De Havilland Canada 1/72 DHC-4 Caribou prototype


Recommended Posts

Hi, guys.

After some preparing jobs, the "animal" is primed.

 

First underside,

than on top.

This process, of course, revealed some tinny gaps, some of them due to the little accident occurred and some to my mistakes.

None is visible in the pics, but they are there ad I will take care of the next week.

I'm anxious to unmask, but perhaps is too soon, even I'd avoid to leave the tape for too long. Will see.

 

Thanks for following.

Regards

Euge

Good afternoon.

Please excuse me, but I have a problem with "village photos" image hosting.

Many people can't see the images published after September the 1st or so.

Now I have tried to upload a pic on another domain (of a local modeling club).

I ask you for a feed back: here below you should see a red and yellow Auster.

Can you confirm please if it is so?

TIA

Sorry, no picture for me.....

 

Hope you can get it resolved, I’d like to check out your build!

I am not having a problems getting onto ACAM at the moment, there has been a fair bit of activity over there in the past few days. Maybe you need to clear cookies, etc? Could it be a region issue?

 

I can send a message to Ray to mention you have access problems.

Hi, Ray.

Cleared all what was clearable, tried yesterday at home and now at the job, with Avast Secure Browser, Chrome and even Internet Explorer with no result.

The region issue is the most likely reason, but it is fun to search the web for HTTP ERROR 418.

Thanks.

P.S. Now I'm stopping auto hijacking my thread and boring you with this problems until they will be solved.

Hi guys.

I have a new hosting site for the images.

I have updated the posts from September on.

I hope that they are visible now.

Next week end, if all works, I'll post new progress.

Thanks for your patience.

Here I am with an update regarding the landing gears.

I totally rebuilt the legs, because in the kit they were very simplified and not so much realistic.

 

Metal paper clips, styrene tubes, some putty.

A dry fit into the nacelles to check the high on both sides and that the model is aligned

Here the almost complete legs

And here more finished waiting for the paint to dry before some tubing.

Hope you like, if you can see the pics.

C-119 in RCAF Colours...

Interesting, but I don't understand how a Caribou can inspire a C-119, beside to be both transport aircraft. :hmmm:


A friend of mine asked me to prepare a sort of sample for the mechanical part of a testing instrument. Back to industry modeling after decades.
Therefore I have to clear the bench and temporally stop the Caribou project.
As last update of the year, I post a pair of pics of the painted gear legs in test fit.

Thanks for watching

The C-119 is sitting on my to do shelf...and the inspiration came from that era of aircraft, hence the inspiration of old school prop aircraft in RCAF colours.

Hi, everybody.
I've got some progress to report on the Caribou.
Also the kinematic of the main gear doors is really complicated.
In fact, the leg acts on some leverages that move the doors and make them close.
It took long to understand from the photos and the manual how it actually works, but at the end I did.
Doing something that looks like the real thing requires to work on the model sitting upside down on the jig. I had to do it now, absolutely before the painting stage.

There are not great details, but quite visible on the finished model.

 

So, you can see the doors with some added elements.

Here a first test fit on the aircraft.

Some more elements added and a first bit of paint.

All the doors painted inside.

Some views of the temporary assembly.

Hello everybody.
Thank you Underdog and Ray for your comments.
I've managed to get some work done in preparation for painting.
Well, the painting stage is not behind the corner, but I have to do some things now, otherwise such works could damage the painted model.

First the landing light.
The transparencies in the kit are quite nice and fit perfectly into the leading edge.
They are too much clear, so it is necessary to put something inside.
Closed the rear part of the lamp with a piece of polystyrene.

Made 2 little bulbs with stretched clear polystyrene. Still to be glued.

Like most of the prototypes, also the Caribou had a big nose probe with many sensors. Difficult to tell from the pics I have, how really they are shaped, but the main tube is there.

car297.jpg

 

In this web page there is an interesting photo of the DHC-4, revealing a sort of inspection panel on top of the nose.
Not quite a good fit, we should say, but an interesting detail.
In the next pics the process to make that rised panel.
A contour of vinyl tape to give the shape. Filled inside with white putty.

car298.jpg

 

Here the panel. Still needs to be sanded down a little.

car306.jpg

 

Onto the rear end now.
Unfortunately the fit of the tailplanes is not tight enough.
So I have enlarged the two mounting tabs and put inside the fin a little plate to get things straight.
Really not visible in the pic, but it is there, just above the tabs.

car307.jpg

 

I have spent some hours reading the maintenance manual, just for fun, but that way I discovered how tailplanes and rudder work.
Very interesting how, as always, DHC designs are an example of "robust engineering"
So I discovered, f.e. that what I thought were only 2 trim tabs each side, actually have different functions.
The inside one is called "spring tab" the outer "trim tab".
The spring tab, when the control column is in neutral position, is deflected upwards by 5 degrees, while the trim is at zero.
Long story short, these are the tailplanes with the tabs aligned as per the manual and the rudder.
It is a bottom view, since the actuating brakets are on the underside.

Thanks for watching.

Regards
