With the few props left from the presentation I make a mock-up for my own benefit and it's a testament to the methodology that it's so simple. Specially pleased with the blades, cut from fascia-board that would otherwise be wasted on a conservatory. As helicopters go it looks a lot of fun (of the kind which seems to have got lost along the way). If the weight is kept in check it's a safer place for the propellers, and may yet be the one I choose to prototype at full-size.
