RE: e Sachs 3.2 prop question
jmclain001 , Scale or not so scale, its your call . If you want a 3 blade to replace your 2 blade and are happy with the rpm range you currently have .
Drop 1" in diameter and increase 1" in pitch for a reasonably close match . You probably wont find a 11" pitched prop so a 21x12 would be the closest match to
your current 2 blade prop.
