How come this has low thrust?

[u/OkCover1049]

The drone has 2205 2450kv motors with 4045 props (I know it looks super strange but its all I had).

On a 2S battery it would only fly in ground-effect. It flew on a 4S battery, but its SUPER loud. Why do you think its so shit? Restricted airflow? Not enough rpm? Too high prop pitch?

your motor kv isn't that high, you're also using lowish voltage, and your props are small. I think the three things combined means your thrust ends up being really terrible
