I have the 1.60 on a qq yak 72", i use the apc 18X6w, and I like it. I have tried 18x8 menz and it spools quicker but I think carries too much speed for 3d, I have purchased two skorepa props for this 18x8 and 18x6, haven't tried them yet but I am flying the 22x8 skorepa on a Taurus 52 for break in and it is a great prop, spools very quick and has good thrust, and they don't cost an arm and a leg either. They are from es composites. Brad.
