Hello, I just started building my first drone a couple of days ago and i got to a point where i feel like I'm at a dead end. I bought 4 esc's (https://www.sigmanortec.ro/Controller-Motor-ESC-30A-p139673260), 4 motors (https://www.sigmanortec.ro/Motor-Drona-2212-920kv-filet-stanga-CW-p139670867?fast_search=fs) and a 3s battery with 2200 mah 30 C lipo battery. I connected all of them to an esp32 and everything seems to work fine, until i try to take off. The motors spin correctly but the drone will not get off the ground. The propellers that I'm using are 1045 ones. If you have any ideas what could be wrong please help me understand what I should do differently.

Quadcopter Parts Failing
Hi, I built my own quad and they work temporarily but parts keep failing and requiring replacement. The battery, motors, ESC have been constantly failing, sometimes releasing smoke! I’ve used different types of components still same phenomenon, which may indicate bad circuit. Motors: QWinout...

Motor kv looks on the low side heavy lift motors are under 1000kv , racing quad 1200kv you didn't say what size frame , so keeping the motors your have to up prop size but quad will fly slow , or up the motors and have a faster quad
Go on YouTube to rcmodlereview there lots on there which will help you also use ecal.com
ecalc.ch
This will tell if it will work or not with motors and props ESCs etc

What do you mean by hooked them to an esp32? Are you using a flight controller? (They are typically stm32 based). Are you using betaflight.... need a lot more detail to really be able to help, try to share a vid (upload as unlisted on YouTube and share a link here) or show some pics and describe exactly what you've setup so far and what you've been able to test in terms of individual components.

Low KV motors like yours lean toward heavy lift rather than speed.Motor kv looks on the low side heavy lift motors are under 1000kv , racing quad 1200kv you didn't say what size frame , so keeping the motors your have to up prop size but quad will fly slow , or up the motors and have a faster quad here
