It also depends on what these people do also . If they are doing stupid jumps and/or landing on the nose or tail , it will bend the chassis fast . The H8 chassis appears to be stronger than my Mayhem and the H7 , and Jammin` I have/had . It took around 15 gallons for my mayhem`s chassis to start to bend with normal racing . My other mayhem it took 6 gallons to bend with bashing and doing 15-25 ft high jumps . Hobao has been around for a while and done their homework and sure the chassis is fine.
