The BA prop came out about 2003 and has restrictions of RPM and/or MP, as noted in Vans Information and notices March 2003. This was blade 7496.
The new BA blade is 7497. This newer design was a rumored to not have RPM limits. I called Hartzell and they said this is not correct. They have not tested so there are no limits published.
As far as performance Hartzell says the new BA blade 7497 is as good or better than the original BA bladed 7496.... Others say there is a hit on performance.
