    ONLY Brian Raffa can handle the 490 death grip

    Okay thanks for the info. its a 90 model just didnt know which would run better in a 300ft drag a big bore ported tri z motor or a ported 490 motor for the money . I was thinking about putting a banshee on there but didnt want to mod the frame . this way i would have both motors to still fit . u cant beat everybody.
