90 Years of the DC-3/C47

While researching this story I found myself getting more interested in the 247 story and started one of the old Williams 247s. I have a set of Pointerdog decal sets for the Western Air Express markings. Western got the 247s indirectly from United as United started to cast loose their 247s in favor of the new DC-3s. While not qualifying for this campaign, I thought I would share this build as well as it is an important part of the DC story.

This book filled in a lot of the gaps in the DC story. KLM the Dutch airline entered a stock DC-2 in the McRobertson 1934 race from England to Australia. They flew their regular route with mail & passengers making stops out of their way and at one point even had to backtrack to pickup a wayward passenger. Despite this, the DC-2 beat all other competitors save the customer built De Haviland Comet racer designed just for this race. A modified 247 placed third.

This section below came from the wonderful book above. It should probably be noted that it was not just British military planes that were outperformed by the two airliners. A=The American military was flying P-12s & P-26s at the time!

Hello everybody, not much posted here but lots going on at the workbench. First to the war time C-47 to pre-war DC-3 conversion. I really loved what Airfix has done with their C-47. It’s a great kit of a C-47, but will need some work to be a pre-war DC-3. The early DC-3s used the Wright R-1320 single row 9 cyl. engine which had a different cowling to the P&W R-1830 14 cyl. used by some airlines and almost all military versions.

Happily, I had the Academy B-17C kit in stock and it had two sets of cowlings. To build the C the short cord cowls are wanted and the long cord cowls are surplus and those will be useful for the DC-3. They will need the openings in the front expanded and the cooling gills removed. More on this when I get to it.

I found a set of pre-war R-1820s in resin that ought to be about right for a circa 1937/8 TWA DC-3. They fit the B-17 cowlings like a glove!

Once the workability of such a conversion had been established, it was time to start construction. The C-47s had two crew members added compared to the airline versions. The forward baggage compartment was modified for the use of a navigator & radio man. None of this can be seen if the baggage door is closed so I just assembled it to lend extra strength for the cutting and sanding that will be needed later.

I have no info on cockpit colors so a generic greenish gray was chosen for the flight deck. The C-47 cabin is bare but for troop seats so this area was painted a dark gray to impede visibility through the windows.

The C-47 cargo doors will be puttied over and sanded smooth and I will have to figure out how to scribe an airline door just aft of the widows.

More on this later along with more of the progress on the companion Boeing 247 & Ford Trimotor later.

A bit more work done on the Airfix new tool C-47 to pre-war DC-3 conversion. A lot of time has been spent with Tamiya putty & wet sanding. We are making progress!

I had originally thought about trying to scribe an airline door into the plastic/putty. Then I found that decals of an airline door are available from Draw Decals. I have ordered a set. This will solve one problem allowing the scribing to be just straight lines although still over a curved surface. The next thing to figure is how to know where the lines will terminate so as not to get into the door. BTW, the trooper door of the C-47 is aft of the airline door so it can’t just be modified. I took a look at the Italeri kit which offers a DC-3 door insert panel but they did NOT relocated the position. As near as I can tell, both the DC-3 door & the C-47 cargo door which contains the trooper door are hinged to the same frame.

Work on the early DC-3 Wright conversion continues with successive layers of putty & sanding. It is done but for re-puttying where my attempts at scribing around compound curves resulted in less than great results. I’m dangerous with a scribe in my hands!

I got out the Pointerdog decal sheet that I am going to use. It depicts a TWA DC-3 from 1937. Sadly, I think Pointerdog may be out of business, I haver not been able to contact the fellow that was making these decals in some time.

One of the DC-3 books is below the decal sheet in the last picture.

While working on the Airfix DC-3 conversion I have been poking around with the MPM DC-2 kit and decided that building it concurrently with the DC-3 made sense. The cowlings on the DC-2 will be useful for modifying the B-17 cowlings to be used on that conversion.

The MPM kit is surprisingly good! It is actually better than the new tool Airfix kit in a number of ways. Where Airfix has huge troughs for the panel lines, MPM has restrained detail that is much more realistic. The downside of this is that it is easily sanded off . . .

The cockpit to is better with a very nice instrument panel, not that much of this will be visible once closed up.

The fit is not as nice and does require more work, but not hugely so. The propellors are build’em yerself types, we’ll see how they come out.

Oddly, there are no exhausts in the kit! The locations where they should be are scribed into the plastic but it’s almost like somebody forgot to actually build them.

Here is the DC-3 fuselage in front of the DC-2.

I decided to try something new for me. These aircraft had curtains so I designed some on the confuser and printed them out on colored paper. They were cut out and glued in with Elmer’s School Glue. The light colored one shows what the curtain detail looks like. This model will have Eastern Airlines 1934 markings, before they came up with the wonderful Great Silver Fleet markings which have to be the best airline livery of all time. I do not know what the interior colors would have been so I guessed that matching blue curtains might be appropriate.

The vertical fin & rudder had to tab!!, it was just a butt joint and I hate a butt joint so a plastic card tab was made.

The EAL making will be stolen from this kit which will be built later with a set of TWA marking from Vintage Flyer.

Lots more to report but I’m out of time right now.

Is anyone else building anything? I hate to hog all of the action!

From today’s perspective, it is hard to realized just how much aviation had progressed in such a small number of years before the second world war. It has often been reported that by 1939, 90% of the world’s passenger miles were flown in DC-3s. Where did this figure come from? I wouldn’t be surprised to find it was ginned up by Douglass’s publicity department.

No matter, even if the figure itself may be suspect, it has the ring of truth. No other airplane in the world could compare with it. In reading books on the DC-3 it was very often contrasted with another marvel of its time, the Boeing 247. That sleek speedster was in service a full year ahead of the DC-2. It was made in huge numbers for its time, 200 and they served in many places. It was a very advanced design and very speedy, cruising at 150 mph and carrying 10 passengers and a crew of two or three if a steward or stewardess was along.

Boeing at the time was a part of a manufacturing/airline conglomerate and all initial production was promised to member airlines. That is why outsider Jack Fry of TWA went to see Donald Douglas and contracted for what would become the DC-1,2 & 3. They would sweep all before them and the Boeing had but a brief year of leadership.

I started the old Williams 247 as outlined earlier in the thread. Considering what it is, its a pretty good kit. In the end, it looks like a 247 and that is what matters most to me. I painted it with a hardware store pewter that matched the color of the anodized AL that Boeing used pretty well. Sadly, it did not work out very well on this model. It went on patchy and the flakes are slightly visible.

I laid the Pointerdog decals over it and they went on well, no hoo-haw. The decal film was visible but not very much so. I intended to leave the decals on unprotected and pulled the masks off. My masking of the side windows was done with Micro Mask, big mistake! It did not want to come off without a fight and I ended up chisling and scraping some of them off. A few peeled off as I thought the should. Perhaps a thicker coat would have done better?

In any case, while handling the model to install details one of the decals came off. Drat! I put it back on with a dilute solution of warm water & School Glue. That got me thinking that maybe it was better to clear coat the decals after all. I quickly taped up the windows in a block and shot the 247 with Tamiya semi gloss out of a rattlecan. This only made the decal film more visible . . .

I’m not sure what to learn from this but I hope something will occur to me as the DC-2 & 3 are right around the corner and they will both be NM finishes. I hope I can figure this out as I have another 247 on the shelf and Mika at Arctic Decals in Finland offers a decal set for National Park Airlines, an outfit that combined with Western Air Express. That sheet has decals to make NC13337 while still with NPA markings . . .

Here are a few pics of the 247 now finished.
