Anybody have an easy way to convert emaxx to truggy?

Besides Promod, has anybody else replaced the tranny with a center diff yet? Anybody run into problems with having no slipper? Any kits available yet? I'm thinking of going to center diff only also, but would like to find a center diff that was actually ball diff to allow for slight slippage to protect the drivetrain a little.
