A self-styled Chinese inventor tests his homemade helicoptor. Yu Jun follows in the footsteps of his younger brother who lost his life in a national park in central China at the end of a 20 year search for the legendary Bigfoot, and intends to continue the quest from the sky. Without any formal education in aerospace science, Yu Jun spent five years constructing the helicopter from spare parts belonging to a dilapidated Lada automobile (in back).
as for the vehicles... i guess if you have no family, no loved ones, and don't care whether you get crippled or drown or whatever, then these are great ideas.
@Norm101 ...or a weird quad;)
