About this Plan

Mini Funtana. Radio control sport aerobatic model, for Park 400-size motor. Wingspan 37 in, wing area 329 sq in.

Quote: "The original Mini-Funtana was an ARF from E-flite, introduced in 2004. It was designed for Pattern aerobatics and featured a re-positionable wing that, when placed in the forward position, makes it suitable for flying extreme 3D maneuvers. It has been discontinued for many years and parts are unavailable. I acquired a much-bashed model that needed rehabbing. There are no plans available anywhere, so I carefully measured my example, looked at the pictures in the Assembly Manual, and looked at the damaged areas, and created plans in CAD. I have incorporated some reinforcing (thin plywood and carbon fiber)..."

Update 02/11/2018: Added parts layout PDF and the ARF Manual, also CAD plan file in dxf format, Thanks to DMorris.

Quote: "I see that my plans for this model have been added to your site. Great! I would like to post all of my plans at Outerzone.

There is a parts layout plan in PDF format and a .DXF drawing, which is a text-based file that is interchangeable amongst many CAD systems, and can be used with laser cutters. And there is a PDF of the original manual from E-flite that has setup tips and the control throws. They are attached.

Here is a picture of the original E-flite Mini Funtana.

And a note: The wing ribs shown on the Parts Layout Plan have been modified with a snap-off tab to support the ribs during construction. The wing has a unique design in that the rib thickness is a constant 1 in, meaning that the thickness of the rib increases (as a Percentage of the chord length) as the ribs get shorter due to the wing's tapered shape. Thanks."

Note the model pic currently shows an ARF Mini-Funtana, as that the closest image we have at the moment. When someone (hint hint, DaveH...) sends us a pic of a model completed from this plan, we'll use that.

Update: 03/11/2018: Replaced the parts layout PDF with revised version, thanks to DMorris.

Quote: "Then early version that did not have the snap-off tabs on the wing ribs and the fuselage sides would not be laser cut correctly when burn allowance was factored in, so I redrew that sheet using wider stock.

Also a suggestion: because of the carbon fiber reinforcement, it is possible that the receiver antenna could be 'blanked' by the CF. To minimize this, mount the receiver low in the plane on a scrap of 1/16 balsa mounted on the fuselage’s bottom stringers, then poke the antenna through the covering to point straight down. "

Excellent drawing!

What an absolutely superb job, in every way! A joy to look at and work with. I'm fortunate enough to have easy access to a wide format printer and laser cutter. The plan is printing right now, the laser will be fired up shortly, and building will start today. Thank you all!

Doh. I have now put the DXF file where it should be, inside that previously empty CAD zipfile. My mistake.

Notes

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.

Scaling

This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
