We were generally happy with the arm design this year. Our problems with it at WPI were chalked up to a lack of driver practice and coordination: you need that to grip the tubes in an ideal location. Also, our PVC arm had a lot of flex which contributed to an already harder-to-control long arm system.
Of course, 330's ace in their sleeve is always their driving, so I guarantee they will do amazingly with this design. |
There is a 12" stroke, 3/4" bore air cylinder tucked inside the arm which extends and retracts it.
We had used PVC back in 2005 for the arm, but for rigidity and ease of mating components (square aluminum extrusion for lower portion of arm), we opted for a fiberglass tube. We are using the same fiberglass tube for 2011 as we did in 2007.
