I can say the TrailBlazer are a tougher then the blasters. I used mine for trailriding for 2years then it was used for MXracing an trail riding then modded it m ore an just MXracing an modded more an was racing the 240 blasters Mxracing an was beating them that explains my 2003 sportclass champion in sig. I weighted 215lbs an was racing guys on blaster in the 150 to 180 range. An I am there 15 to 20 older then them won it at 36yrs. Blaster are a good fun little quad but I belive the TB will last longer with less trouble.
