it came with greese in the diffs which was pretty messy to change out, the servos were junk so those got changed. The motor has plenty of power for the truck and any track out there. The truck is very high quality and is a very nice ride. I put diff oil in the diffs and left the shocks alone for the first trip out. I put Airtronics 94359 servos on throttle and steering.
For heavy racing the motor mounts need to be changed to low profile mounts and the spin start needs to be taken off and you need a back plate for the motor for use of a starter box.
Another thing that Losi screwd up on to make money was they only put a 2 shoe clutch in the car stock. So you need to go into the motor and put 2 more clutch shoes in it and you will get alot better bite.
Also, on the radio tray be sure to put the servo spacers between the servo and the radio tray to space the servo from the bottom of the chassis. Also be sure to keep the O-Rings under the radio tray on the chassis and keep a little bit of flex on the radio tray. This will save your servos from getting burnt up. (some secrets from the 8ight-B)
just what ive found so far.
