Horsa glider test:  A 1/72 scale Airfix kit, the glider was run down three nylon wires, one through the centre and the other two through the wing tips.  The clip was slowed down by 50% in editing, after each take the model had to be repaired as parts fell off as it bounced off of a spring used to cushion the stop at the bottom.  The plastic kit needs to be reinforced before further shots are done, the model was 11-12 feet of the ground at it's start point, dropping to 6'6" 20 ft away.
