Cessna O-2A "Oscar Deuce", Vietnam war

58 posts in this topic

Hi there, Alex here!

I love to share with you my WIP of Cessna O-2A "Oscar Deuce" by Testors in 1/48.

Started on October 15th 2016, I supposed to get a simple project after a well elaborated Hughes OH-6A earlier, but it wasn't! It's still taking a lot of time indeed!

I collected a lot of pics and read some theads here and there before starting. During first check, the kit was quite attractive but basic. Some aftermarket items were a must. First of all about decals. The unusual "don't shoot" livery by Draw Decals was an exciting option at first, but after a long search on the web, I was quite sure it was a "fancy" livery, not on real life during Vietnam war. A second and good choice was given by Caracal decals by the sheet dedicated to O-2s.

Above a picture of starting point.....

 

Second step:

opening door & baggage door...

Next step: internal covering.

 

I checked a lot of pics again. Some aircraft had covering plain, other ones instead stitched on diamond pattern motif. I did the second choice by styrene and then painted with vinyl glue thinned in water to give a 'folds sensation'

Starting cabin floor.

 

Kit floor was undersized, definitely. It was time to get a new one by a sheet styrene, thickness 0,4mm...

 

IMG_2190.jpg

 

IMG_2312.jpg

 

Kit seats were much more similar to the civil version (C337) than the military ones. I got mine from an old Esci C172, giving a simplified upholstery (green Humbrol 155) and their chassis as well (green Testors 1734E)

Floor details:

- landing gear emergency hand pump,

- fire extinguisher,

- inspection manholes,

- avionics rack cable manholes (rear)

- first aid kit

Final touch:

- a map,

- lower seat belts (tan Humbrol 121),

- binoculars (later removed)

Instrument panel. Wrong size again, I've replaced it with a new one by styrene. Following original drawing, I got instruments in same position (or around so) to real aircraft, by Airscale etched/decals set...

Cloche (the only one parts taken in the kit for interior!) and panel in flat black...

 

IMG_2322.jpg

 

Pedals as well. Pictures said they are fixed on the back of the panel, not on the floor!

Avionics rack and rear juction box....

I've seen a lot of models here and there, on forums and magazine (e.g. FSM March 2016), unfortunately their configuration was not confirmed. By Google Images and some Vietnam veterans forums, I checked an almost right setting. So that shelves were secured to fuselage with just two vertical struts

New details....

some gaps were closed

 

IMG_2338.jpg

 

Many checkes between fuselage and wing were required... Then I got a perfect match

 

IMG_2335.jpg

 

Inside details according to photos collected

 

IMG_2364.jpg

 

M-16 was coming from a Tarmac crew set

 

IMG_2824.jpg

 

Then ceiling details. Documentation was a must again! A common mistake on O-2 was to fix upper seat belts on the back of the seat. They are fixed on the ceiling instead! (see two etched plates near the window)

Do you like this unusual twin pistons engine aircraft?

Hi all,

 

wires & cables were ready on late November...

 

A part of them were going down on a manhole close to the rack (see earlier)

Next episode will be about the engine! Yes, on December I decided to build Continental IO-360 starting with very few parts from my storage!

 

Stay tuned,

Alex :bye:

Folks,

In the next pictures I'll show you the engine section.

Twin piston engines aircraft could be a quite unfashionable subject, USAF livery in basic grey color does not give more attraction as well. So that I decided to give more details building the front Continental IO-360 engine starting by two old Esci Cessna C172 parts (to set up a SIX pistons propeller).

 

First of all I got the firewall bulkhead and internal structure according photos collected earlier...

 

IMG_2903.jpg

 

IMG_2905.jpg

 

IMG_2909.jpg

 

IMG_2910.jpg

 

.... then I started the engine itself

 

IMG_2914.jpg

 

IMG_2915.jpg

 

IMG_2916.jpg

 

Documentation is a must!

To be continued...

Cheers!
