Ultralight Helicopter

The LEGO® Ultralight Helicopter (set 42057) is a 199-piece LEGO Technic set released in 2017, capturing an aerodynamic one-person helicopter in a sleek white, red, and black livery. The model features spinning main and tail rotors driven by a gearwheel, a controllable tail rudder operated via joystick, a detailed engine with moving pistons, and an open cockpit with a detailed seat. As a 2-in-1 build, the same bricks rebuild into an Experimental Aircraft for a second model. A uniquely decorated Technic 40th Anniversary brick is included, marking the line's milestone year.
