I broke my first blade the other day and just swapped it out for one of the spares provided in the box (assuming they were all the same). After doing that I noticed that two of the blades are A1 and two are B1, so I don't know what it had on it from original. It now has an A1 and a B1 fitted.
Do you have to have both A1 or both B1 or can they be mixed?
Is there a difference between the blades?
Blades marked A and B are the old style. A1 and B1 are new style with a larger base pin and new style rotor head. A1 and B1's are the same. I have 1 911 with one of each.
