I have a Saito 72 on my Ultra Stick 40. Performance has been good, but the vertical is not great. I have tried several props, but I am currently using a APC 13x7. My best performance seemed to be 12x6 Master Airscrew, but I was concerned that it was not enough of a prop.

I would appreciate hearing about props others may have had luck with on the Saito 72. Also, do you use 15% nitro?

Thanks!
