Hi!
Drone experts,
Can u please share info regarding..

"""Weight carrying capacity """

of generic kit with
1000kv, 2200mah 3s, 10x4.5 prop, kk2.1.
Thank you,
regds.

Honest opinion: Just fly it as it is, You don't want to carry any weight even if it's 50g payload with those generic things.
Your parts are generic and have questionable reliability, so you would be putting yourself and others in harms way when carrying payload.

Ideally a 450size quad could support upto 150g payload safely and not to exceed more than 1.2kg maximum take off weight (MTOW).

Mohammed Naveed
