A quadcopter is a machine that is lifted and propelled by four rotors. Unlike most conventional helicopters, a quadcopter use symmetrically pitched blades mounted on four motors to produce lift. Controlling the speed of these individual motors allows the machine to move forward and backward, up and down, strafe left and right, and rotate clockwise and counterclockwise.
Dynam has entered the quad market industry and has produced a rather unique machine dubbed the Quadcopter 550. The center frame is constructed with carbon fiber sheets and hollow carbon rods act as the support booms. This provides strength while keeping the overall weight low. The carbon fiber support booms lead to the robust cnc aluminum motor housings that house four 720KV brushless motors. The brushless motors are supported by four 18 amp Detrum brushless electronic speed controllers and allow the motors to turn the 10x4.5 rotor blades. The Quadcopter ?almost ready to fly version comes equipped out of the box with motors and speed controllers pre-installed. A flight control board is necessary to complete this quad build while Dynam pre-tins a circuit board for quick installation. An MWC board will allow fine tuning of the machines capabilities and flying characteristics while a KK board will make installation and setup easier. Either flight control boards are recommended for this type of build.
