Rad Runner is a Gravity Group running PTC trains. I set out to build a coaster borrowing heavily from Legend and Rampage (CCI coasters) and Thunder Run (a DIN coaster), but I shaped it a bit too fluid and smooth, and the result felt like a GG. The helix area is the main element of this coaster, with exciting lights and stronger laterals. I used the LPC to make the crosstie supports and used a lot of community-made content for lights and atmosphere.
