Scratch built this sucker out of some spare dust bunnies I had laying around the place. Being she will run on off the rails I had to steal some servos, suspension parts and steering mech. off an old 1/24 radio control stock car I had laying around. The power plant came out of an Atlas RS3, has the dual flywheels, "this baby purrs like a kitten". All that took up more space than originally figured. She came out to about 12" equals 12" scale.
