Toy airplane, essentially characterized in that the axis of the friction drive wheels, has a gear wheel mounted integrally with an intermediate pinion whose shaft is integral with another gear that performs two functions, one of them driving a flywheel to through a pinion coupled on its axis, and another by actuating a third gear wheel whose shaft protruding on both sides, coupled coupled flexible shafts made of metal worm, which adopting the appropriate curvatures and bends, end mounted on the tips of both axes whose ends protruding from the front part of the airplane, are fixed to the propellers, so that the movement of friction of the wheels and advance of the toy, simultaneously causes the found turn of the propellers located on the sides of the airplane and protrusions by the wings of the same.
