Dornier DO 26 Seeadler
I made decision to build one of most beautiful seaplane as I know.
Dornier DO 26 Seeadler.
Because I do not have much time I have change strategy how I will build.
I created model in computer and then asked my friend to do it with CNC technology.
As I discovered CNC technology is very good technology but need a lot of preparation before something is done in machine.
Probably because it cost time to think how should be shape of part done with cnc technology.Anyway now I am able to reproduce each part because everything now is in electronical version
I was use three type of machine:
1. 3d cnc milling machine
2. 3d cnc cutting machine for wing from foam
3. 3D printer REPRAP
I hope I will add some picture.
I have started to do this last year but because lack of time I would like to share with you some pictures.
Basic parameters of model:
Wing span 2000 mm for my toyota corolla car .
Power 2 electric engine ala axi 2826 ...
Rest 2 engine I will not mount.
Weight 4500 g.
Battery lipo 5000 4SP1

Outcome from milling machine
One of my friend is very smart and build at home cnc machine with dimension 1500x2500x200 mm.
The machine is so huge and we tryed produce my parts.
Here you can see outcome.

Former posts were done last year 2012. In this year I have made some progress too.

Completaion of centrolplan and wing
Now came time to complete some parts.
MOst parts fit perfectly and they save a lot fo my time for measuring.

I do not have experiences with polystyrene because I normaly build wing from balsa or plywood but water is not good for balsa. That I choose plastic material

Now I want to check dimension because it last time when I can change something.
I was using laser . It is more easy way how to checked . I do not have proffesional laser but I think it is enough for me.
One think each part is from different collor of polystyrene . It is because shops sometimes do not have sizes which I required . Unfortunately quality is different .
Now is almost everything done before covering everyting with epoxy L 285. The shape is very complecated but cross finger that everything will done ok . I hope because I aked for help one of the big laminator in Czech republic is Venca.

One of most complicated parts is mechanism of folding of folat to wing.
I thinking about it a lot but I am not very happy what I desined.
First I am using mechaism for normal landing gear.
I build arround it holder of float.
From my point of view is too complex.
Original seaplane has diferent but I am not able produced it.
Here is simulation how it looks like with rela mechanism.
It is getting me crazy how I will solve this problem.

Beautiful aircraft and model.

I have made some progress with floats.
Float is combinantion of foam and parts made from plastic.
Plastic parts were done on 3d REPRAP.
