3d printed nano longrange FPV drone

This is a simple 3d printed frame for a single 18650 powered FPV drone. The frame weighs only 10g, overall weight including 18650 LiIon battery is around 97g. Flight times are +19min. I think it is feasible to get well over 20min as the temperature was around 5C during the test, I stayed on the stock PIDs and the VTX was set to 100mW.
