os 32, futaba servos, futaba mechanical gyro, 4.8v battery, heli has some upgraded parts and aftermarket accessories. Comes with starter wand, Futaba 6ch radio, and some extras. Helicopter wont start as it needs a new fuel tank and fuel lines (it leaks). It has been sitting for about a year and has not been used. I charged it all up and everything works. Engine turns over fine.
