Thats for the 1100kvt motor. he's got the 1400 kvt motor. I'd start ~9x6 and watch your amps.

they give the list of prop test:
8x4 - 14.8v - 251W - 17A
8x4 - 11.1v - 121W - 11A
9x6 - 11.1v - 178W - 16A
9x6 - 14.8v - 355W - 24A
10x5 - 11.1v - 200W - 18A
10x5 - 14.8v - 385W - 26A
11x5.5 - 11.1v - 200w - 20A
12x6 - 11.1v - 266w - 26A
According to that 12x6 is suppose to be possible.
If I can have a little bit more power with that motor and the 10 x 5 original prop so that knife edge is possible (with the stock motor and 9x4.7 prop it look to be not possible)
