Not disrespect as I don't know the 100% story. But I knew chop from Xbox and on here. He had health issues. Yes fumes are dangerous but that's not the reason completely he was fighting illness for awhile . Just trying to enjoy his love which may have made it worse but it wasn't just the fumes I think. Chop was a cool guy and helpful. Wishes to his family and grandma. Now the fumes are bad, motorama was canceled for nitro because people got sick a few days after because the ventilation wasn't good enough. That's y it's on e allowed now.
