Commented Unassigned: Small error in a property [18]

WheelDrivingMotor.cs:

/// <summary>
/// Gets the axis along which the driving forces are applied.
/// </summary>
public Vector3 ForceAxis
{
get { return ForceAxis; }
}

should be:

/// <summary>
/// Gets the axis along which the driving forces are applied.
/// </summary>
public Vector3 ForceAxis
{
get { return forceAxis; }
}

It should return the field not the property again.
Comments: Woops! Thanks for the report, it's [now fixed](https://bepuphysics.codeplex.com/SourceControl/changeset/2a7e42713866).
