After the 2016 1:8 scale World Championships, the Area 51 engineers began working on an idea to make Team Associated’s clutch system more easily adaptable to changing track conditions. After months of prototyping and testing, they came up with a patent-pending design that gives racers the ability to adjust the tension of the clutch springs — without having to remove the clutch and change springs. In fact, the engine doesn’t even need to be removed from the chassis to make the adjustment. The adjustment is done with a single set screw that engages with a spring cam. By loosening or tightening a set screw in the flywheel, the spring cam rotates within the flywheel to adjust the tension on the springs. This means you can make quick adjustments while in the pit lane.
To make a clutch adjustment, bring the car into the pit lane, shut off the engine, make a quick adjustment to the clutch set screw that engages the spring cam, and fire the engine back up. This is especially useful when track conditions change and you want to tune the power band to get the most comfortable power delivery.
