I just got to race mine sunday and i am impressed with both the truck and the Vspec i run in it. I had some trouble tuning it so a friend got it tuned for me and WOW! I got to re-learn how to drive. I am running stock losi clutch but picked up another 8T for backup and it came with a King Heads 6061 med alumnium clutch set, not sure of springs yet but was told its perfect for a Vspec ( he run it sunday and destroyed a truggy/buggy field) I also got a 2500 aa 5 cell pack that fits perfect in the battery box. Its set up like a 4 cell cage with a cell on one side, it lays down in box perfect
