I just got this for 500€. Came with a free towel : ) Do you think the mast is hollow under those back plugs? Not sure if they are just at the top or going through all the way like a resin cast.
I can still return it. Seems very solid to me. The mast is tiny in crosssection. Those are M8 screws, so the total width is maybe 12mm. The fuselage is solid and the mast mount cnc milled. Good quality overall. Not sure if I can fit big cables in there.
