Some new option parts are available now from Team Associated for the RC10B74.1 and RC10B74.1D buggy. Replace steel CVA cups with light-weight aluminium or tune the slipper clutch power delivery with the 3-Pad Conversion. Replace the centre CVA cups with these Factory Team 7075 aluminium versions over the kit steel type to shed rotating weight (4.7 grams) for faster acceleration. The 3-Pad slipper conversion is a complete parts set to change a RC10B74.1 slipper from the kit 2-pad slipper to a 3-pad slipper clutch. The kit design is a 11mm I.D. pad with a heavy 500lb/in spring, ideal for high-load carpet, while the 3-pad conversion is a standard 19mm I.D. pad with a softer spring, which delivers a smoother throttle feel with slower engagement for racers wanting a softer clutch feel.
