SkyBeans ChaseCam allows paraglider or paramotor pilots to set their GoPro up to fly behind them, taking steady film or stills.
It weighs just 170g and consists of a plastic case that fits a GoPro Hero 3, 3+, 4 or GoPro Session, a length of thin, stretchy bungee line, and what looks like a giant badminton shuttlecock (the wings). The wings keep the camera steady in the air. They are made from bendy plastic which can survive being bounced about on the hill without breaking.
