I went back to my mentor (he has since become a bit irregular due to health issues) and pestered him into giving me a 13x7 APC from his stockpile of modelling stuff. Actually, I was looking for a 13x8 but 13x7 is also good. All my props are MAS, I use them for their longetivity but APC was all he had in that size.

Still too big for a .75!!!
12x7 = OK
13x6 = OK
13x8 = NOT OK.
13x7 = Marginal
