Designers of r-t-r plastic chassis have had to choose between either designing a rigidly positioned front axle, or having a 'floating' axle, which, by leaving a vertical gap around the front axle, allows the axle to move vertically. This second solution unfortunately not only puts the axle in an unnaturallly low position when the car is lifted from the track, but does not allow any tuning of the relative play between the axle and the chassis.
Now, the new Slot.it Step 3 design enables the racer to tune the front axle ride height and vertical play, while at the same time preserving the correct appearance of the model car, if so desired.
How does it work? Currently, all Slot.it chassis are designed to support the front axle by means of two small moulded plastic down-stops, incorporated into the chassis. With the STEP3 chassis, the height of these down-stops has been reduced by 1mm and removable hollow "cups", 1mm thick, have been pressed onto the down-stops, thus keeping the axle in a fixed position, or enabling a 1mm vertical translation when the "cups" are removed.
The hollow cups come in 4 different sizes, which respectively enable 0, 0.25, 0.50, 0.75 mm of vertical play. The cup cannot pop out, being limited in its vertical movement by the front axle.
All future Slot.it cars (Nissan, Mercedes) have been designed with this (patent pending) feature in mind; the Porsche 956 and 962 will take advantage of the same technique in the near future, as well as the Audi, for which the Step 3 chassis is now available.
