Which one of your motors is suitable depends on more than just the kV rating. First look at the power output and then determine which prop size you need to generate the thrust you want. A tool like Drive Calculator will help you do that.

You want something in the neighborhood of the AUW in thrust, so 850g+. The biggest prop you can fit is an 11" which might be ok for your 750 kV motor provided it can spin it. With the 1120 kV I measured 850g with a 9x6 and 1040g with a 10x4.

Good luck.
okay thanks ,one more question ,,did you cut the foam right behind the old motor mount?????
