1/4 scale Super Ximango/Fournier RF-10

Hello folks!

My name is Charles and I live in Brasília, the federal Capital of Brasil!

I am an airline pilot, flying the A320 Airbus family!

In 2018, I will be completing 10 years of my first flight! It was on a Super Ximango motor glider. A plane built by the brasilian Aeromot, based on the french Fournier RF-10.

Before become I pilot, I used to build electric models, mainly using fiberglass. But because of all the studying and high load of work, the builds had to be halted!

But recently, I moved to Brasília where I am based now, and finally have a little bit more of spare time. So, I decided to build from scratch the Ximango!

The scale is 1/4, so the wingspan will be 440cm and fuselage length about 205cm.

I started the project build a 3d model on Blender(blender.org) and printed the sections to cut the MDF to make the plug. Them, I will make the molds.

The model will be built using composite materials and I hope to finish this saga in less than 2 years!

I created a page in Portuguese to post the building process to my friends watch: www.facebook.com/tecnicasdemodelismo.

This is a movie showing the beginning of the construction:

Any comments and help will be very appreciated.

Strip planking

Continuing with the build, I cut the sections of the fuselage and glued on the longitudinal plane.

To get everything as straight as possible, I clamped the fuselage on two sheets of MDF, that were cut with a CNC machine.

And now, the strip planking started. I am using a 4mm plywood.

Strip planking


I removed the half of the fuselage from the template and continued the plating with plywood strips.

Then, I used a laser level to check if the longitudinal axis alignment is correct and I think it's fine.

It will still take many hours to finish closing the entire fuselage, but by now, you can see the size that will be. I'm excited about the result!

Next step will be fill in the spaces with poliurethane foam.

Hello guys!

In recent days I got access to photograph and make measurements of the Super Ximango that is in the air club of Brasília, in Luziânia. It's about an hour from my house.

Now with the measurements in hand, I can make the model much more like the real.

These are some of the photos I took.

I also put in the messages above a link to the videos I made. They are narrated in Portuguese, but I did subtitles in English and I hope these videos can be useful.

I'm trying hard to document all the building in videos. It may have some delay in publishing because editing the videos gives a lot of work.

And the sanding work continues.

The shape is almost ready. I am waiting for the resin and fiberglass to start making the details.

I believe that the great part of defining the shape is now done. So I applied a thick layer os resin with a yellow pigment.

That will help me control the sanding to smooth the surface. Also, a layer os fiberglass was applied to strenght the whole thing.

The next step will be put some more resin with another color and start sending again.

Yesterday I applied the first coat of PU primer. Now it is easier to smooth the surface, since it is the same color. I believe that at least two or three coats will be needed.
