I built this from a kit. This is NOT A TOY. You must know how to fly. There is no GPS help. It has a onboard programable flight controller. It flies well when all set up. Flight controller can be used on helicopters and fixed wings as well for stabile flight. Comes with a crash kit. It is a class 300 with 8" props. Uses 3 cell 1300-1800 MHA batteries. I travel often to Victoria and can deliver.
