This report compares the gyro spectra of QingC’s 3D-printed PLA-CF frame and a traditional carbon fiber frame. The QingC frame shows a lower mid-to-high frequency noise floor with only an isolated peak at 120–133 Hz, avoiding the 20–80 Hz broadband noise accumulation found in the carbon frame. Weighing $\approx$ 216 g with a top speed over 120 km/h, it validates the flight readiness of modular carbon-reinforced 3D printing.
