HPI bodies are not intended for the racer they are ment for showing they tent to be week in high stress areas. if you have a hpi stratus body just watch how much the rear folds at speed from the stress placed on it from the rear wings wind restance and downforce causing unpedictable handling at high speed and that can be very bad at the end of the straight. WACK OUCH!
as the driver says justing the boards making sure that they are tight lol
