Torque rolls, rolling circles, harriers and more. With Hangar 9’snew FuntanaS™ 90 3D ARF, the only limit to the aerobatics it can perform is the pilot’s imagination. The FuntanaS™ 90 is a larger version of the popular FuntanaS 40 3D ARF and was designedexclusively for Hangar 9® by Italian National Aerobatic champion Sebastiano Silvestri, an expert F3A and Freestyle master and world-class Tournament of Champions competitor whose flying skills have amazed aerobatic fans worldwide. It’s even based on Sebastiano’s famous KatanaS TOC design.

Slow-speed handling is awesome, thanks to the unique tapered constantthickness airfoil and the wing fillets, which add more lift. By using an airfoil section at the center of the wing that is the same thickness as the airfoil at the tip, the FuntanaS 90 3D has stable low speed characteristics much like a large giant-scale aerobatic plane, yet still flies faster precision as well as a pattern model does. Plus, the very large control surfaces give the FuntanaS unbelievable control authority, even at very low speeds. The extremely light all-wood construction also contributes to its no holds-barred 3D performance. The FuntanaS 90 is an extreme 3D aerobatic airplane with extreme potential for performing the most creative, spinetingling moves in any experienced pilot’s repertoire. Waterfalls, blenders, parachutes and other spellbinding maneuvers are well within the range of its abilities.

This .90-size knockout is covered in exclusive Hangar 9 UltraCote for the finest look and protection, and, using a Hacker brushless motor and the enclosed installation instructions, it can even easily be adapted to electric power. The 2-piece plug-in wing makes it a cinch to transport from the workshop to the flying field and back again.

For the wildest and most extreme 3D maneuvers that can possibly be imagined, the FuntanaS 90 3D ARF can handle them. And pilots will look awesome doing them.

Product Support Tips

What servos should I choose?

The FuntanaS 90 requires a minimum of 50 ounce inches of servo torque for each surface.  The JR 811 is a good choice, the JR 9411SA will provide optimum performance.

What radio system should I choose?

You can use any 4-channel radio system or above.  A computer radio will allow you to set up the aircraft easier, and allow you to further refine its flight qualities.

What prop works well with the Saito 100 on the FuntanaS?

An APC 15x4 or a 16x4 wide blade, part number APC15040W or APC16040W, work very well.

What engine should I choose?

Choose the lightest weight, highest power engine you can find, within the engine recommendations. The Saito 100, SAIE100, is a very good choice for this plane.

Section 3: Aileron Control Horn Installation

Step 4

When aligning the control horn on the aileron, be sure that the 3 mounting holes are all over the hardpoint in the aileron, so that the 3 screws will thread into the hardpoint.  The hardpoint is visible through the transparent blue covering.  You can drill the front 2 screw locations at an angle back so that the screws will go through the hardpoint.

Section 6: Installing the Horizontal Stabilizer

Step 5

Pay special attention to the cautions in the manual, which mention not pressing hard with the knife when removing the covering from horizontal stabilizer. If it is cut to deep, it will fail.

Section 7: Installing the Vertical Stabilizer

Step 3

Use care to not press too hard with the knife when removing the covering from vertical stabilizer. If it is cut to deep, it will fail.

Section 13: Landing Gear and Wheel Installation

Step 3-7

Your kit may contain 2 - pre-drilled holes for the wheel pant screws.  In this case, in step 3 mark both positions, step 4 drill both positions, and in step 5 install 2 blind nuts in the wheel pant.  Then in step 7 attach the wheel pant with 2 - 4-40 x 1/2" screws.

Section 15: Engine Installation

Step 2

As the note states, you can rotate the carb 180 degrees to have the needle come out the top of the cowl.  On a Saito engine, you can do this by removing the two carb screws, rotate the intake manifold so the carb will clear the engine, rotate the carb 180 degrees, rotate the intake manifold back to position the carb on the backplate, and re-install the 2 carb screws.

Section 16: Throttle Pushrod Installation

Step 5

With standard size servos it is necessary to raise the throttle servo approximately 1/4" to clear the stringer on the bottom of the fuselage.  You can do this by gluing 2 pieces of 1/8" light ply on each side to the servo mount to raise the servo, or 1 piece of 1/4" ply would also work well.  Be sure to glue the ply to the servo mount well.
