Aerobatic maneuver question
 

I have looked and I cannot find what this move is called.. From level flight you pull verticle, do a 180 degree roll pull back to do loop and at the bottom you are going opposite of the direction you started from. I have seen A-10's do this move in airshows showing how it can shoot at tanks and turn right around shoot them again in a matter of seconds.

RE: Aerobatic maneuver question
 

A half reverse Cuban Eight will do what you describe, but I don't know why the vertical part. The Cuban Eight goes up at about 45 degrees, then the half roll and half loop to level. [sm=confused.gif]

Sounds like a one half cuban eight. Wayne

What the two above said. Half cuban 8

there are no vertical lines in a 1/2 cuban


sounds more like a figure 9 to me

RE: Aerobatic maneuver question
 

Exeter is the closest yet but still wrong/incomplete. Cubans have no vertical lines as he said.
A figure 9 is a 3/4 loop which often leads to a dirt-nap.:D
The described manuever is referred to as a "Humpty Bump" with a 1/2 roll on the "up line". It's a common manuever in both model A/C and full size aerobatics.

Wouldn't that be a Cuban 4?

RE: Aerobatic maneuver question
 

Could it be a "P" Loop, but that would be a 1/2 roll on the up line,then the loop and exiting out going the oposite direction. If you did a full roll on the up line, you would be pushing over the top of the loop and exiting inverted.

No P.
As said: Humpty Bump, which have options... This is one of the options.

RE: Aerobatic maneuver question
 

We don't know if Eric97217 meant absolutely pulling up to vertical or just pulling up. The maneuver described sounds like a simple split S to me (also called a Reverse Cuban Eight). The fact that he alludes to A-10s using this maneuver to quickly reverse direction makes me think he's describing a Split S, also. Since it's difficult to describe the movement of an object through space, unless he better describes what he's seeing/doing, we'll never know.

Humpty Bump

Simply because when he says pull verticle to me this means strait up and not at a 45 for a split s

RE: Aerobatic maneuver question
 

Humpty Bump Turnaround: Flying straight and level pull / push 1/4 loop to verticle upline, perform 1/2 roll,
Pull / push 1/2 loop to verticle downline, pull / push 1/4 loop to straight and level in the opposite direction of entry.
Can be entered and exited from upright or inverted.

Options. Flying straight and Level pull / push 1/4 loop to verticle upline, perform 1/4 roll, pull /push to 1/2 loop
to verticle downline, perfom 1/4 roll, push /pull 1/4 loop to exit straight and level in opposite direction as entry.
This is a cross box option which allows the pilot to move the plane either closer to or farther from the flightline.

This is a narrative of a Pattern humpty bump, Imac and full scale may do it different in regards to roll placement.
The humpty bump can also be done in the center of the aerobatic box which you could omit the rolls or add another
half roll on the downline, or change the direction of the 1/4 rolls so you exit in the same direction as entry.
No matter how the maneuver is done it will look like and upside down U.

RE: Aerobatic maneuver question
 

But how would this allow an A-10 to be lined up again on the tank he just shot at? I had a chance to watch the Indiana Air Guard fly over a practice field and they performed a reverse Cuban 8, but not one that you would want to have judged :D. Still its an impressive aircraft to watch fly, and amazing maneuverability considering its size.

In a true Split-S the model performs one-half (1/2) roll in level flight then immediately executes one-half inside loop to level flight in opposite direction as entry. The reverse Cuban 8 requires a pilot to pitch the plane up.

This sounds a lot like it. I guess I should have been clear.. from level flight, straight up, while going up is the half roll, then the half loop, coming out level and in the posite directions. Thanks for the insight!
