Title: Airco DH.9. 1/72 Blue Rider conversion
Post by: Tim Mixon on September 15, 2022, 06:32:46 AM
My next project is kind of an ambitious one. Blue Rider has made a correction set to convert the Airfix DH.4 to an DH.9. The conversion set includes injection molded fuselage halves, white metal details and engine, and excellent decals for four aircraft. My plan is to make #D2854, 221 Sqdn RAF, Russia 1918

The Blue Rider fuselage halves have great accurate details on the exterior. The excessive wall thickness is a big issue though. Considerable grinding with a rotary tool was necessary to thin down the fuselage walls. I managed to do some damage to the exterior and fuselage seam along the way. Nothing that can’t be fixed.

  One half has been thinned with a rotary tool

  Airfix wings match the datafile reasonably well. I’ll reduce the rib effects considerably

  I’m replacing the supplied white metal Siddley Puma engine with an Ardpol resin one.

That’s all I have for now. Thanks for looking in!

Literally just put down the squadron/signal book on the DH9 which I picked up at the weekends show  :o (I also picked up teh KP version of this which is staying in its box until I've finished a couple of other projects though)

Will be following this with interest ;D
(Personally I like the look of B7620 markings though and noticed that this one was interned by the Royal Netherlands AF so had an interesting set of markings)

I'm very intrigued and excited by this build. A great start thinning the cockpit - as soon as you said "white metal" I figured they'd be a scale foot+ thick!

I agree Paul about 7620. I’m building 2854 as a trial run. I have another Blue Rider set (with Hellenic AF decals) that I’m saving for that aircraft.  I didn’t know that KP made a DH.9 I’ll have to look out for one.

I’m sorry, the fuselage is injection molded.  The engine and other details are white metal.

Tim, the KP kits are DH.9A's.
Ardpol had a resin kit of D2854 that looks excellent but they no longer exist and their kits are only available second hand.

I'll definitely be following this as I have the same Blue Rider conversion, but the Belgian version. (Only because I couldn't find the RAF one!)
Making notes!

I don’t know if Wingnut Wings leaving their website up is a blessing or a curse!  I didn’t intend on adding a lot of interior details to this model because of the rough and inaccurate interior surfaces. Once I started the fuselage framework, AMS kicked in and at 2am this is where I stopped:
(https://www.tapatalk.com/groups/hyperscale/download/file.php?id=152620)

This all the details I can add before painting the wooden effects.  Once that is done I’ll continue adding more details.

(https://www.tapatalk.com/groups/hyperscale/download/file.php?id=152621)

I primed the interior gray.  While that cures I started sanding down the rib effects on the wings. 

(https://www.tapatalk.com/groups/hyperscale/download/file.php?id=152623)

That’s all for now. Thanks for looking in!

Ah, gotcha! I did think white metal fuselage halves seemed like overkill!

Part IV

This is the instrument cluster.  Very busy little item.  I don’t have all the dials and gauges as per real one.  Looks a lot better without the magnification. 
(https://www.tapatalk.com/groups/hyperscale/download/file.php?id=153081)

Left fuselage half:

(https://www.tapatalk.com/groups/hyperscale/download/file.php?id=153082)


Both fuselage halves ready to join. I had to add a false bottom around the camera area to cover the gaping hole I ground into the fuselage. 

(https://www.tapatalk.com/groups/hyperscale/download/file.php?id=153083)

I’ve joined the fuselage together. Not too bad on the topside

(http:// https://www.tapatalk.com/groups/hyperscale/download/file.php?id=153084)

Bottom is horrible!

(https://www.tapatalk.com/groups/hyperscale/download/file.php?id=153085)

Super interior details. It is a pity that they will not be very visible though.

Another first class model in God's Own Scale in the making.

