What do 3 gimbals do that 1 will not? Do more gimbals give you a more steady picture? I am thinking about a Phantom 3 but only the standard edition. I guess it has fewer gimbals. I would like to stay under $500 and get the most steady picture I can.
I guess you are referring to 2 Axis vs, 3 axis gimbals. A Lot of nice work can be be done with the less expensive 2 axis types. This guy is using a 2 axis $60 gimbal. Some good tips for your future endeavors.
