Artsy circles, in a square frame
Two long tracks and one fast track. The fast track is, of course, the loop d’ loop with 7 inversions. Both tracks two and three have ball collecting tipping arms. These two tracks criss-cross each other through a flat spiral, a regular tipping arm, wavy tracks and lots of back-and-forth action. All three tracks collect into the flat plate on the bottom right to get funneled back into the lift. This RBS sports a helical lift and 1-1/4″ balls.
I particularly like the frame on this one. The square that holds the circles looks nice, to me anyway.
