1/32 Westland Whirlwind

[JeroenPeters]

Maybe better to 3D print the aileron. The kit's too thick and clunky and has misplaced panelling.

 

[GunnarO]

Note the sharp edges on the ailerons.

Hi Gunnar, that is very interesting! 

On the first drawing I thought the base of the aileron was flat, tapering out to the edge.

Like this:

 

 

But actually you're saying it should be this?

 

 

Or am I wrong?

 

[JeroenPeters]

In other words:

This is wrong?

[JeroenPeters]

I reckon most of the forward egde dissappears into the wing. Like this?

Only thing I don't understand is the cross section in the first drawing you shared...

 

[GunnarO]

You are correct that it’s wrong… the ailerons are diamond shaped. The spar you have placed in front on the ailerons are actually in the middle. 
 

Most of it is hidden inside the wing though.

Ok, thnx! I think this should fix that. Only need to add trim tab and surface detail.

My focus areas now are the ailerons, flaps and engines. The flaps need extra thickness, so i added a layer of greencard. Removed the indents of the gondola’s and sanding it all smooth now.

Put the whole edge in my edgemate to ensure an even thin edge.

 

[JeroenPeters]

Lots of sanding going on here. Added a layer of greencard and now sanding the shape into the flap.

 

[JeroenPeters]

The flap is by no means a straightforward construction. In this video you see the rails on the edges extending:

You are so lucky to have copies of the original drawings. ……

Thanks for the video Jeroen it shows so much a complicated flap arrangement for sure and you may of stated elsewhere but I imagine they will be deployed?

[GunnarO]

Great job Jeroen. This might come in handy. 

[Michaelscarborough]

I'm quite blown away by the level, or should I say depth, of corrections going on here...and the drawings and video you're working from. Really inspirational stuff.

Jeroen, who makes that instrument panel you showed??

Cheers from NYC,

Michael

Note that this instrument layout was only used by the first 18 Whirlwinds with serial numbers up to and including P6983. Later aircraft had the Blind Flying Panel Mk.1A with radius on top.

Yes Kevin! The kit does not offer the option to drop them, so i cut them and now am working on the details. Gunnar’s help is most welcome here (and everywhere else for that matter!)

Thnx! I haven’t studied the cockpit yet, but that sounds like a quick fix. I reckon more corrections need to be made in this area.

[JeroenPeters]

Hi Gunnar,

Do you know why the trim tab on the aileron is almost twice as wide on the technical drawing than on scale plans and photo's?

 

[JeroenPeters]

More goodies today. The Wingleader book is actually quite helpful in determining what is what on this plane. 
And decided to replace the thick canopy for a vacform that one. We’ll see how that goes.

 

[JeroenPeters]

Still lots of sanding and shaping on the flap. And adding detail to the rear nacelles that are attached to the flap.

in almost every photo you see some dropping of the flap due to hydraulics sinking. 
Visible in this photo is the flap indicator stick.

The drawings are showing early designs, some of them are pre production. During prototype testing many changes were made and we don’t have the latest versions of the drawings. Use photos and measure the length of the trim tab compared to the length of the aileron. The length of the aileron is known.

Ah yes. Cees already warned me about this. I corrected it and am now adding final details. Thnx!

[GunnarO]

The rear “panel line” on the flap is actually dividing the flap and the rear edge of the wing. That part of the wing is removed on the inside of the nacelle where the radiator flaps are located. 

if this makes any sense…

[JeroenPeters]

Does that mean that this panel line actually is not a panel line but a seperation?

in that case i should maybe fill this panel line? And add a strip to the bottom of the top wing?
