Not in my opinion, they are actually completely different. Its just an alternate route .. The d8t is a fully race truggy.. it comes as a kit that you have to separately buy a motor, radio,receiver,servos, starter box, and exhaust pipe and battery pack..
HPI trophy truggy is a basher and the d8t is fully race inspired truggy that is built strickly for race.
heres the difference between the two
This is the HPI Trophy truggy... notice how it has large bumpers, not to much attention to CG.. I personally believe you COULD race this truggy but it was most likely intended for bashing.
Here is the Hot Bodies D8T
Notice how there are no bumpers ( because its just for the track and nothing else) also the CG is excellent. Also if you notice everything is all put in the middle of the chassis thats why there is a void of chassis behind the motor. everything is centered nicely.
Its just the trophy truggy is mostly basher
Hot bodies D8T is all race. the reason it comes in a kit is because usually racers when they get a kit like this they want to be able to choose specific engines/servos/radios etc etc.
