i\Randy had a standard rotation 3 blade carbon prop , I dont know the origin,,
the first 13x4.5 was labeled a P,, the newer one was the EP,, and then they reissued the P as the F2B,,, there is about 1200 rpm difference between the two types on y setup,, I currently turn about 11,300 with the P ( F2B) and was over 11, 450 with the EP
by the way,, you have progressed a lot since the last time you came from church to beat me LOL,,
