Back to the Future #12


With struts pruned top and bottom we've to ask ourselves where exactly we should pitch the booms that will support each of the skis. I slid these 2400mm babies along the top of the centre-section until they pivoted near the front edge of the foremost strut... which naturally coincides with the mid-point at 1200mm (or four feet).

This provides sufficient room to swing a 22" prop at the rear, beside sufficient wood to mount the pusher-prop and motor. This is not a game-changer, as prototype 001 will merely be tested as a two-motored cat, with tuna-tin lift-motors, whilst 002 will be allocated four motors with which to demonstrate self-launch and hover.

With that done, means will be combined in order to test out the final mode of travel in the shape of flight in ground-effect, clear of whichever surface: whether snow, sand, ice, water or terrain of whichever sort.

Not going to be easy, is it Gromit?
