Wedges to add dihedral to multirotors

Last crawled date: 4 years, 3 months ago

These wedges allow you to add either 3 degree or 5 degree "dihedral" to quadcopters. Adding at least 3 degrees of dihedral generally makes a multirotor more stable - at the expense of slightly lower airtime. But where stability is important, the results are worth it.
Two versions of 3 degree and 5 degree wedges are provided. One for when the motor mounting holes are turned 45 degrees with respect to the arm axis, the other when the motor mounting holes are lined-up with the axis of the arm. Make certain that the widest part of the wedge is at the end of the arms (making all the props tilt inwards).
Also included are small washers so that the motor mounting screws don't have to "bend" 3 or 5 degrees. You may have to drill the motor mount holes in the arms slightly larger to accommodate the fact that the screws will be going through them at a slight angle.
