Fly the figure-6 with a half-roll down

Fly the figure-6 with a half-roll down

For many, watching a precise aerobatic routine is almost like watching an aerial ballet, and to the aerobatic pilot, there is no feeling that is more gratifying than executing the perfect flight. However, flying a rather flawless routine boils down to not only having a properly tuned aircraft, but also having a firm understanding of your ability and what is required from each individual maneuver. All complex maneuvers develop from rather simple variations, and this month, we’ll discuss a maneuver that takes elements from both the roll and an outside loop.

A figure-6 with a half roll down is maneuver 15 from the 2013–2014 precision aerobatics Masters sequence. Let’s get started!


With respect to the low-rate settings of an aerobatic aircraft, I prefer to start off with 25 degrees of aileron deflection with 25% exponential, 20 degrees of elevator deflection with 35% exponential, and 35 degrees of rudder deflection with 50% exponential. Once I’m in the air, I can make any changes necessary to cater to my specific preferences.

During the figure-6, the elevator is a key control surface as it will be used for a majority of the maneuver. First, the aircraft pushes to a vertical downline where a half roll is performed. Then, you’ll execute ¾ of an outside loop to exit the maneuver upright. If the elevator is sensitive, you’ll have to fight the aircraft, which you don’t want! You also don’t need an excessive amount of control surface deflection for this maneuver. If using you use 20 degrees of elevator deflection, which is a great starting place, use exponential to soften the feel of the aircraft as it responds to pitch commands when the control stick moves from the neutral position outward.


This move is known as a turnaround maneuver as once executed, it will change the direction in which the airplane is travelling. During this maneuver, you should orient the aircraft parallel to the runway, flying upright at an altitude of about 600 feet. The altitude will differ depending on the size of the model being flown, but an altitude of 600 feet will suffice for an aircraft that has a 60-inch span. After the heading has been established, the model should perform a 90-degree push to establish a vertical downline, where a brief line segment will be flown. A half-roll is performed during another line segment, equal in length to the first. The aircraft will then execute a 3/4 outside loop and exit the maneuver in upright level flight in the opposite direction in which it started. This maneuver can be divided up into four steps:


Fly the figure-6 with a half-roll down


STEP 1: While the aircraft is travelling at a fairly high altitude into the wind and parallel to the runway, decrease the throttle and gently push to a vertical downline and fly a brief line. To ensure that your lines are equal, it often helps to count “1, 2” during each segment.

STEP 2: Next, perform a half-roll at a moderate roll rate and fly another line, equal in length to the first. Again, count out, “1–2.” Note that your count will only work if the speed of the aircraft is constant! Make any necessary rudder corrections to keep the flight path of the airplane parallel to the runway.

STEP 3: At this point, increase throttle as you begin the push for the 3/4 outside loop segment. Throttle input will vary depending on the power-to-weight ratio of the aircraft, but it is safe to say that about 75% throttle should be used as soon as the airplane is inverted and passing the 90-degree segment of the 3/4 loop, which is a total of 270 degrees.

STEP 4: Once complete, the aircraft must be travelling in upright level flight, but in the opposite direction compared to the entry. Throughout the maneuver, various aileron, elevator, and rudder corrections will be required; apply these inputs as needed to keep the airplane properly positioned.

To perform this maneuver with pure excellence will require practice, patience, and the proper aircraft setup. Pilots often have difficulty with line segments not being of the same length and may have loops that are not round or a half-roll that isn’t centered on the downward segment of the maneuver. Also, wind can often become a troubling factor. In short, no matter what wind direction is present, the flight path of the model should always be either parallel to the runway during the entry and throughout the 3/4 loop or perpendicular to the runway during the downline segment with a half roll. If this isn’t done correctly, the airplane can easily be pushed to an undesired heading.


It is important that you don’t become frustrated when trying a new maneuver, as consistency comes with time and practice. Before taking to the skies, think about the new maneuver in detail and know what control inputs will be required. When you’re trying out a new move, it may not look pretty at first, but continue to practice until it looks perfect. And, of course, always remember to have fun!
