JETCOPTER : Finished design

About a year back I was contacted by a production company over in LA looking to have some vehicles designed for an upcoming movie. In the end they decided to go with another artist so I didn't get to start, but the description they gave was a helicopter with retractable rotors that turns into a jet. There weren’t much more details than that, so no explanation as to what kind of copter it was. What size or what it would be used for.

Just for fun and to scratch that itch, I did a few very quick sketches of some jetcopters, various sizes and shapes with different kinds of rotors. Just exploring different ideas.

I settled on my fourth idea, a much bigger vehicle with some powerful fold out turbo rotors. The front end is for passengers and the rear for cargo, with a rear door for loading.
I built the copter in 3D and used that for some paint overs.
