Crossing a DIII with a DH9a
« on: August 24, 2025, 08:40:08 PM »
Whilst working on the small details of my main project I kept looking at the pile of other Pegasus Albatros kits on the shelf and thinking what am I going to do with those  :-\

Re-reading an old Windsock magazine I came across an article about building an Albatros DIV and couldn't get it out of my mind so, just for fun, I decided to make up a kit of bits.

Mine's based on the Pegasus DIII kit and because the original Airfix DH4 wings that were used in the original article have now become collectors items on Evilbay I used parts from a KP DH9a instead (I bought a much nicer version after buying the KP one so it was just languishing there) ;)

DIII - DIV by Paul S, on Flickr


As you can see in the above view the DIV was a test machine that was never intended for production. It used a 160HP geared Mercedes that was completely enclosed in the nose so with no engine or gun details to worry about hopefully a quick little side project; it even used a three bladed propeller at one point (as well as two and four bladed ones) to try and cure vibration problems. The three bladed one appeals because I was asked at a show earlier in the year about three bladed props and it will also help with the 'similar but different' look  :)

The flying surfaces were larger than standard (Hence the Dh9a wings) The tail will probably come from a scrap of Gotha wing and since the fuselage has a different layout with the cockpit moved further aft and the nose lengthened I can utilise the original kit parts with some modifications (Lopping 3mm from the tail, adding about 6mm to the nose for a start) I also think I can use a slightly modified fin though so it's not all bad news. A pair of ex Eduard seat and headrest as well as a Roden exhaust and wheels from the spares box completes the parts list (I may also add some interior using a PART etch set since the outside will be pretty plain . . .

These kit bashes are right up my street so I will follow this one with interest.

Nice one Paul!
I have also collected parts for an Albatros D.IV: A D.V body with D.II wings & struts and W.4 tailplane, all by Roden. Of course this doesn't cover all the changes, but it's a start.

Thanks Alan.  :)
Hopefully not too involved . . . ::)

Cheers enathan  :)
I've gone with a DIII body because the plan in the Windsock article I'm basing this one on shows flat sides which I tend to agree with looking at the photo's, but maybe a DV as suggested by J Herris is the way to go  :-\ (My logic is that the DV body and aileron set up would have been 'new' in April 17 whereas the DIII was proven and would have been easily available for this engine test bed) Who knows for sure . . .

I'd never heard of the D.IV until this thread. What a neat idea for a kitbash, I like it! I'm eager to see your updates as and when.

A very intriguing project that will be a great talking point when you display this one. Looking forward to this.....

     Nice work. I've done one once, following an ancient article by IIRC Ray Rimell, possibly the Windsock article you mention, and back then the logical starting point was a Revell D.III, which isn't that much like a D.III to begin with anyway.. This actually looks like it'll make for a better result with less effort.

Thanks Zac, Nigel and Stephen  ;D

Probably the same article as you're thinking of Paul (From summer 1988 edition) ;) I've also found that a full set of plans (including bottom and second side view appeared in the Windsock Special 'Albatros Experimentals'.

The tail from a bit of Gotha wing didn't work because by the time I'd sanded the symmetrical aerofoil the chord was too narrow. Instead I made the tailplanes from the offcuts of the wing tips that were left over and I'll sort the elevator later. Now the bench is completely covered in dust it's time to finalise part shapes and finish sand the bits. Incidentally I've found that filling any control surface gaps by gluing in a piece of stretched sprue works better than the usual filler since it is less likely to crack out at a later point.

I've removed the prop blades from the spinner in anticipation of a carved three blader (This is one occasion when a solid spinner is helpful since I can carve my own slots to suit) Usual dremel thinning of the fuselage sides means I might even be able to use some PART bits to dress it up later (No interior photos of this one of course so layout is anyone's guess, but I'm assuming it will be generally similar to the DIII/V)

I'd forgot about the Experimentals volume. Some nice stuff in there.

I also forgot to say I'm finding this build log very interesting, and it's nice to see alternative uses for the old Peggy kit. I have a handful left over from Freightdog, which were very, very cheap at the time.

Thank you chaps

Tempted by some of the later experimental types in the book as well Paul  ;)

LOL Nigel, that's exactly what I am.  ;D Time to clean up the workroom (again)

Cool subject Paul ! 

I do a fare bit of filling seems and gaps with plastic rod or bits of sheet , Sands better , smooths better , and easier to plend in that seem . Looking forward to your next up date .

Thanks Alexis, good to hear that someone else uses the same technique  ;)

Anyway sanded down the wings now and separated the ailerons with the torque rod added form a piece of brass wire. Smidge of filler needed where the two pieces join (brass wire pins ensure a nice strong joint. Next up will be scoring the wing ribs with a scalpel blade as on my other builds

Just for fun here's the Dieter Collins DI wing with scored ribs, the standard Pegasus DIII wing and the new DIV one showing the increased chord and different shape (Slight scallops in the trailing edge will be added after the ribs are done)  :)

The wing is looking good, and that's an interesting comparison between the wings.
