In developing the knowledge and information about the Quadcopter aircraft, the parameters related to aircraft lift capability factors; fly long; flying high; type of motor; the type of propeller; including the sensors and control systems used. To find out of the BLDC motor voltage source to the rotor angle velocity (ω) relationship; rotor speed to wind velocity through rotor (v); rotor speed to rotor lift (Ft); wind speed to rotor lift; push the following rotor (Ct).Test and measurement results data show that; the lift force generated with rotational speed relationship is not proportional Nonlinearity occurs when the rotor is released from the self and starts pulling the strain gauge when the rotation speed reaches around 65 rps. Once the rotation speed of the rotor is able to reach up to 1.5 Newton lift then the thrust rising trend increasing sharply to the increasing the speed of rotation of the rotor. A special rotor that has BLDC motor specifications such as; 1200 KV, 12 Volt and 30 Ampere; blade with a radius of r 0.12 m; at a temperature of about 27 oC; in the condition there are no other wind currents then obtained thrust (Ct) of 1.732.
