Lockheed Hudson 50"


In the beginning, these antique plans drew m attention for years,...like 20yr!


But looking at them, some dimensions didn't seem right, although drawn very nice, and with LOTS of details...machine guns, LG etc.....I felt it needed more research....

Enter 3 views....LOTS of internet searching....fellows sending me info from as far away as Australia




Sigh.....I now have a satisfied group of bulkheads for the fuselage at corrected intervals..more or less....

I cut extra, and tested the crush strength of different widths, even lamination of light foamboard....weights etc.....

But plain hard balsa, cut with grain direction right, gave the best weight/strength combo.
So, because I wanted a fuse that was built with total internal open, I needed to make a fuselage jig......and wow in the different types!
But this is what I decided I could build and use..


I'm still working on powerplant combos......everything that will swing a 7"-8" prop with authority is way heavy...



So, here we are....at this point I'm thinking....
I have to finish a Buzzard Bombshell full size, and a " Fred"...and a 1/4 scale Skybaby for friends.


cheers

As Wikipedia says:
The Lockheed Hudson was an American-built light bomber and coastal reconnaissance aircraft built initially for the Royal Air Force shortly before the outbreak of the Second World War and primarily operated by the RAF thereafter. The Hudson was a military conversion of the Lockheed Model 14 Super Electra airliner, and was the first significant aircraft construction contract for the Lockheed Aircraft Corporation—the initial RAF order for 200 Hudsons far surpassed any previous order the company had received. The Hudson served throughout the war, mainly with Coastal Command but also in transport and training roles as well as delivering agents into occupied France. They were also used extensively with the Royal Canadian Air Force's anti-submarine squadrons and by the Royal Australian Air Force.
Hence the windows!

Folks...I HAVE to model this one plane:
"Outgunned and Outclassed" - adapted from an article by Michael John Claringbold

Pilot Officer Warren Cowan, 31 years old from Angaston SA, was killed in action on 22 July 1942, along with his crew, Navigator, Pilot Officer David Taylor, 33, from Hobart Tasmania and gunners Sergeants Russell Polack, 24 of Summer Hill NSW and Laurie Sheard, 20, of Nuriootpa, SA. They were the crew of a Lockheed Hudson Mk IIIA, tail number A16-201 on a solo armed reconnaissance mission. They died in a forlorn and lonely air combat against six Mitsubishi Zeros over New Guinea's northern beaches near Buna, the site of Japanese amphibious landings that were a prelude to the Kokoda campaign. What distinguishes this action from many like it in the early stages of Australia's war in the SW Pacific, is that an accurate account of what happened came from the other side.

They gave a distinguished account of themselves, so much so that 55 years after the incident, one of the Japanese pilots, none other than top Japanese 'Ace' of the war, Saburo Sakai, who was one of the pilots involved in the destruction of this aircraft, lobbied the Australian Government to present Cowan with a posthumous award for his actions that day.

Warren Cowan and his crew were on an armed reconnaissance mission launched from Port Moresby's Seven Mile Drome at 1130hrs, in response to the Japanese landings in the Buna Gona area. The aircraft they were flying had been assembled in Australia just three months before and delivered to No. 32 Squadron on 25 April 1942. They were looking for the destroyer escorts and the departing convoy heading back to Rabaul. Two hours after leaving Port Moresby, they reported they were 20 miles out to sea having flown over the north coast near Gona. Unreported by them but recorded by Japanese records it is fair to assume they did not locate the convoy and dropped their bomb load on Japanese positions at Buna on the return journey.

Unfortunately they flew into the Japanese air defence net cast over the landing area. A total of 18 Mitsubishi A6M2 Zeros belonging to a detachment of the Tainan Naval Air Group were rostered in three 'Chutai' (squadrons) of six aircraft, organised in two flights of three aircraft each, to patrol the landing area from their base at Lae further up the coast. The pilots were all combat experienced and had most recently been engaged in raids on Port Moresby. Saburo Sakai was the flight leader of the second flight, of the third Chutai, each aircraft marked with blue stripes around the rear fuselage. The other Chutai were marked yellow and red respectively. Sasai Jun'ichi was No 1 Flight Commander, Ota Toshio and Endo Masuaki were his wingmen. Flying with Sakai were Yonekawa Masayoshi and Mogi Yoshio.

Like Cowan, the Zeros failed to locate the convoy, but they did spot Cowan's Hudson, and his crew spotted them as was evident from his actions, which was basically to undertake a smooth descent to build up as much speed as it could towards Milne Bay.

The Zeros jettisoned their drop tanks and gave chase, sacrificing the increased range afforded by the lost fuel in exchange for speed to catch their quarry. Now it was just a matter of time, if Cowan adhered to the expected tactic of throttles to the firewall and attempting to gain maximum speed - which would not be enough to outpace the Zeros.

