Flight Control Technology (FCT) allows you to adjust your launch angle by increasing or decreasing the R11 driver''s loft by 1 degree higher or 1 degree lower. Eight FCT positions allow you to adjust the loft in small and precise increments.Adjustable Sole Plate (ASP) technology allows you to set the face in a square position or open or close the face angle by 2 degrees. After the loft of is set with Flight Control Technology, change the look at address by rotating the Adjustable Sole Plate. An advantage of ASP is that it allows you to independently tune face angle without changing loft.Movable Weight Technology (MWT) alllows you to tune the driver''s center of gravity to promote a draw or neutral ball flight. Putting the 10-gram weight in the heel and the 1-gram weight in the toe moves the CG closer to the heel to give the R11 a draw-bias, which promotes a right-to-left ball flight. Putting the 1-gram weight is in the heel and the 10-gram weight is in the toe moves the CG toward the toe, making the R11 neutral to promote a neutral, or straight ball flightThe advanced aerodynamics of the clubhead allows wind to flow more quickly and smoothly over the crown to reduces drag and increase head speed.The contrast between the white crown and black clubface makes it easy to align the R11 accurately at address. The matte white finish eliminates hot spots and glare to promote improved focus. The white head looks larger to promote more confidence and a fast, free swing speed.
