The 2011 racing construction regs are now published in the regs section.

Although there are no changes to the regs, the table of blades and limits, that comply with the existing 2008 regulations has been populated and updated with the limits for each blade type, including the 6Z. This table is for covenience meaning users do not have to do the maths to find the limits for each blade type.

Users of the 6Z in particular, should ensure they comply with the published limits for the 2011 season.

Anybody interested in reviewing the maths behind the calculations, please contact me, and I will happily send you the spreadsheet with all the background data.
