I will be purchasing the Cap-X w/ the OS 160 FX...what 3D prop should I use. Brand does not matter. Thanks for any advise.

The APC 18x6W is 4.5 ounces. The Zinger Pro 18x6 or 18x8 are only 2.2 ounces. The point is that I'd go with a wood prop for 3D. That will give you the fastest transition, key to 3D flying. The Mejzlik 18x6 and 18x8 work well too but are heavier and more expensive (carbon fiber).
Here are some great threads on prop choices for that engine. Prop it for 8500 to 9000 peak RPM.

Do you not think that the lighter props suffer from a lack of thrust thats inherent to the larger APC's and CF's? I am seriously considering trying a Bolly and also the Mezjlik but have not read any conclusive evidence them being any better than the heavy PC I currently run.
does anyone know a good online retailer to purchase the Bolly from? My lHS has the Mezjlik already so ill buy that from them

Mejzlik 20x6. Weigh of CF prop is between that of wood and that of composite, so transition will be a little better than APC. You should get 20 lb. of thrust with this prop, swinging in mid 8k. Some people have this combo and really like it. But depending on your ground clearance, a large CF prop is not cheap to maintain.

A 20 inch prop is WAY too much. 19 inch is pushing it.
I have ran 18x6 PRO ZINGER and APC, both with good 3D results on a 12.25 pound airplane

RE: OS 160 FX 3D Prop!
I have not had much luck with a 160 FX (all on 13lbs planes and above). It does not have that low end torque I require in 3D. I tried a bunch of props nothing came out great. Try to get the plane under 12 lbs then it will work well. I have seen it on a QQ YAK 54 and at the lighter plane weight it fine very fine :-). In other words try a lighter plane not lighter props.
