I have been using a red ribbon hanging from the lower left skid to determine orientation when the Phantom is far away. Today I was descending rapidly & the ribbon was pulled up into a prop & wrapped around the motor. The quad flipped upside down & fell 30 feet before crashing. Fortunately it landed on 3 foot long grass so no damage was done. So if you use this ribbon idea make sure the ribbon only hangs down 5" so that it can't reach the props.
