The invention discloses a support arm assembly for multi-rotor aircrafts, a rack and an aircraft. The support arm assembly comprises a body connector, a support arm and a motor soleplate, wherein one end of the support arm is connected with a body through the body connector, the motor soleplate is fixedly arranged at the other end of the support arm, the two ends of the support arm are of a square section beam structure, the middle section of the support arm is of an airfoil-profile section beam structure, and the body connector comprises a body fixed part, a support arm fixed part and a clamp hook. The body fixed part is fixedly connected with the body, the body fixed part is provided with a hinge pin which is use for being in interference fit with the clamp hook, and the support arm fixed part is fixedly connected with the support arm, hinged with the body fixed part, and provided with a limiting piece. The support arm can effectively reduce the lift force loss caused by rotor downwash in the flight process of a multi-rotor aircraft, and improve the endurance, voyage and load capacity of the aircraft; and due to the body connector, a support arm for a multi-rotor aircraft can be simply and quickly folded, thereby effectively reducing the volume of the multi-rotor aircraft, and improving the portability of the multi-rotor aircraft.
