XRAY - Model racing cars

All the xray drivers at our club have all switched to the yokomo bd-189L belt, and have had no problems since. Much stronger, and you can run at maximum loose setting with no issue. The standard belt breaks too easily, will need to be modified next year. Running the belt tighter is not an option in 17.5 blinky you loose too much top end speed.

I'm sorry Salinet for being a pain in the a**, but I still don't understand what do you mean by "middle to tight"? Starting from the middle position (initial instruction manual position), how many steps left or right (tigher or looser) is that? Today my colleague also snapped his belt, his was in middle position, as is mine in the moment. Tomorrow is race day, and I will try with horizontal position (not upper or lower, the softest position) or the one tighter than that, since the belt has had a few runs (initial manual middle position) and it's already very worn on the side.
