Apologies for being 5 years late!!
I have mine in a H9 Ultrastick 120 Lite. I found the 18x6 Master Airscrew had bags of static thrust, but lacked airspeed. I felt it was about to fall out of the sky!
I then changed to a 17x12 APC and it's a peach now. Will tach it on the weekend for you.
I also flew it with a 16x14 APC with similar good results, but preferred the 17x12.
