three 12½” yellow single-braced ones joined end to end.
The model is topped off nicely by one of Dave Taylor’s replica Meccano pennants.
