Wedges to add dihedral to multirotors

thingiverse

These wedges enable you to introduce either three-degree or five-degree "dihedral" to quadcopters. Introducing at least three degrees of dihedral generally makes a multirotor more stable, but it does so at the expense of slightly shorter airtime. However, when stability is crucial, the results are well worth it. Two versions of three-degree and five-degree wedges are included: one for use when motor mounting holes are turned 45 degrees with respect to the arm axis, and another for use when motor mounting holes align with the axis of the arm. Ensure that the widest part of the wedge is positioned at the end of the arms, causing all props to tilt inward. Additionally, small washers are included to prevent motor mounting screws from bending three or five degrees. You may need to drill motor mount holes in the arms slightly larger to accommodate the fact that screws will pass through them at a slight angle.
