At the same time a fixed fin was added.

At first, the Badger carried almost no fixed fin.

A single fixed fin was mounted behind the wings on a pair of booms.

There was no fixed fin, just a generous and slightly angular rudder.

The second stage has four fixed fins, and four steerable control surfaces.

The rearmost section of the fuselage can be fabric covered but there is no other fixed fin.

The first fixed fin was introduced by surfing pioneer Tom Blake in 1935.

Fixed fins cause the missile to spin in flight and a single moving control surface adjusts its course during this rotation.

The tail surfaces were all-moving, without a fixed fin or horizontal stabiliser.

There was no fixed fin.

These surfaces were fabric covered and the rudder was round topped; there was no fixed fin.

Fixed fins were introduced to surfboards by surfing pioneer Tom Blake in 1935.

As on the Ponnier monoplanes there was no fixed fin but just a rounded, flat topped rudder.

Around 1936, Woody Brown independently added a fixed fin to his second surfboard design, which further popularized the feature.

There was no fixed fin, only a rudder of irregular six-sided (five of them concave) shape.

Enough fixed fin and tailplane was retained to allow aerodynamic balancing via an inset hinge.

A single elevator was carried on outriggers ahead of the aircraft, and a fixed fin and horizontal stabiliser behind.

The fuselage remained deep and high sided back to the tail, possibly offering some directional stability in the absence of a fixed fin.

The IA had no vertical surfaces but small fixed fins were added to the IB.

Fixed fins and bilge keels do not move; they reduce roll by hydrodynamic drag exerted when the ship rolls.

The fixed fin and ground adjustable tailplane were ply covered, mounting fabric covered control surfaces.

As with many other Avia designs, the BH-26 originally had no fixed fin; only a rudder, but this was changed in service.

As on the 41-P, the ply covered fixed fin and tailplane were very narrow, with generous, fabric covered control surfaces.

It had a rectangular balanced rudder with no fixed fin and split elevators attached to a non-lifting horizontal stabiliser.

The aircraft had a fixed tailskid undercarriage, while it had no fixed fin, having a balanced rudder instead.
