7045(7X4.5) SF Propellers are high-quality propellers designed explicitly for multi-copters. These Props are lightweight and high strength providing an angle of 15° design at the end of the propeller. This 15degree avoids whirlpool multi-copter flying. These propellers widely used for lower RPM motor and slow-flying drone models. 7045 propeller designed with length in 7 inches and the pitch 4.5 inches per revolution. The wide and thin blades of the propeller in their size category make them highly flexible in crash conditions. Thus they do not break easily. 7045(7X4.5)Propellers Black especially draws the larger amount of currents and as a result, gives us a considerable amount of thrust.
The propeller 7045 consists of a set of counter-rotating RC aircraft propellers. It is perfect for use in twin and multiple motor RC airplanes or coaxial RC helicopters. 7045 pack consists of 2 propellers with adapters (1 CW and 1 CCW). One of the propellers rotates clockwise CW and the other prop rotates counter-clockwise CCW (1 left hand & 1 right-hand rotation). It is quite difficult to find matched rotor blades to matched counter-rotating pairs. These adapters allow the propeller to be used with motors of different shaft diameters.
Moreover, the 7045 propellers used with brushless motors with an 800-2200 kV rating. The propeller offers smooth flights with longer flight times perfect for FPV and aerial photography while using a low kV motor(800 – 1400 kV). Whereas with a high kV motor (more than 1200 kV) this propeller offers fast flights perfect for acrobatic flights. These Propellers provides high endurance and flexibility for great impact. Thereby helps to improve the air-powered efficiency and aerofoil stability.
