How is a barrel roll performed?

what you describe with full rudder and aft stick would result in a snap roll if the entry was correct. A barrel roll is a coordinated maneuver done on a parabola. The aircraft is first placed in a shallow dive to gain airspeed then as the nose is brought up through the horizon left aileron and left rudder are applied smoothly, coordinated back pressure is maintained until inverted then released slightly, as the plane continues to roll and the nose drops through the horizon aileron and rudder are slowly brought back to the neutral position, back pressure is applied slightly to bring the nose back to the horizon. Done correctly the whole maneuver is kept in positive G. The control inputs are constant feed and released smoothly throughout this maneuver performed about a fixed point on the horizon.

To get a visual idea of what the maneuver looks like take a threaded bolt and look at it from the end, consider the center line of the bolt as your point on the horizon now follow the path of the threads as they go around the bolt. This is the same flight path taken in a barrel roll you enter and exit slightly of course in relationship to the center line of the maneuver.

What Is A Barrel Roll

A barrel roll is a combination of a loop and a roll often confused with the aileron roll, the barrel roll is different

indeed.

From level flight, pull the nose up smoothly but quickly to 45 degrees above the horizon. As the nose reaches the 45-degree point, start a smooth roll (usually to the left) while gradually increasing the pull to start a loop.continue the maneuver by using aileron, elevator, and rudder inputs to maintain a constant, smooth rate of change in both pitch and roll. As we reach the inverted position at the top of the "loop," the wings should be level and the nose should be on the horizon, with our heading 90 degrees from our original direction. The maneuver continues with the nose falling through the horizon as the airplane rolls back toward wings level. The barrel roll ends, like a loop, with the airplane returning to level flight on its original altitude and heading.

You should look around during a barrel roll, which ideally is a smooth, graceful maneuver. Enjoy the view as the world goes upside down, but make sure you look straight ahead as we fly through the top (inverted) portion of the maneuver. It's always cool to see the earth above and the sky below.

As a true aerobatic pilot the easiest way to perform a Barrel Roll, is to lower the nose slightly and gain airspeed. Next you would go back to level flight for a second, then pull the nose up to 30 degrees. After to pull to 30 degrees you need to move the stick all the way over and hold it there until you return to level horizontal flight. You shouldn't have to use any rudder at all if done correctly. If you feel that you need to use the rudder apply a very little bit. The plane is not suppose to yaw during this maneuver, but you can yaw if you feel that it needs it. Practice everyday until you finally get to where you feel comfortable doing them. The you go on from there. Good luck hope this helps.

A barrel roll is a positive G maneuver where the aircraft rolls completely over.
