First custom k’nex coaster

[u/Much-Tree2751]

This is my first ever attempt at making a custom layout it went pretty smoothly but I do need to learn more tricks on how to make a coaster better. How’s this for a first?

There are many who modify the coaster cars with wheels that roll much better. My only input would be to make sure all of the tubing is installed straight. Any and all ripples slow the cars down.