I do love what you're doing with this one Tim.  1/72 truly is the scale of the God's in my opinion; often because you need to be one to either do the work in this scale, or because God is the only one that can really see it when it's all closed up  ;D

Post by: Tim Mixon on September 23, 2022, 09:00:52 AM
I completed quite a bit this week.  Here I have attached the flying surfaces and added a lot of exterior details. Photo etch lacing, Aeroclub Scarf gun ring, elastic chord cockpit combing, and plastic access panels.

(https://www.tapatalk.com/groups/hyperscale/download/file.php?id=153329)

Bottom surface details are scratch built bomb racks, and access panels. The grate structure is an internal bomb rack I forgot to cut out. I’ll just paint the holes black.

(https://www.tapatalk.com/groups/hyperscale/download/file.php?id=153330)

Airfix has the struts molded together and have you glue them into these channels in the underside of the upper wing.
I decided to fill them in and only use the cabane struts for wing attachment.  This way I can paint the wings and not have unsightly gaps between the struts. 

(https://www.tapatalk.com/groups/hyperscale/download/file.php?id=153331)

Here is the model painted in PC-10.  Note the cabane struts in the upper wing. 


(https://www.tapatalk.com/groups/hyperscale/download/file.php?id=153333)

Next is to mask the PC-10 underside edging.

(https://www.tapatalk.com/groups/hyperscale/download/file.php?id=153334)

Now comes the rib and spar masking

(https://www.tapatalk.com/groups/hyperscale/download/file.php?id=153335)

Light overspray of CDL clear doped linen then remove the masks. Make sure you leave the edges masked!

(https://www.tapatalk.com/groups/hyperscale/download/file.php?id=153335)


Then lightly overspray the ribs to make them look translucent

(https://www.tapatalk.com/groups/hyperscale/download/file.php?id=153336)

Finally, remove the edge masks and touch up the PC-10

(https://www.tapatalk.com/groups/hyperscale/download/file.php?id=153337)

That’s all for now.  Thanks for looking in!

I expected more progress from you, Tim.  ;) Beautiful work! This is looking more and more like a larger-scale model with each update. And I appreciate the step-by-step for the underside shadow effect.

Post by: IanB on September 24, 2022, 04:33:44 AM
Nicely done.
Are you sure the wrap around included the ailerons and elevators? Normally the PC10 wrap is only around the outer edges of the flight surfaces.

Part VI

Painting continues:
I decided that the surfaces were kind of plain looking.  I really want more depth to the colors so I opted to mask the ribs again and lightly overspray Tamiya clear smoke. 

(https://www.tapatalk.com/groups/hyperscale/download/file.php?id=153414)

This is a little tedious masking it again but I have a good technique down and have gotten pretty proficient.

(https://www.tapatalk.com/groups/hyperscale/download/file.php?id=153415)

I’m really pleased with the results. I took my time and slowly sprayed the smoke color.  In the past I rushed and over did the effects. I think this is much better. 

(https://www.tapatalk.com/groups/hyperscale/download/file.php?id=153416)

Topside is much more  subtle than this photo shows

(https://www.tapatalk.com/groups/hyperscale/download/file.php?id=153418)

Future sprayed in prep for decal placement


(https://www.tapatalk.com/groups/hyperscale/download/file.php?id=153417)

I’m going to try and use some Pegasus decals for the cockades. I’ve had poor results with these in the past. I’m waiting for the second coat of micro film to set. 
Thanks for looking in!


Ian:  I think your correct.  I screwed up but it’s too late to change now 😞.  I’ll finish this one as is but not do it in on future builds.
Thanks.

Part VII

Decals are on and the tail plane and control lines are rigged. Pegasus cockades are slightly too large on the wings. They were problematic and needed repairs.  The Blue Rider decals took about ten minutes to release from the backing.  They are very thick as well. At least they held together!

Fantastic! And great paint scheme too. I once converted an Airfix DH 4 to a DH9. One of those plane types that looks more beautiful in 3d than in photos and plans. Great work!
