ROLL TIDE!!
I'm kinda partial to the Hyper 7. I think it looks better and IMHO Ofna builds a better buggy especially if your going to be racing. I'm not sure there is even a class For the HPI Trophy. I would go by your local track and see what there mostly racing first before investing in something. More than likely your going to find stadium trucks and buggies to be the most raced.
