This should be a relatively quick build. It's WW1 and flew - well just about
I started this evening and now have this:

So, what is it?

Cannot tell what it is at this stage, but know how outstanding its going to be once you are done with it..... ;D

Now, this is an unintended consequence of this thread. I'm in danger of getting an overload of fascinating new ideas :D

Too much fuselage covering. Another fascinating aeroplane - thank you

Nice work. The skis look great! Nieuport 10 in Russia with Skis ;D

Love those Nieuport 10s, especially the ones with the pilot in the front and the arched support to the upper wing

A Sikorsky S16 or S20?

Those are nice, especially the s-20

Just the rudder and tail skid to go at the back now:

I'm afraid white styrene is a bit difficult to get good pictures from

I was thinking that I was quite well informed of WWI planes, even of the not so well known ones. But now I have disappointedly to admit that I have no clue at all what you are building here. I know just one thing: If I were that fast with my kit builds as you are with your scratch builds, I could at least double the rate of my finished models .

This is the 1917 Sopwith Aerial Target. There was also a version with four wheels.

Not quite. It's the R.A.F* Aerial Target, the Sopwith one was a biplane. From what I can tell, the four wheel version is from the 1920s experiments

Do click on that image, it's full of detail

Six built, maybe three flown, all crashed. The drawings are online too, somewhere
I have a fascination with WW1 wireless, and this popped up while I was looking into something else. Couldn't resist it

More progress:
(http://www.primrose-engineering.co.uk/wp-content/gallery/at/cowling-1.JPG)
At last, I can show images that include the top of the fuselage!
Vacuum formed engine cowling with balsa former in front.
I have started on the A.B.C Gnat engine. If anyone has a clear picture of the starboard cylinder head of an A.B.C Gnat, I'd love to see it. I can find fuzzy pictures, I can find slightly less fuzzy pictures of the port cylinder head. Starboard - forget it!
Closest I can get is a picture of an A.B.C Mosquito, which apparently had six Gnat cylinders, although curiously with the spark plug moved: http://www.aviationmuseum.eu/World/Europe/Netherlands/Amsterdam/FK23.htm
There are a few Gnat engines still in existence, you'd think the internet could come up with something...

That is a very interesting aircraft that I knew nothing about! Thanks for doing the build!

There are all sorts of oddities in aviation if you dig around a bit. I'm trying very hard not to build a DeHavilland Queen Bee
Anyway, an A.B.C Gnat:

An Academy Clerget gave up two cylinders for this engine. What do I do now with an uneven seven cylinder Clerget?

Next, I need a propeller. I could make one
Has anyone got a 48-50mm clockwise rotation two bladed propeller? It sounds like a reasonable 1:48 size - around eight foot diameter

That Bob Buckles and his infernal bits of wire and scraps of tube...
I've spent two evenings rigging this aeroplane. How can there be so much string on such a small thing??

There's an interesting arrangement on the elevators:
(http://www.primrose-engineering.co.uk/wp-content/gallery/at/rigging-3.JPG)
There was a wire running from the front of the tailplane, over the horn, around the back of the elevator, over the other horn and back to the leading edge. Where the wire meets the leading edge there was a tension spring top and bottom. It looks like the aeroplane was rigged to fly straight and level with the elevator held in place by this wire and springs. There are also control cables running forward top and bottom coming from the servo (whatever that looked like)
To me, this looks a bit of a disaster in the making, I can imagine the elevator would flap about. Looking at the history of unmanned aeroplanes, the Aerial Target predicted the destiny of most of the prototypes - it crashed on take off.
I'm going to have to sort the prop out next

Wow Richard, she is looking mighty fine. Would never have learned about her if not for your build.
-
Looks like another of those strange birds which sometimes get off the drawing board but not off the ground - well not very far anyway. They are still very interesting though and this one is probaly better made that the originals!

Looking stunning Richard! A great build of a crazy concept ::)

Quite a common concept though. From reading around the subject (not easy) this was the second aeroplane Low was involved with. The first had a 50HP Gnome engine who's ignition system interfered with the wireless control. The ABC Gnat engine was designed specifically for this application, which is why the Sopwith version used it. There was a DeHavilland aerial target too, I haven't found anything about it yet
This is the Sopwith Aerial Target:
(http://www.ctie.monash.edu.au/hargrave/images/sopwith_at_1000.jpg)
http://www.ctie.monash.edu.au/hargrave/rpav_britain.html
Which became the Sopwith Sparrow:

http://flyingmachines.ru/Site2/Crafts/Craft25670.htm
The most successful of these would be the Sperry Automatic aeroplane of 1918:

The most prolific the Liberty Eagle, better known as the Kettering Bug:

And for variety and completeness, the Siemens Schuckert wire guided glide bomb:

OH YES...!!

I spent an extravagant 79p on a length of bass wood and made a prop, then found a prop boss on an old etch. This is now about done:

My interpretation of the available information is that this aeroplane was like the early wireless transmitters. It had a trailing aerial, which I think was attached to that plate on the port side of the aeroplane. It would also explain why the Aerial Target had to be airborne before it could be controlled - it had to get the aerial flying before it could receive signals. The image of the AT at Farnborough shows a lot of cable looped up on top of the fuselage in the vicinity of that plate
I'd better fit an aerial

This one has turned out to be as gorgeous as all of your others! I really interesting and unique build!

That is another of your super scratch builds - and another interesting type which I had not heard of before. Wonderful modelling in every way.
Stephen.

Richard, I just discovered your nice little airplane here, what a pity that I missed it!
It is fantastic in all aspects, almost unknown subject, scratch work at all, using wood and metal (I really like the skids, looks really like wood) painting, rigging .... plus a hugs amount of information on history (the Bantam in Amsterdam looks sooo cool) and modeling techniques - thank you for all!
Cheers,
Frank
