Review on 🧱 Ravensburger GraviTrax Expansion Multi 27601 by Andrew Dinelli

I installed it as a starting point for my Trax system. The balls pass through several switches before returning to the launcher base. This allows me to easily throw multiple balls into the system at once and watch them zip through the lane configuration. Because all the balls are returned to base, it's easy to restart them again (and again). Placing a black vertical block and a piece of rail in front of the launcher will allow you to line up a row of spheres for the launcher. If you need a connecting part, you can remove the green switch from the switch and merge the two traces that way.
