Particularly on larger or faster aircraft, control forces may be extremely heavy. Borrowing a discovery from boats that extending a control surface's area forward of the hinge lightens the forces needed first appeared on ailerons during World War I when ailerons were extended beyond the wingtip and provided with a horn ahead of the hinge. Known as overhung ailerons, possibly the best known examples are the [[Handley Page Type O]] (first flight 17 December 1915), [[Sopwith Snipe]], [[Fokker Dr.I]] and [[Fokker D.VII]]. Later examples brought the counterbalance in line with the wing to improve control and reduce drag. This is seen less often now, due to the Frise type aileron{{clarify|date=August 2012}} which provides the same benefit.{{Citation needed|date=August 2020}}
