yeah metal works nicely. if you read through the clutch lsd thread youll see that i posted my experiences with different materials and different designs. i took the metal washers from a little 4wd tamiya
paper = rough
plastic = binds
metal = nice and smooth
would a stock motor with timing advanced and water dipped count as stock still?
with the driveshaft idea i cut one of my penshafts so it was a little stub and it held on to the bearing. the gear moves around a little because the bearing doesnt seat in the yellow thing tight enough. any more ideas on making the car faster by not modifying the motor or board? lightening the drivetrain even more?
