From the developer:
VertiSim is a 3-D simulation of the immortal Mattel toy from the 1970s, the Vertibird. If you had (or wanted one) of these toys as a kid, you'll appreciate this program.
In addition to simulating a Vertibird, my program also has the added twist of being able to place the pilot inside the helicopter cockpit. Very cool! Think you're good? Try picking up the astronaut accessory from inside the helicopter!
