The Hangar 9 Carden Aircraft Edition Yak 54 ARF is a shrunken version of the popular Carden 150cc Yak 54. Carden Aircraft participated in this endeavor by working with Hangar 9 to provide their construction techniques, drawings and designs to be used in the creation of the Hangar 9 Carden Edition Yak 54 ARF.

This level of completion is beyond comparison in the giant-scale market. The kit comes highly prefabricated with the fuel tank assembled, hinges and control horns installed and hinge lines sealed. Constructed from durable, lightweight balsa and foam and covered in genuine UltraCote®, the Yak 54 ARF also boasts a balsa truss fuselage construction and balsa sheeted foam-core wings that is Carden Aircraft construction to a tee.

In addition to the unparalleled level of completion, the Yak 54 ARF also has smart design features such as a two-piece wing and stab—standard on all Carden kits—that ensures convenient storage and easy transport to the flying field. Also included are top-quality, durable components like the fiberglass cowl and lightweight aluminum landing gear.

At Hangar 9 and Carden Aircraft, we know how you want them to fly—and nothing less than first class is acceptable.

Three important design factors of a great flying aircraft follow. This plane is well designed in all of these areas.

1) Low pitch coupling - when the rudder is applied, most aerobatic planes pitch to the belly. Reducing this is extremely difficult to do. The relationship between the thrustline, wing location, stab location and rudder shape are critical. Typically the stab is located on the thrustline, the wing is just a little low, and the rudder area above and below the thrustline is as even as possible. If incorrectly designed, serious flying problems result. When you are flying straight and level and you use the rudder to adjust the flight path, or if you are flying knife edge, or if you are simply flying a loop and you are using rudder to stay on track, the last thing you want is the plane to pitch down with the application of rudder. This can be controlled with mixing in a computer radio, but cannot be eliminated in all aspects of flying. If the plane isn't designed for low pitch coupling, then it will be a real handful to fly precisely.

2) Low roll coupling - when the rudder is applied the plane may roll. This is due to the dihedral in the wing and the shape and position of the rudder. The more the dihedral the more the plane will roll with rudder (called proverse roll coupling), however, too little dihedral will make the plane roll the other way (called adverse roll coupling). This must be designed in during the prototype stage so that there is none. This can be designed into any aerobatic plane. Just the same as above, when you apply rudder, you want yaw only, no pitching, no rolling. This really shows up in slow rolls. You will noticeably see the roll rate of the plane speed up and slow down when you use the rudder. This makes you look like a bad pilot.

3) Wing Loading - the relationship between the weight of the plane and the size of the wing. When you get a plane, starting off with a plane which comes out light is the first step. Starting with a heavy airframe is difficult (and expensive) to overcome. Keeping weight to a minimum is critical to many aspects of performance. This is something that the designer has control over - but the pilot can have a large influence on this as well. When we recommend parts to the pilot we suggest the lightest parts possible.
