The prompt
Design a compact True-X FPV racing quadcopter frame for 5-inch propellers. Create a symmetrical four-arm layout with four motor mounting platforms, a central electronics stack, an FPV camera mounting area, a battery mounting area, and space for a receiver and video transmitter. Make the design lightweight, mechanically sensible, and easy to assemble. Use rounded transitions at the arm roots and make the arms replaceable. Generate an editable CAD model and provide an STL export for prototyping. Clearly identify the dimensions and mounting holes, and flag any dimensions that require confirmation against the selected components.
