Way more motor than you can use. I use to run astro FAI motors with 12 cells. Those were 5 turn motors as I recall. Man its been 20 yrs. I used to run direct drive with 1750 or 2047 props. Real fast but just was no class back then. That motor you have can take more prop than you can fit on that lower. Good luck. Hell the worst that can happen is itdont work.
