Another alternate build for the Getaway Racer. This time a Centrifuge. The model demonstrates Centrifugal force beautifully, as the "beakers" swing outward during spin. My wife is a chemist and forced me to go through a number of major redesigns to achieve the look of a bowl in which the beakers spin. The LXF contains a group that simulates part 12799 (the engine). Apologies for that, but LDD does not support that part. Enjoy. Comments and suggestions welcome.
