FPV Drone 4"/5"

17/11/2025- Add new version with support for 30.5x30.5 FC/ESC/STACK;I forgot to specify that 3mm threads need to be inserted into the holes of the main body, both the upper and the lower ones.For the engines, screws 6mm long are needed. This is a revised and corrected version of my project to build a small drone. It is suitable for 22xx or 18xx motors with 4" or 5" propellers. The arms can accommodate ESCs or you can opt for a 4-in-1 system. The compartment intended for the GPS is also designed to house an ultrasonic sensor like the Radiolink SU04. It can be printed without supports.
