In drivetrain i use 2 XL. There are no any speedups in vid, but there are two different gear rations from start to 1:12 and from 1:12 to finish.

About shoes - I broke my toe on the right foot some days before
I don't think about instruction yet - car is not finished, I'm going to do some changes...