He didn't. In a move that startled his pursuers, perhaps realising that his expected course of action was forlorn, Cowan stood the Hudson on its wingtip in a very steep turn presumably assisted by the application of 'asymmetric power', and turned to face his attackers as perhaps his only remotely viable option. He fired his nose guns as he sped through the Japanese formation which broke up as he did so. The Japanese pilots were not carrying radios due to technical difficulties with their sets and the Zero airframe and engine. They were however, disciplined and experienced pilots and they regained their formation and tried to position themselves to attack despite defensive fire from the Hudson's dorsal turret. According to Sakai, it was ten minutes or so, an age in aerial dogfighting, before the Zeros could land hits on the Hudson thanks to Cowan's desperate maneuvering to evade them. Eventually the Zeros successively took out the Hudson's dorsal turret then set fire to the port engine, moments before it rolled into the jungle below and exploded, near the village of Popogo.

Cowan's actions impressed the Japanese pilots, but most ultimately became casualties themselves. Sasai Jun'ichi, the No 1 Flight Commander was lost just a month later in air combat with US Wildcat fighters over Guadalcanal. Sakai lost the sight in one eye but returned to flying late in the war as Japan's circumstances became dire.

In 1997, 55 years after the event, the only surviving participant in this action, Saburo Sakai, wrote to the Australian Minister for Veterans Affairs, Hon Danna Vale, requesting that Cowan's bravery be recognised. The Minister thanked him for his submission but advised that, regrettably, the request could not be legally honoured becasue the 'End of War' list had closed in 1945 thus closing off the avenue for a posthumous award.

This set of circumstances however makes for a unique anecdote in the history of the struggle in which Australia found itself in those dark days of 1942.

As a footnote, the wreck of the Hudson and the remains of the crew were discovered in 1943 by a USAAF search team who had been told of the wreck by villagers while they were recovering the remains of the crew of a C-47 Dakota crew that had crashed near Popondetta. The Hudson wreck was near the village of Popoga. It was realised it was not American and a later team including Australians recovered the remains of the crew in early 1945, which were subsequently interred in the Lae War cemetery although they are now in the Port Moresby Bomana War Cemetery (CWGC records).

Steel balls!.....so she will be with these markings/ motors(the Hudson s had a few different types)....pretty neat huh?

Those Emax motors have a pretty good power/weight ratio in my opinion - not sure how much better you can get at a reasonable cost.

Who is the designer - that looks like my sort of plan!!!

Here we go...




Back to work....
I've used a side view matching true lines...cut a spine and glued into place. I will cut a bottom spine and this should give me alignment of her fuselage. After it dries, I will begin adding 1/16" stringers.
I'm trying to build with a open internal fuselage, I would like to do the cockpit, rear bottom gunners position, and forward bombers position. :P making my scale pieces out of helium.....

2 fuse formers slightly short, no problem to cut and fix....it's the beginning....

My kind of builder. Pretty much exactly how I go about scratch builds. Often use a 3-view, or plan if the former/rib placements look reasonable, and then correct the profiles as much as possible and often use a different airfoil section/s. Currently have a small Bristol 170 fuse framed up, built using pretty much the same method. As you were saying, no matter HOW HARD I try to get all the fuse former height/width measurements correct, somehow I manage to get one wrong. This time all the measurements were correct, but I made one error transferring them to the paper templates. Fortunately caught it, before cutting the part. BTW nice jig setup.

Today's progress


I work 3 days a week, so progress is after I come home, do my 'chores'...then I can build.
I started by striping out some 1/16" and 1/8" ( really .06" and .09") then placing them. I have to work around all those sight seeing windows, and the bombardiers windows...using my trusty syringe with titebond glue, tack on both sides of the stick. Notice it's a joint with out cutting into the fuse former bulkheads...let's see how strong this way is


Thanks fellas on the comments about the jig...I got all my wood BEFORE the big price hike, had my Amish buddy cut and drill where needed. But I still have right at a hundred dollars in this jig....but those round fuselages....I'm no longer scared of them!!!

More progress




More wood....
I'm thinking of 'compartmentalizations' of flight deck then nose bomber's/ navigators, the top ball turret, and my belly gunners door. That way, if the details turn out to heavy, I can re-make them until the weights work out....
As you can see, my main spar will carry the motors and landing gear(I'm really hoping to be able to use my electric retracts)
I dream and plan that there will be a "U" shape of power/weight carrying/LG loads on this. Then everything else is just 'fluff'...
I have built many flintlock rifles, they basically are a barrel dressed in wood! Out along that 42" barrel is a 1/16" coat of maple. But once everything is locked into place, like a brick wall, a 'monolithic ' unit is formed.....
