Re: [FTC]: Question about the chains

Tensioners in the middle of a chain run can help substantially to minimize this potential. 17 inch wheel spacing is a dimension we have used with a single tensioner, and with good sprocket alignment, we have lost only one chain in 14 years of competition. That happened in the days BB (before bumpers), and the chain took a direct hit from another robot frame.
Hodge,

This is a FTC thread. The driving forces and speeds are a lot lower than with FRC motors.

In general, they should have no problem or need only a rudimentary chain tensioner.

Regards,

Mike
