Default New mini pizza box with K&B sportster 20. what prop?

I just finished building a mini pizza box form the spadtothebone site. I put a K&B sportster 20 on it. What prop do you people recogmend for this plane?

It has been so long since I ran the K&B 20 that I don't remember what prop I used on a 20 size sport plane with it.

Thanks

Concur with 9x4 for a K&B .20, although an 8x5 tends to work well if you are looking for more speed. APC 8x5 runs nicely, especially with the muffler baffle removed.
