Heavy-duty Slip­per Clutch

RC Car Action - - BUILT FOR SPEED -

As with the 22 buggy, the 22SCT 3.0 gets the new HDS (heavy-duty slip­per) clutch to con­trol off-the-line trac­tion and pro­tect the gears when the trans­mis­sion takes a hit off jumps or through bumps. The star of the show here is the large-di­am­e­ter slip­per spring, which al­lows for more of a con­sis­tent set­ting and wider range of ad­just­ment. Its larger di­am­e­ter spreads its load over a wider area, and the larger spac­ing on the coils al­lows for more turn­ing of the ad­just­ment nut be­fore it bot­toms out and locks up the slip­per. The slip­per discs that squeeze the pads are ta­pered, which re­duces their weight. The discs also have slots milled out of them on the pad side; this in­creases their sur­face area, which al­lows them to run cooler and re­duces more weight.
