Beaver DHC2

A sheet of depron foam and some bits of balsa.
You shouldn't need much more than that to build this half scale model of the legendary Beaver DHC2.
A simple geared Speed 400 is enough to fly it. You can also decide to install a small brushless to have even better performances than with the Speed 400 motor.
It's an easy to build model and it has very good flight characteristics. That's a perfect plane for a beginner or for relaxed flight on a Sunday.

Cutting the parts

The next step is to cut all the parts needed to build the plane. When finished you should obtain a nice puzzle like this:

Isn't it nice? It looks like a kit. The 2 plywood rings shown on the bottom right of the photo should be made with depron foam instead. It will be much lighter.

 

To cut the parts:

Solution 1: You own a CNC cutter

In this case you can download the dxf parts files and import them directly into your favorite CAM software.
But you have to remember that I organized the files depending on my machine and my working habits. You may have to reorganize them.
If you have already downloaded the file DHC2_decoupe_cnc.DXF, you don't need to download each file individually.

Solution 2: : You don't have a CNC.

How can you live without it? Time to build one! you can have a look at the CNC section of this site to find more information.
But for now get yourself a cutter and some new blades!
Most parts are made of 3 and 6 mm depron foam. Nothing really complex here. Just be careful to make clear cuts, assembly will be easier.
The few plywood parts will be cut using a jigsaw.
If you want to use the bitmap files (gif) to print your parts, check that the size is correct when printing them. Full size is achieved wheb printing at 72 DPI. For a better quality printing you should use the DXF files.

The size of each panel is there as an indication. It has a margin of 5 mm around the parts.
