i hav an ofna 9.5. the brakes start to fade fade really fast, bout 3/4, the way through a tank. thats y i dont race for the time being. im not sure if theres a definate upgrade for the 9.5 or if i can custom fit the hyper 7 or 8 or 9's brakes the work. below is an old pic. the only thing different is theres a new engine. so thoughts will help. o and the brakes that r in now aren't that old.
