The “Flex-Rite†Tweak Station has two aluminum platforms connected by a steel rod (if you look closely in the picture, you’ll see it running underneath the guide tongue and motor). One platform (the one under the front wheels in the 2nd picture) is leveled (using 2 set screws) and rests on a flat surface. The metal connecting rod is secured to this platform using a couple of set screws. The second platform (under the rear wheel in the picture) pivots on the connecting rod. There is a collar on the connecting rod with a long set screw that elevates the second platform allowing it to pivot – it is hidden under the motor in the picture. The distance between the platforms is adjustable to accommodate different length cars/chassis. A bubble level indicates if the second platform (again, the one that pivots) is level.
Using the rolling chassis shown in the picture as an example, the front two wheels rest on the stationary platform. The second platform pivots on the connecting rod to touch both rear wheels. If the bubble is in the middle of the level, life is good – your chassis is not “tweakedâ€. If the pivoting platform is not level, your chassis is “tweaked†and needs to be repaired/adjusted - the level will show you in which direction. Examples of possible causes might be the chassis itself is not “straight†(left/right) or one/both axles might not be parallel to the platforms (which represent the racing surface). As you build the car, it’s an easy way to check the chassis is “flat†and everything is one the same plane. If you’re racing and have a hard crash, it’s an easy way to see if the chassis was “tweaked†and is no longer flat.
