Larry I never understood why nobody listens to you in this thread. You've contributed so much to what the car is today.
Personally I love the concept of the slipper spool and find it to work perfect. Never had problems ever with it other than the first inital few runs when I realized it was too tight and broke pins/lcd couplers. We've even contemplated trying to make one for a different car since it worked so well. Love the dual d rings instead of the copper and regular diff ring. Thanks for that. I've been running the car with all losi parts other than the Parma bumper, lunsford 1' turnbuckles and mcmaster thrusts. Oh wait. You contributed most of these.
For those running the solid spool. Here ya go. Stock up. LOSA3335
