Self-Trimming Flown Units

Michael Patterson

Bringing flown units to a gentle stop as they touch down on a stage floor is usually a simple task. But the results of a botched “in” are as ugly as they are familiar. Stop short of the floor, and the units hang in mid air, twisting or swinging back and forth in response to the slightest movement nearby. Overshoot the low-trim spike, and they bang into the floor and then lean crazily out of plumb. Normally, rig trimming and operator training will eliminate most such possibilities. But when they don’t, the best solution may be to give each unit a self-masking and trim-correcting foot like those developed by University of Virginia Technical Director Jeff Dennstaedt.
