I am a fan of the Hellfire. I have owned 2 (a RTR and a SS kit)
They kept up with pretty much all of the high-end truggies out there and were tough as nails.
If they still made the SS kit I would pick up another 1 and convert it to brushless.
My SS had a RB C6 in it that moved! I really miss that truggy.
