Cheerson CX-20 - Quanum Nova Retractable Landing Gear Demonstration

A up close look at how they function in the real world. So far I've been very happy with these legs. I would say these are not for beginners but they are great for the more experienced multirotor modifier that understands how servos work . These weigh in @ about 210g. these will set you back anywhere from $40-75 us dollars
