2s quadcopter for 2 inch or 51 mm propellers powered by two 1s 300 or 450 mah BT2.0 batteries and a dji o4 video system with a lens mod from Khorm. The project contains Step. files for milling a 2.5 mm carbon fiber frame and printing files (I used Esun TPU-LW for large parts and TPU for AMS for the connector)

This is my first project like this, if you have any questions or suggestions please write a comment, the frame can be easily used for an analog, please write the mounts for which cameras and antennas you would like, as well as suggestions for mounting the battery and the power connector.

screws for motors m2 4-5mm 8pcs (for mounting with 4 holes)

Screws for the flight controller m2 15-16mm 4pcs

screws for the posts and the upper plate with a hidden head m2 6-8mm 4pcs

Inspired by Kayoumini, I wanted a 2-inch version, but I wanted to add more battery space and also add space for the flight controller tail from Betafpv

At the time of the design, I did not know about the existence of RATE 20W. At the moment, I would consider purchasing it.
