Spin the massive rotors of the powerful 3-in-1 Twinblade aircraft!
This Twinblade aircraft is literally revolutionary! Spin the rotor blades and lift off like a helicopter. Then rotate the engines 90 degrees and power forwards like an airplane while the dual tail fin ensures steady flight. With its red and white coloring and engine exhaust details, the Twinblade is easy to spot high in the sky. Back on the ground, use the ramp to access the cargo hold, and when you want a new challenge, rebuild it into an old-fashioned biplane or a speedy helicopter.
