hey guys i am having a hard time finding a good sized 3d prop for my 160. Most props that get the rpm range where it needs to be are pattern props and not good for my OMP profile 80 Inch edge. I have tried Master airscrew 20/6 rpm 7100 evolution 19/8 7500 but flies it to fast . Mejlick 20/9 to fast . I was thinking along the lines of a apc 18/8 wide blade or Mejlick 20/6 Running Wildcat heli 30% . Any opinions would be apreciated . Need to rpms up around 8000 to 8500 static.

Sure wish I could help BAS, the only info I could give would be for a Pattern application. The APC 18x8W or the 19x8W seem like the right choice, but never have flown one, I can't say. I have a buddy that uses an 18x8 on his OS 160, but your motor will swing a bigger prop.
