neubie need engine size explanations
a .15
traxxas just used that number to make it sound big. dont get it. the engine sucks. it is great for 2 gallons and its downhill from there. in the tmaxx it is way overstressed from the weight and stuff. it is great for the other traxxas cars though, as from what i understand. soon im going to be dropping in a .18 sirio or a big block conversion chassis. i cant decide though. the big block will cost nearly $650 when everything in the drivetrain is bulletproof.... oook straying off topic.
anyways, hp really means nothing in rc. its more of the torque curve yous hould be after. if the engine reaches its peak (1.6 lets say) horsepower at 35,000 rpms, then it will more than likely be horribly weak at moving a big vehicle since it would have no low rpm grunt.
