50mm frame quadrocopter

This is my next attempt to design a micro brushless quadcopter 50mm from motor to motor. I also did not print this thing !!! (i don't have a printer). Yes, and I have not yet figured out how the camera will hold)))
Parts that are useful for assembly:
Brushless motor 11xx series (DP03 inserted in the models will also be 1103) like this: https://www.banggood.com/ru/EaglePower-SA1103-Lite-1103-6000KV-8000KV-10000KV-2-3S-Motor-for-RC-Drone-FPV-Racing-p-1242994.html?rmmds=search&admitad_uid=0403be
