hi guys me and my friend both have hyper 7 tq sports and we are looking into racing them we bought these as rtr kits and havent modifiyed them in any way as of yet, what hop ups should we get for our buggies to make them race suitable, and what is the largest/best nitro engine that we could put into them

we have heaps of money to spare so price isnt an issue

are these buggys suitable for racing?

cheers mat

the buggies currently have hyper 21 3 port engines
