I am not Mandun and I made this Hayabusa with the help of Sketchup.I haven't downloaded it from 3D Warehouse.I saw this same model of this Hayabusa in the 3D Warehouse and I took its Screenshot and by looking the Screenshot,I created it.

looks like mike caught you. i downloaded both the models (splatter g's model and man dun's model) in mandun's model i exported it as skin mesh, and compressed it with winrar  and came to this conclusion that both these models were the same (99.9%) as there was hardly any difference between the sizes of the compressed files and there is hardly any difference between the screenshots. so according to my investigation both of these models are the same.hence proved.
