Parametric tilted motor mount for quadcopter

//****
//Motor mount tilt for quadcopter.
//
// Each mount consists of an upper piece that
//goes above the fram arm and another piece that
//goes below the frame arm.
//This will keep mounting screw lengths the same
//mounting screws will have no angle force on them.
//****

I achieved only a small top speed increase from using tilted mounts. Please report your results if you try this.
