in October 2020, I bought a Chinese carbon fiber mast. And I wanted to make the fuselage out of aluminum. But since the mast came up to a square stainless steel pipe. I made a long fuselage of 115 cm. And it turned out perfectly. I experienced it today. The wind was terribly torn today, then strengthening, then weakening of the wind gust. The long fuselage makes the foyle very stable.
