Have you considered a center diff? Do you really need a slipper, or can you live without one? If you have a decent transmitter, you can add expo to the throttle. Or, you can use the punch control in your ESC. Either way, you can work around a slipper, and eliminate it... if you're willing.
ive played with the punch control in the esc and it has helped alot. the real problem im having is that the slipper gets so hot it melts the cent out of the spur gear. maybe i will just try to find a metal spur and be done with the slipper all together
