Hello Robert

I just found that building report and thought it could be interesting for you:

Good luck with your Do 24,

Timo

Hi Timo,

I have just gone through the build and what an interesting build with such attention to scale detail.

I see I'm on the right track with the thoughts that I have had regarding the rudder operation and a few other things including concealing the cable runs in the cabane struts.

I had done a bit more drawing this week and I'll post up some more photos soon.

Regards

Robert

Hi All,

Just got off the drawing board and thought I'd show what I have done so far.

Details of the nacelle construction, I'm using the same technique as I did on the Condor.

Rudder operation is by a single servo driving a piano wire through the stabiliser. I came across this method when I looked at my B25 Marutaka kit which I was going to sell but after looking at it I might just keep it and build it some time, although I have been thinking this for some years now.

Rudder horns made from brass tube and epoxied into the rudder

Still thinking on how to operate the elevators at present

Fin and rudder construction, although may opt for sheet for the fin

dsc02341.jpg

Tailplane and elevator ribs

Next, the spnsons and wing ribs

That's all for now

Regards

Robert

Thanks Tony, the hardest part is getting it all to work out, thinking in 3D as I call it, certainly drains the brain cells after a few hours.

Hello Robert,

Just found your thread. I have deep resprect for your devotion to this project. Making a design for a this aircraft without and limited reference is very challenging without cad.

Currently i'm working on a 1/10th scale Do24k. I did many research to make my design as scale accurate as possible. Im am willing to share my archive with you. If you like this please sent me a pm.

Here is a link to my thead on RcGroups : **LINK**

Below are some pictures of my project.

Davey, Bart said 1/10th scale, so I make that a span of 8ft 10in, in 'old money'

This is a fabulous project, the cad drawings could be framed and hung on your wall (although my wife might have something to say about that teeth !

Some lovely drawings Robert, looking forward to following the build. I remember seeing a model DO24 in RM magazine many years ago, of about six foot span. It was powered with a single glow two stroke, the outer two faux engines just windmilling in the breeze. How things have moved on...

There is a picture of the DO 24 in the May 1984 edition of Radio Control Model World.

Referred to in the magazine as an unusual prototype.

This model is equipped with three Saito 40 four strokes driving three blade props.

No wingspan is quoted but to my eye it looks about 100 inches when looking at another photo of it among other models on the water.

Could have been that one Tom but I thought it only had one engine and it was photographed on it's own, not with other aircraft. But then it was a long time ago!

Hi All,

Managed to do the sponsons today as well as some shopping.

dsc03282.jpg

dsc03280.jpg

i moved the rear tube forwards as the rib was too thin for my original position and I have kept it the diameter as the front.

dsc03279.jpg

Bought the cowls, perfect diameter with a good radius on the bottom with a nice thick wall. I used these for my FW 200 Condor.

dsc03283.jpg

dsc00142.jpg

which when painted look the part

dsc00109.jpg

I had hoped to get a lot more done over the weekend but time has just gone.

That's all for now

Next, the wing ribs

Regards

Robert

Nice work Robert ,

Carefull with the sponsoon profile. It is very importand to keep it 100 scale. If the sponsoon profile is wrong the hull will never get on the step becuase of the suction in the water.

The bottom has to be as on the drawing below. The red line is the angle of the bottom in relation to the keel.

Cheers,

Bart

Hi All,

I have had several distractions that have taken me away from the Dornier, most of which have been completed (wife had a list of jobs to be done before xmas) so paint brushes washed and put away.

I have just ordered up the balsa and ply. I'm hoping to start building just after xmas.

That's all fro now

Regards

Robert

This one was in RCM&E many years ago and featured a single OS80FS.

I have often fancied a project like this but time and commitments has made this impossible - until now!

Looking forward to following your build progress in the New Year Robert.
