Amelia's Vega question...

Recommended Posts

Great question, and one with no good answer.

The Dora Wings kit doesn't provide the long range cabin tanks as basically nothing is known about them.

The old MPM/Special Hobby 1/72 Vega kits simply provided 55 gallon drums for the cabin tanks. This is pure fantasy!

The long range cabin fuel tanks installed in the various Vegas were borrowed/leased from Lockheed as they were very expensive to produce.

The cabin tanks in Earhart's Atlantic Vega had been used before in at least one other Vega.

I have seen a couple of photos of other record flight Vegas where the cabin tanks can slightly be seen through the cabin windows.

The tanks are aluminum and appear to be about 3/4 of the cabin height and at least 2 on each side of the cabin.

Their shape would be curved on their outboard sides, to match the symmetrical oval curve of the fuselage, and a straight vertical on their inboard side.

These cabin tanks were installed by removing the wing and then inserted from above.

The tanks, therefore, had to be sized to fit through this opening.

Good luck with your project.

I have a small, low-res photo of the long range fuel tanks installed in the cabin of Hubert Wilkins' first Vega, X3903.

Unfortunately, I am not setup to post photos here but if you email me I will send the photo along to you.

You may want to order the FAA Aircraft Records for Earthart's Vega, NC7952...

Request Aircraft Documents (faa.gov)

These records most likely will tell you how many cabin tanks were installed.

I recently was able to view the FAA Aircraft Records for Earhart's Atlantic flight Vega, NR7592.

These records shows 8 fuel tanks, total, installed for the Atlantic flight...

5 wing tanks and 3 cabin tanks.

The records show the cabin tanks installation personally signed off by Bernt Balchen, who repaired/reconditioned/modified the Vega for the Atlantic flight.

I hope this helps with your Vega build.

These are photos just prior to the world flight, not the Atlantic flight, but would the tanks have been similar? I know this is an Electra and not a Vega, but I'm curious if such extended range tanks had similar designs, albeit different capacities/sizes to fit specific aircraft.

There appears to be a similarity between the cabin tanks in the L10 Electra and the Vega.

Both tanks are aluminum and have those distinctive circular patterns on their ends.

However, the cabin tanks in the Vega were not one-piece, the full fuselage width, but two tanks, side-by-side to fill the width.

The cabin tanks in the Vega had to be smaller as they were installed through the cabin top, with the wing removed. This opening dictated their size.

This photo of the very first Vega, NX913 'Golden Eagle', lost in the 1927 Dole Race to Hawaii, shows the cabin tanks, two abreast...

I also have a photo of the cabin tanks in the Wilkins arctic Vega, X3903, and they appear identical to those installed in NX913.

The red and gold colors aren't readily noticeable when the wheel pants are installed.

 

Thanks Tim, Never knew they were like that ! But note that the Dora Wings Vega (like the 1/72 MPM one), is based on Wylam's drawings which incorrectly show too-small 30x5 wheels rather than the correct 32x6.  Knowing that, it really sticks out when I see photos of both models built.

I wonder if the Vega 5C drawings available from the NASM are better than Wylam's?

One set was done by Eberspacher, which I assume could be more accurate.

Eberspacher's drawing is of various versions of Winnie Mae and included (in a very small form), in the NASM Winnie Mae book. Think it also has some faults. Wylam's drawing is ok as a starting point as it gets the basics correct, but some of the secondary aspects are incorrect like the wheel/pants size and ailerons.

Oh dear. That airplane does not have any side windows, and the Dora kit has them. 

I guess it means they have to be removed from the model.

On Earhart's Atlantic flight Vega the plastic (a DuPont celluloid product called 'Pyralin') was removed from the cabin windows.

The window openings then had 2 wooden stringers added to their openings, which then were doped over with fabric.

You can see this effect on Earhart's Vega in the NASM...

I suppose simply painting over the clear windows on the Dora kit would suffice as the actual subtle draped effect may not be that noticeable.

I can remember building a model of the Winnie Mae way back in 1959 just before I left school. We were doing a project on explorers and pioneers. The model was left in a display cabinet at my old school. If my memory serves me right it was a Lindberg kit.

Hello

does anyone have any info on the additional tanks installed in the fuselage of Amelia's Vega for her trans-Atlantic flight?

nothing is planed  in the DoraWings kit...

I know it's been a rather long time since the question was first asked, but I finally found a line drawing of Earhart's Vega NR7952 (Atlantic flight) which indicates the location, and number, of the cabin fuel tanks.

This drawing comes from the NASM and shows 3 cabin tanks installed at the very front of the cabin.

There are 2 tall, thin vertical tanks, with 1 horizontal tank laid on top of the 2 vertical tanks.

These 3 tanks only take up a small portion of the very forward section of the cabin, right against the bulkhead at the back of the cockpit, extending to the front of the second cabin window.

Along with the 5 wing tanks this does make a total of 8 fuel tanks, as described in the FAA Aircraft Records for this particular Vega.

I have no idea of what references the artist used for their drawing so can't confirm its accuracy, but this is the first time I have seen a drawing of Vega NR7952 showing the cabin tanks.

Unfortunately, I cannot post photos here, but I can email a low-res scan if requested.
