Overview

Artistic aerobatics is an increasingly popular form of aeromodeling expression that awes audiences with its mixture of showstopping aerial maneuvers and dramatic musical accompaniment. To keep up with the intricate maneuvering involved in artistic aerobatics, a special airplane is needed.
Enter Hangar 9's new ShowTime 4D 90 ARF, a unique Mike McConville design equipped with innovative new SFG Technology—removable Side Force Generators that provide extra rudder authority and control to help perform a virtually limitless display of extreme 3D and precision aerobatics. These Side Force Generators attach to the middle of each wing and generate the necessary lift at low angles of sideslip to excel at slow knife-edge flight. They can be removed in seconds and flown without, as well as to make storage and transportation of the ShowTime convenient.

Also contributing to the ShowTime's extraordinary performance is its lightweight laser-cut all-wood construction, making the plane very easy to control. The carbon fiber landing gear is much lighter than aluminum, yet quite durable and provides plenty of strength for rough landings. The plane looks incredible in its colorful UltraCote trim scheme, and the wide variety of engines such as Saito's FA-100 and Evolution's 1.00NX ensures every pilot will find one that’s right for him. It's the greatest "Show" on Earth—the ShowTime 4D 90 ARF from Hangar 9.

Detailed Information

What are SFG's?
By Mike McConville
The short answer is, SFG= Side Force Generators. The longer answer is SFGs are wing-mounted surfaces that enhance the yaw force created by the rudder. While SFGs really aren't a new concept, adding them to the wing of a monoplane to generate extreme rudder power is a new twist.
SFGs aren't hinged control surfaces. They don't move with a servo, and don’t need to. Their position, size and shape, when correct, generate lift in the yaw axis whenever the rudder is moved. This means the "side force" that is normally created by moving the rudder is enhanced….a lot.
SFGs aren’t new. Ever wonder why some biplane designs, such as the Ultimate, have really powerful rudders? The primary reason for this is simply that they have rather wide interplane struts. In addition to providing needed structural integrity, these struts function as SFGs.
Borrowing on that idea, my good friend and aero-genius George Hicks came up with the idea last year to create an electric-powered foamy for the first E-TOC that had super rudder authority. From that idea the now legendary Tensor 4D biplane was born. Owing its super-rudder power to the exaggerated wide interplane struts, the Tensor showed all of us just what wild aerobatics could be achieved by using SFGs. After the Tensor, we experimented with SFGs on various small foam monoplane designs and had similar results to the Tensor.
SFGs open up a new dimension in 3D aerobat­ics. With them, knife-edge flight requires almost no positive fuselage angle. Even very tight knife-edge loops are possible. Flat spins are more like stationary pinwheels. Control in hovering is also greatly improved. The next logical step seemed to be to put them onto a full-blown bigger model and see what would happen. The result is the new Hangar 9 ShowTime 4D. The easiest way to describe the new ShowTime is that pattern plane meets foamy. Very smooth, precise and easy to fly, yet capable of almost unimaginable extreme 3D maneuvers. So, SFG technology may not be a new concept, but when added to the world of 3D aerobatics, they open up a new dimension in extreme flight.
