I'm having a problem with my DIY drone for a very long time. The problem is that the drone's motors work properly and evenly in the motor test, but whenever I try to operate it with the remote controller, the drone tilts and flips before it takes off.

I'm pretty sure the motors and propeller directions are correct. I also made all the esc and pdb connections properly. I also performed the calibrations. I've repurchased all the parts, collected and mounted them again and still have the same problem.
