You directly pointing to popular EMAX 2822 Motor. 1047 prop will better but 9050 prop will give you 550gm+thrust (1200kv). If 2822 1300kv you have, you have to cut throttle at 80%. Only 39 gm. 2812 motor will give you 600gm+ with 9050 prop but with 2S only, and with 3S, you have to limit throttle at about 60% with same prop for safety.
