Here's a 1:24 scale Autobot I created using a 1993 Ford Mustang model kit and a Bionacle and Neo Shifter skeleton.
My brother owned a '93 Mustang and wanted me to build him a movie style Transformer based on his car.
The Mustang model kit was cut up into over 100 pieces, sanded, cleaned, primed and painted and then attached to a modified and painted skeleton made from Bionacles and Neo Shifters.
It does not transformer but it does have over 20 points of articulation.
He stands about 10 inches tall. That would make him nearly 20 feet tall in the real world. Pretty close to the size of movie Bumblebee, I guess.
Thanks very much for taking a look and for any comments you might like to share.
