Default FuntanaS 3D 90 Service Notice

Hangar 9 FuntanaS 3D 90 (HAN2675) Service Bulletin

The Hangar 9 FuntanaS 3D 90 has been designed for extreme 3D flight performance. It is a large model that is extremely lightweight and has large control surfaces. Because of the high performance nature of the FuntanaS, special precautions in the equipment choices, set up of the model, and flying technique are required to prevent damage to the model.

· Use of a larger than recommended engine can cause excessive weight and airspeed, which can result in structural failure.

· The large size of the “3D” control surfaces requires powerful servos. The servos used must be 50 ounce inch torque or greater. JR 811 or 9411 servos are recommended.

· It is necessary to seal the aileron and elevator hinge gaps to help reduce chances of flutter. Clear Ultracote (HANU887) works well for this.

· Proper mechanical advantage on all control surfaces linkages is extremely important. Use of longer servo arms or shorter control horns will reduce the mechanical advantage and servo power available to the control surface, which will cause flutter.

o The recommended servo arm length is 1” or less as measured from the center of the servo output shaft to linkage connection point. JR heavy-duty arms work well for JR servos, part number JRPA215.

o The distance out on the control horn from the control surface should be 13/16” or greater.

· The FuntanaS 3D .60-.90 is not designed for high-speed flight. Throttle management is critical in a model of this type. Do not perform high throttle dives. If the nose is pointed down, bring the throttle back. It is highly recommended that a large diameter, low-pitched propeller be used keep the speed of the model down. An APC 16x4W prop is recommended for the Saito 100 engine.

· The balance point as listed in the manual at 7 1/8” from behind the leading edge of the wing against the fuselage is a neutral CG point, and is the balance point for extreme 3D performance. For more stable flight performance, with reduced 3D ability, move the CG forward as desired.

I hope this was posted in the 3D forum as well. Maybe a reference to this thread should be added to the review. Good info!

Can't wait to see what startsvis has to say about this. He thought that the Funtana 90 was "defected". Ah, I'm just a rotten antagonist!

Thanks Danny Snyder. Good advice. I will add to be careful when assembling as to not damage the wings if they are tight on the wing tube. Someone wrote something about using car wax on the tube and it works great.

Regards all,
Jim

Danny,

I have just read a products review on the U-Can-Do .90 and the author of the article states all the same things you have equated to the Funtana.

Thanks Danny, this is exactly what needs to be put in the manual or on the box itself on a big red sticker.

I agree, 50oz servos will work at the minimum, but will struggle to do it somewhat. If the above directions are followed then the 50oz should work, but the model will need to be operated at an even slower speed.

Good work,
DTB

Thanks for the heads H-9 up. I spent the morning digging into planes I have looking for better servos for the ailerons. I will be replacing the Hitec HS 77 low profile With some Futaba S9204 Metal Gear just to be on the safe side. Found one S 9252 digital as soon as I can afford one more I will switch to them.

Kenny, if you press on the stop light above his name he just goes away.
