This is a version of Skimbal's Turtle Shell Racer High Power, slightly modified to work with the New Bright #1680 model RC car. The original called for #2424 which does not seem to be available any longer. #1680 is available at Target as of this writing (May 2012)
All the original files have been run through netfabb to fix slicing errors. There are a couple of new files and/or modifications needed - see the instructions.
Mine is mostly complete, but I'm marking this as a WIP for now until I get it finished.
