And if you're looking down that list, you'll encounter the 13x6.5 (F2B)
This is the old 13x6.5 I was so happily using. Then I decided I needed some back up props for this year's WCh.
I put one of those to the test, only to find my lap times had dropped from 5.3 to 5.8
After some close inspection the new props appeared different (By then I didn't know of any 'upgrades')
Two e-mails to one of the APC guys made clear they'd made some changes since the time my first prop had been produced.
But he wrote, 'If the old version works better for you, I'll start making that again'. Talking about listening to your customers....
So that's why it's in the list again.
And no worries, in spite of being labeled 'F2B', it will work for AMA CLPA just as well...
