Super nitro is a 1/8th car and it doesn't look like it has the super's body mounts and the shocks are on a steeper angle... My guess is that its a RS4 2 nitro racer the only thing missing is the carbon upper deck. The only way to know for sure is checking the chassis (posting a pic of the bottom) and or measuring the wheel base. Reg RS4's are 200mm width and obviously the Super's will be wider 280mm to 300mm.
