3" Quad-plus frame inspired by the strong tetrahedron structure. Using carbon plates only 1.5mm thick, it can support a 5kg weight on the top arm motor mountings without bending. In other words, it is extremely resistant to (vertical) vibration. It should be noted, however, that it is not strong enough to resist a direct hit by a hard object from the side against the arm or brace (standoff).
Necessary hardware : M1.4x3.5mm screw (Qty 16) and M1.4 nut (2.5mm wide, Qty 16). Please note that this frame kit does not support 3mm wide M1.4 nuts.

It is also recommended to use M1.4 washers and Loctite or similar.
