Pink Stiffy

thingiverse

A lightweight quadcopter design utilizing hollow arms and a monocoque chassis for optimal strength and crashworthiness was the objective of this experiment. The goal was to achieve improved stiffness and handling while maintaining the same level of crashability as my previous Gnat design. To accomplish this, I designed the quadcopter to be printed in PETG with 7 x 20 mm motors, a recycled Nano QX flight board, and 300mAh 1S Lipos. This setup would allow it to handle most camera/transmitter combinations available on the market. While ABS or PLA might not be suitable for this design due to their limitations, PETG has proven itself capable of withstanding numerous impacts during indoor racing events at our local group. The hollow arms, only 1 mm thick tubes, have surprisingly survived crashes into gates, walls, and the ground. Here are the print settings used: Printer: Qidi Tech 1 Rafts: No Supports: No Resolution: 0.25mm layer, 4 perimeters Infill: 20%
