The 1-23E has 52.8 foot wings equipped with balanced dive brakes.

It features dive brakes on the bottom of the wing only, but externally-mounted.

The Ranger is not equipped with any glidepath control devices, such as dive brakes.

No dive brakes, flaps, nothing to slow up the plane.

This feature avoided empennage buffet when the dive brakes were open.

The machine was also fitted with dive brakes for dive testing.

And with dive brakes, you could have done that.
