Default YS F120-NC/SC?

Dave,
I purchased this YS 120 form a fellow club member. The box it came in says YS F120-SC, but believe it's a NC. Throttle body bore is 11mm, there is no low end adjustment needle and no throttle barrell retaining screw. I have attached pics. to help identify. Can you confirm this is a NC? I was able to determine these differences form the central hobbies web site pics and some here on RCU.

Also, I'm putting this engine on a H9 Funtana 90. What prop would you recommend for 3D? I'm thinking APC 16X4 wide or a 18X6 wide. This plane isn't a speed demon and I realize with a low pitch prop throttle mangement is a must to prevent overspeeding the engine.

Thanks for the help.

Looks like an NC to me as well.

The 16x4 is too small, the 18x6 too big. Try for a 17x4 or 17x6.
