CARF Models B-2 Spirit Bomber

The **B-2 Spirit** is a stealth bomber aircraft developed by Northrop Grumman. It is one of the most iconic airplanes ever built, with a gorgeous, slick, all-black stealth design that combines the coolness and menace of Batman and Darth Vader into one deadly package for the American military ¹. The B-2 Spirit has an impressive size of 435 cm wing span and a length of 21 m ¹. It is powered by two General Electric F118-GE-100 turbofan engines, each producing 77 kN of thrust ¹. The B-2 Spirit is capable of carrying both conventional and nuclear weapons, and has been used in several conflicts, including the Gulf War, the Kosovo War, and the Iraq War ¹.

CARF-Models offers a highly prefabricated ARF kit of the B-2 Spirit, which is all composite and painted ¹. The kit is designed to be easy to transport and store, and is big enough to impress the crowd with an unprecedented appearance in the sky ¹. The center fuselage/wing has the tricycle landing gear, 2x 100 N sized engines and RC components installed. They are accessible through 3 large hatches and 3 large gear doors, all readily installed and hinged ¹. The fuel system is installed through 2 large bomb bay doors on the bottom of the fuselage ¹. The two wings slide onto 4 aluminum tube stubs and carry all flaps for elevator, aileron and rudder control ¹. The CARF-Models B-2 is controlled using a simple delta configuration of 2 flaps in each wing, which controls elevator and aileron. Optionally, the tail cone of the fuselage is mixed into the elevator function as well. This is set up using a high-end 3-axis gyro such as a Powerbox Mercury or similar. The rudder gyro function is used for the nose wheel steering, which is important for this airplane with no fin. The aerodynamic yaw stability is achieved by two drag rudder, positioned at the outer wing tips, which split open 25-30 degree during all flight, and just like the full scale, create drag at the furthest point behind the CG, stabilizing yaw perfectly. Those split flaps are used for yaw control by opening and closing the split angles alternately. They can also be opened and closed simultaneously within their limits and work as speed brakes during landing ¹.

I hope this information helps!
